When Purchasing a Cable Fault Tester, Pay Attention to These Points to Avoid Entering the Pit
When Purchasing a Cable Fault Tester, Pay Attention to These Points to Avoid Entering the Pit
. the cable fault tester is an important tool for the power part to maintain the normal operation of the cable. It helps the power staff quickly reach the fault point and eliminate the fault in time, so as to ensure the normal operation and smoothness of the cable. Many people have introduced cable fault flashover and Gaozu fault, so pay attention to these points when buying to easily help you avoid stepping on the pit 1. You can't just look at the price, because what you need is an efficient and accurate testing equipment with perfect supporting after-sales service and pre-sales technical service guidance. These should be communicated and determined before purchase. It is worth paying attention to the details such as the list of accessories when the equipment leaves the factory, the use and installation after receiving, whether relevant technicians come to the site for guidance, or whether the use video is provided. The selection of cable fault detection equipment manufacturers is guaranteed. 2. Define your needs. This is to clarify the key parameters of the type and model of fault detection equipment you buy according to the scope of your use. The application scope of power cable fault test is relatively wide. It is compared with the communication cable fault tester, which is used to detect the fault point of communication cable. Many buyers, or purchasing departments, especially some power departments, are separated from the user department and the purchasing department. It is found that many remain unchanged in use, or even have no after-sales service at all. In fact, the basic principles of cable fault tester are almost the same, but the real competition is the service and product quality itself. I hope you can choose a cost-effective power fault detection equipment from the details when purchasing.
Three Common Methods for OTDR Optical Fiber Testing
Three Common Methods for OTDR Optical Fiber Testing
Optical fiber communication is a communication mode with optical wave as carrier and optical fiber as transmission medium. Optical fiber communication has become the main means of information transmission and the cornerstone of "information highway" because of its long transmission distance, large information capacity and high communication quality. Optical fiber testing technology is the most extensive and basic special technology in the field of optical fiber applications. OTDR is the main instrument in the field of optical fiber testing technology. It is widely used in the maintenance and construction of optical fiber lines. It can measure the length of optical fiber, transmission attenuation of optical fiber, joint attenuation and fault location. OTDR has the advantages of short test time, fast test speed and high test accuracy.1. Two basic formulas supporting OTDR TechnologyOTDR (optical time domain reflectometer) is a high-tech and high-precision photoelectric integrated instrument made by using Rayleigh scattering and Fresnel reflection when optical pulse is transmitted in optical fiber. The semiconductor light source (LED or LD) outputs light pulses modulated by the driving circuit, which are injected into the tested optical cable line through the directional optical coupler and movable connector to become incident light pulses.When the incident light pulse is transmitted in the line, Rayleigh scattered light and Fresnel reflected light will be generated along the way. Most of the Rayleigh scattered light will be refracted into the cladding and attenuated. The back Rayleigh scattered light opposite to the propagation direction of the light pulse will be transmitted to the light inlet port of the line along the optical fiber, and will be transmitted to the photodetector through directional coupling shunt and converted into electrical signals, After low-noise amplification and digital averaging, the processed electrical signal is scanned synchronously with the trigger signal emitted from the back of the light source and becomes a reflected light pulse on the oscilloscope.The returned useful information is measured by the OTDR detector, and they are regarded as time or curve segments at different positions in the measured optical fiber. According to the time from transmitting signal to returning signal, and then determine the speed of light in quartz material, the distance (fiber length) l (unit: m) can be calculated, as shown in formula (1).In formula (1), n is the average refractive index and â–³ t is the transmission delay. The attenuation a (unit: dB / km) can be calculated by using the power level corresponding to the incident light pulse and the reflected light pulse and the length of the measured optical fiber, as shown in formula (2):2. Five parameter settings to ensure OTDR accuracy2.1 test wavelength selectionSince OTDR serves optical fiber communication, the test wavelength shall be selected before optical fiber test, and only 1310 nm or 1550 nm shall be selected for single-mode optical fiber. Since the influence of 1550 nm wavelength on the bending loss of optical fiber is much more sensitive than 1310 nm wavelength, 1550 nm wavelength is generally used to test the whole process optical fiber backscattering signal curve of an optical cable or an optical fiber transmission link, whether it is optical cable line construction, optical cable line maintenance or experiment and teaching.The shapes of the test curves at 1310nm and 1550nm are the same, and the measured fiber connector loss values are basically the same. If no problem is found in the 1550 nm wavelength test, the 1310 nm wavelength test is certainly no problem.If the 1550 nm wavelength is selected for testing, it is easy to find out whether there is excessive bending in the whole process of the optical fiber. If a large loss step is found somewhere on the curve, retest with 1310 nm wavelength. If the loss step disappears at 1310 nm wavelength, it indicates that there is excessive bending at this place, which needs to be further found and eliminated. If the loss step is also large at 1310 nm wavelength, there may be other problems in the optical fiber, which need to be found and eliminated. In the test of single-mode optical fiber line, 1550 nm wavelength should be selected as far as possible, so the test effect will be better.2.2 optical fiber refractive index selectionThe refractive index of the single-mode optical fiber used now is basically in the range of 1.4600 1.4800, which should be accurately selected according to the actual value provided by the optical cable or optical fiber manufacturer. For G.652 single-mode fiber, if 1310 nm wavelength is used in actual test, the refractive index is generally 1.4680; If 1550 nm wavelength is used, the refractive index is generally 1.468 5. Incorrect selection of refractive index will affect the test length.In equation (1), if the refractive index error is 0.001, an error of about 35 m will be generated in the relay section of 50000 M. Small mistakes in optical cable maintenance and troubleshooting will bring obvious errors, which must be paid enough attention during testing.2.3 selection of test pulse widthIf the set light pulse width is too wide, strong Fresnel reflection will be generated, which will increase the blind area. Although the narrow test light pulse has a small blind area, the test light pulse is too narrow, the power must be too weak, the corresponding backscattering signal is also weak, the backscattering signal curve will fluctuate, and the test error is large. The set optical pulse width shall not only ensure that there is no strong blind spot effect, but also ensure that the backscattering signal curve has sufficient resolution and can see each point along the optical fiber.Generally, an appropriate test pulse width is selected according to the length of the measured optical fiber, and an optimal value is determined after one or two trials. When the distance of the measured optical fiber is short (less than 5000 m), the blind area can be less than 10 m; When the distance of the measured optical fiber is long (less than 50000 m), the blind area can be less than 200 m; When the distance of the measured optical fiber is very long (less than 2500 000 m), the blind area can be up to more than 2000 m.In the single disk test, the blind area can be less than 10 m by properly selecting the optical pulse width (50 nm). If the average value is obtained through two-way test or multiple tests, the impact of blind area will be less.2.4 selection of test rangeThe range of OTDR refers to the maximum distance that the abscissa of OTDR can reach. During the test, the measuring range shall be selected according to the length of the measured optical fiber, and it is better that the measuring range is 1.5 times the length of the measured optical fiber. If the range selection is too small, it can not be seen comprehensively on the display screen of the optical time domain reflectometer; When the range selection is too large, the abscissa compression on the display screen of the optical time domain reflectometer can not be seen clearly.According to the practical experience of engineers and technicians, the selection of test range can make the backscatter curve account for about 70% of the OTDR display screen, whether it is length test or loss test, better direct viewing effect and accurate test results can be obtained.In the test of optical fiber communication system, the link length is hundreds to thousands of kilometers, the relay section length is 40 60 km, and the single optical cable length is 2 4km. Good test results can be obtained by selecting the range of OTDR.2.5 selection of averaging timeBecause the backscattered light signal is extremely weak, the method of multiple statistical average is generally used to improve the signal-to-noise ratio. OTDR test curve samples the reflected signal after each output pulse, and averages the multiple samples to eliminate random events. The longer the averaging time is, the closer the noise level is to the minimum value, and the larger the dynamic range is. The dynamic range obtained with an average time of 3 min is 0.8 dB higher than that obtained with an average time of 1 min.Generally speaking, the longer the averaging time, the higher the test accuracy. In order to improve the test speed and shorten the overall test time, the test time can be selected within 0.5 3 min.In the connection test of optical fiber communication, satisfactory results can be obtained by selecting 1.5 min (90 s).3 three common methods of OTDR testingWhen OTDR tests optical cables and optical fibers, the test occasions include factory test of optical cables and optical fibers, construction test of optical cables and optical fibers, maintenance test and regular test of optical cables and optical fibers. The test connection of OTDR is shown in Figure 1.The test connection method is: OTDR - optical fiber connector - the first optical cable - the second optical cable - the nth optical cable, and the terminal is not connected to any equipment. According to the actual test work, there are three main methods:3.1 OTDR backward test methodThis method is mainly used to monitor the optical cable connection. The optical cable connection must be equipped with a special optical fiber fusion machine and optical time domain reflectometer (OTDR). After welding a fiber core, the welding machine will generally give the estimated attenuation value of this contact. This method of testing has three advantages:(1) OTDR is fixed, omitting the vehicles and a lot of manpower and material resources required for instrument transfer;(2) The test point is selected in the place where there is mains power without gasoline generator;(3) The test points are fixed to reduce the stripping of optical cables.At the same time, this method also has two disadvantages:(1) Due to distance and terrain constraints, it is sometimes impossible to ensure smooth communication;(2) With the continuous increase of connection distance, the test range and accuracy of OTDR are limited.At present, there are generally three methods to solve these problems:â‘ The use of mobile phones in the city and suburbs can keep the testers and successors in touch at any time, facilitate organization and coordination, and improve work efficiency.â‘¡ Contact by telephone. Make sure to connect one optical fiber (such as blue optical fiber unit and red optical fiber) to the optical telephone as the connecting line. Of course, the last optical fiber used for communication cannot be monitored because it cannot be contacted during fusion and fiber winding. Even so, the possibility of problems will be greatly reduced (if it is a 24 core optical cable, the probability of problems will be reduced to less than 1 / 24 of the original).â‘¢ When the optical cable connection reaches a relay distance, the OTDR moves forward.The test practice shows that these monitoring methods are effective to ensure quality and reduce rework.3.2 OTDR forward one-way test methodOTDR is tested at the first joint point in the optical fiber connection direction, and construction vehicles are used to transfer the test instruments and testers in advance. Using this method for monitoring, the test point and connection point always have only one disc of optical cable length, the attenuation accuracy of the test joint is high, and it is convenient for communication. At present, the length of one optical cable is about 2 3 km. In general terrain, communication can be ensured by using walkie talkie. If the optical cable has a corrugated steel strip protective layer, you can also use the magnet telephone to contact.The disadvantages of this test method are also obvious. Moving OTDR to each test point is labor-consuming and time-consuming, which is not conducive to the protection of instruments; The test points are also limited by the terrain, especially when the line is far away from the highway and the terrain is complex. Portable OTDR is selected for monitoring. The short-range test does not require high dynamic range of the instrument, and the small 0tdr has small volume, light weight and convenient movement, which can greatly reduce the workload of testers and improve the test speed and work efficiency.3.3 OTDR forward two-way test methodThe OTDR position is still the same as the "forward one-way" monitoring, but two optical fibers are respectively short circuited at the beginning of the connection direction to form a loop. This method can not only meet the optical fiber test of relay section, but also monitor the optical fiber connection. When testing the optical fiber in the relay section, the incident light pulse, reflected light pulse, joint point, fracture point, fault point and attenuation distribution curve can be clearly seen on the display screen of the optical time domain reflectometer. The OTDR test event type and display are shown in Figure 2, which can provide convenience for optical cable maintenance.When monitoring optical fiber connection, due to the increase of loopback point, the bidirectional value of connection loss can be measured on OTDR. The advantage of this method is that it can accurately evaluate the quality of the joint.Due to the test principle and optical fiber structure, there will be false gain and false large attenuation in one-way monitoring with OTDR. For an optical fiber connector, the mathematical average of attenuation values in two directions can accurately reflect its real attenuation value. For example, the attenuation of a connector measured from a to B is 0.16 dB, and that measured from B to a is -0.12 dB. In fact, the attenuation of this connector is [0.16 (- 0.12)] / 2 = 0.02 dB.4 ConclusionAs the main instrument of optical fiber communication,

Configuration and Management of Cable Fault Tester
Configuration and Management of Cable Fault Tester
With the development of the times, the use of electricity has also developed. Now electricity is everywhere around us. Electricity is transmitted to various places through cables, which provides great convenience for our life and work. Subsequently, the production of cables is becoming more and more perfect, and the types of instruments used to detect cables - cable fault tester are becoming more and more abundant. Today, let's talk about the configuration and management of cable fault tester. With the production scale, type and sales volume of cable manufacturers increasing year by year. As the cable fault is divided into high resistance value, low resistance value, broken line fault and composite fault, the cable fault tester sold on the market is generally configured in sets of high and low voltage, including many components and accessories. A set of equipment components are as few as 5-6 pieces and as many as 10-11 pieces. As a cable manufacturer, it is necessary to timely locate and deal with various cable faults in the factory production process to ensure the timely delivery of products; At the same time, it is also necessary to consider the location of sudden cable faults after the cable laying at the customer's site or during operation. Therefore, as a cable manufacturer, when purchasing the cable fault tester, it mostly adopts the complete set of high and low voltage procurement configuration. In case of direct buried cable fault location at the customer's site, the handling and transportation of the complete set of equipment must be transported by a special cable fault detection vehicle to ensure the quality of transportation. At present, the cable fault testers sold on the market are mainly divided into two categories. One is the cable fault tester designed based on the principle of echo method: mainly including intelligent waveform detection analyzer, conductor instrument and DC high-voltage generator, including console and DC dual-purpose high-voltage test transformer, electric container, ball gap, pointing instrument, etc. The other is a cable fault tester designed and manufactured according to the principle of electric bridge method: the components mainly include fault locator, capacitor, ball gap, pointing instrument, etc. The above two instruments for detecting cable faults are both coarse side positioning part and accurate positioning part of cable faults. When used at the production site and customer service site, the cable fault tester often needs frequent transportation or long-distance transportation. In order to ensure the normal transportation and use of cable fault tester, the daily maintenance and management of cable fault tester is particularly important. At the same time, the actual use frequency of cable fault tester is not high. Therefore, the probability of equipment failure during transportation is not very high. Optical cable fault detector is a kind of precision and valuable equipment. In order to ensure the integrity of the actual use of the equipment, as a cable manufacturer who purchases and uses the cable fault tester, the actual use of the cable fault tester must be subject to daily maintenance and management, so as to give full play to its role at the critical moment of cable fault in production and customer site, Ensure timely delivery of products and rapid resolution of cable faults at customer site. The following suggestions are put forward for the daily maintenance and management of the cable fault tester: the user of the cable fault tester must receive professional training to ensure the safe use of the equipment and prevent damage and electric shock during the use of the equipment. Establish the equipment account for the use of cable fault tester, designate a special person for the use and management of cable fault tester, and have a proper fixed place for storage and management. Before using the cable fault tester every time, the quantity, integrity, user and service time of each component of the cable fault tester shall be strictly checked and recorded. File the equipment with a debit note. After the cable fault tester is returned to the factory or workshop for use, a secondary point inspection must be carried out. The number of points shall include the number of equipment and the number of all accessories. The integrity of the equipment shall be checked before acceptance.

State of the Industry Report: Cable TV Tracker
State of the Industry Report: Cable TV Tracker
The introduction of cable tracker is one of the most significant developments in the television industry. The introduction of cable tracker every month to track and manage all cable channels was a step forward in the digitalization of TV. Now you can directly track your favorite shows, find out which shows are trending and which ones are on their way down, take action on new shows that will be available to watch later, see what is happening with your favorite channel and more.Cable providers have become the center of a new world, and there are many companies that are trying their best to be in the leadership. But it's not easy, because there is a lot of competition and they have to adapt quickly. In this article we will take a quick look at some of the most interesting products.Cable providers have long been in the business of delivering content to their customers. With the increasing speed of data availability and the rise in internet usage, they need to determine who is using their services and how much they are paying for it.With the rise of cable companies, most of us have been exposed to cable television. Since we are the ones that pay for these services, we should be able to get information about them as well.1. This section is dedicated to all cable providers, whether it is a local TV channel or a national cable company. What are the best ways to use your online customer database? What are the different methods of collecting information from your customers? Which data should you collect and how do you determine what kind of information to collect?2. This section is dedicated to all cable providers that want to improve their customer service by using data analytics and analytics software. How can they use this data in order to increase the overall efficiency for their customers? How can they improve their tracking abilities so that they will be able to better understand their customers' needs and wants? How can they identify trends in their customer's behavior and work towards improving it with actual data instead of guessing at what people want and need?Cable providers have a lot of cable channels that they have to pay for, and instead of spending too much money on them, they would like to find some alternatives.Unfortunately, they are not allowed to stream the content on their own servers anymore, since copyright infringement is punishable by law. Someone else has to be responsible for it, and that someone is the Cable Tracker.The Cable Tracker allows people who own a cable provider account or a satellite provider account (as long as they can see the satellite channel) to browse every single cable channel in their area and tell them what has been streamed on it. The user can easily create an alert if there is something that he thinks he should be aware about: when a movie is being played or if someone has accessed his account without his permission. After allWhat is Cable Tracker?Cable Tracker is a web based tool that allows cable providers to track viewer’s viewing habits across all of their channels. It provides them with a dashboard where they can view and analyze their subscriber’s viewing history.It seems like cable providers are focused on providing quality TV service to their customers. However, they are not the only ones to provide this service. Comcast, Aereo etc have faced similar issues of poor quality content that is being provided by their competitors even after paying for the content.There are 2 essential benefits of using these units:1. No need to spend money on continuous deployment and roll out of new technologies as there will always be a market for cable operators to offer their services. The same model can be replicated for any other industry or business sector because it doesn't require any investments in software development and deployment which can cost millions of dollars in order to implement new technology successfully. This also means that the overall investment required by an organization for new technology is minimal compared with other products or services thatThe idea is that a cable company will pay for the services of a cable picker who will go to different locations and collect the cables that are likely to go through a specific area.
Cable Fault Tester Has Become a Common Equipment for Cable Fault Detection
Cable Fault Tester Has Become a Common Equipment for Cable Fault Detection
As we all know, the rapid development of society is inseparable from the construction of infrastructure, in which the laying of power plays an important role, and the development of the whole society is inseparable from the stable operation of power. If the power failure is not solved quickly, it will have a negative impact on the regional economy, production and life. Therefore, the equipment that can quickly judge the cable fault point is extremely important. Cable fault tester is such a device. The working principle of cable fault tester is to first measure the reflected waveform of low-voltage pulse, and then use high-voltage pulse to impact the fault point passing through the cable to produce arc. When the arc voltage drops to a certain value, the medium voltage pulse is triggered to stably prolong the arc time, and then the low voltage pulse is sent out to obtain the reflected waveform of the fault point. After the two waveforms are superimposed, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stably prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse. Compared with the second pulse method, the third pulse method does not need to select the synchronous arc burning time, and the operation is simpler. The triple pulse method adopts the double impact method to prolong the arc time, stabilize the arc, and can easily locate high resistance fault and flicker fault. The triple pulse method has advanced technology, simple operation, clear waveform and rapid and accurate positioning. It has become the mainstream positioning method of high resistance fault and flicker fault. The third pulse method is an upgrade of the second pulse method. Full length and approximate position between cable fault point and test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, the working principle of power cable fault tester: the power cable fault tester is composed of three main components: power cable fault tester host, cable fault locator and cable path tester. The host of cable fault tester is used to measure the nature of cable fault. A Pathfinder is required to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault cable, the cable fault point is broken down, the cable fault is broken down, the electromagnetic wave occurs when discharging, and sound is emitted at the same time. Let the high resistance fault of the cable click through the arc. At the same time, the low-voltage pulse for measurement is added to the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and the arc surface is reflected. Due to arc combustion, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will have obvious changes in impedance characteristics, so that the waveform of lightning measurement becomes a low-voltage pulse short-circuit waveform, making the waveform particularly simple and clear. This is the so-called secondary pulse method to receive low-voltage pulse fault, which is equivalent to instantaneous short-circuit fault. The low-voltage pulse fault is combined with the traditional high-voltage pulse fault discharge method to discharge the low-voltage pulse fault to a positioning method (the secondary pulse fault is discharged into the high-voltage short-circuit fault in a positioning method, the low-voltage short-circuit fault is discharged, the high-voltage pulse fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, the low-circuit fault is discharged, and the low-circuit fault is discharged.
