Power Cable Fault Location Method
Power Cable Fault Location Method
Fault location method of power cable: Aiming at the problem that it is more difficult to determine the fault location of buried power cable than overhead line, this paper selects a representative example of fault location process of 10 kV cable in case of high resistance fault, and introduces the method of locating and locating the fault point by using secondary pulse method according to the fault nature. For the high resistance fault during cable operation, first consult the relevant data of the cable and master the detailed information of the cable; Use multimeter and insulation resistance meter to judge the cable fault type, and determine the corresponding test method according to the fault type; Use the fault tester to test the length of the cable, check whether the test results are consistent with the data, and preliminarily determine the distance of the fault point; Finally, the secondary pulse method is used to accurately locate the fault point, find out the fault point, peel off the cable and find out the cause of the cable fault, so as to take corresponding preventive measures. This method is easy to master, especially for short-distance faults, the test waveform is easier to analyze, and the fault distance can be determined quickly, which makes the cable test more efficient and the fixed-point positioning time shorter. Power cable faults are complex and diverse, which can be divided into open faults and closed faults according to fault surface phenomena; According to the grounding phenomenon, it is divided into grounding fault, phase to phase fault and mixed fault; According to the fault location, it is divided into joint fault and cable body fault; According to the nature of resistance, it is divided into broken line fault, mixed line fault and mixed fault. Among them, mixed line fault is divided into low resistance fault, high resistance fault and flashover fault. 1. Fault detection methods for different cable faults, the common detection methods include low voltage pulse method, pulse current method, secondary pulse method, bridge method, pulse voltage method, etc. [3]. This paper only introduces the three commonly used detection methods. 2. Low voltage pulse method low voltage pulse method is suitable for detecting low resistance fault (short circuit fault with fault resistance less than 200 & omega;) and open circuit fault. It can also be used to measure the length of cable and the propagation speed of electromagnetic wave in cable, and distinguish the middle head, T-joint and terminal head of cable. 3. Pulse current method pulse current method generally includes impulse flash method and direct flash method. The linear current coupler is used to collect the current traveling wave signal in the cable and generate the fault test waveform, so as to judge the fault condition and measure the distance between fault points through the waveform. The direct flash method is used to detect flashover breakdown faults, that is, the resistance at the fault point is very high, and flashover breakdown faults will occur when the voltage is raised to a certain value with high-voltage test equipment. The impulse flashover method is also suitable for testing most flashover faults. Because the waveform of the direct flashover method is relatively simple and it is easy to obtain more accurate results, the direct flashover method should be used as much as possible. 4. Secondary pulse method with the cooperation of high voltage signal generator and secondary pulse signal coupler, the secondary pulse method can be used to measure the fault distance of high resistance and flashover faults. The waveform measured by this method is simpler and easy to identify.
How to Find and Analyze the Fault Point of Buried Cable Fault Tester
How to Find and Analyze the Fault Point of Buried Cable Fault Tester
On site, the cable to be tested is high-voltage cable, and all three phases are short circuited. Usage when using the cable fault, first separate both ends of the cable from the system, and then connect the red and black clips of the instrument host to ab respectively. The measured short circuit distance between the two phases is 312m, and the total length of the cable is 639m. The same results are obtained when connecting to any other two phases. We determine that all three phases are short circuited. If the user knows the direct buried path of the cable, we can find it within 312 meters, and then use the transmitter red clip in the Pathfinder to connect phase A and the black clip to ground, and use the low-frequency high-grade loop resistance of 580 Ω. Because the cable is buried deeply before and after 312 meters, the depth measured by the 80% method is 3 meters, the gain 66db signal is about 675, and the signal is very stable without obvious attenuation. After the cable path is clear, boost and discharge phase a with high voltage, increase the voltage to 8Kv, fully discharge, start at a fixed point from 180m, and finally find the fault point. After communicating with the customer, excavate the fault point with an excavator for more than an hour. Host function of buried cable fault tester 1.

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.

Can People Fool Benevolent Brother's 'Alibi Trackers' and Escape?The Museum of Brother Benevolent has been broken into, and his Kindergarten Lunch Box has been vandalized. Both the Box and its glass case was destroyed by a small bomb. This happened at night.It is not clear how the vandal(s) got into the building, but it is huge and has many possible entrance points. There were no Alibi transmissions nearby at the time. Investigators are puzzled.What actually happened was that the sacred Lunch Box had been sent on a tour a few months earlier. Somebody took the opportunity to place the bomb in the Box then, and it was counting down until the fateful night.This was inspired by the novelCan bug trackers be used for tracking tasks other than programming?Bug trackers can definitely be used to track tasks other than programming bugs. As an example, our organization has successfully configured JIRA to handle our customer service department. JIRA is hugely configurable, and the manager at the time spent several weeks creating components, and custom fields to handle everything from new client signups, client setups, billing issues, client complaints and work requests, all the way to cancellations. We've been doing this now for several years, and the sales, client services, and the account management and accounts receivable departments are extremely comfortable with the process.A task is created for the client, and subtasks are created for each of the above issues that come up, whether it be the actual setup, work request, etc.Of course, whether or not something like this will work for you depends on your exact needs. With the examples you gave, I know JIRA would work for you. However, in your case, if you are just needing something like this for you and you only, there are many free or cheap lightweight online task management systems out there that would most likely work better.

Combined with the fact that bittorrent clients constantly inform the tracker about how much data they have downloaded and uploaded, this allows the tracker to record a users stats between sessions and even dynamic IP changes
Design of Consumptive Optical Fiber High Temperature Measuring Instrument
Design of Consumptive Optical Fiber High Temperature Measuring Instrument
1 IntroductionHigh temperature measurement plays an important role in aerospace, materials, energy, chemical industry, metallurgy and other fields. At present, in high temperature measurement, according to whether the measuring probe is in contact with the measured object, the temperature measuring instruments are divided into contact and non-contact.With the emergence of optical fiber technology, it provides conditions for the realization of contact temperature measurement. The contact optical fiber temperature measurement adopts a long quartz optical fiber as the temperature measurement probe and transmission system to keep the instrument away from the site with bad environment. At the same time, the optical fiber optical path is not affected by the environmental atmosphere, which greatly improves the environmental adaptability of the temperature measurement system. However, because the probe adopts the general radiation receiving principle, it is still difficult to solve the problem of emissivity. In order to overcome this problem, the principle of ash body temperature measurement is proposed. The colorimetric method can greatly reduce the influence of emissivity on the temperature measurement results. Under the best conditions, the influence can be reduced to zero. The advantage of such temperature measurement is that the temperature measurement response speed is fast, and the response speed is about 10s [3].The consumable optical fiber high temperature measuring instrument developed in this paper overcomes the above shortcomings and is a new method to measure the temperature of molten metal. Its temperature measurement accuracy is the same as that of the consumption thermocouple, but the temperature measurement cost is greatly reduced, which has great economic benefits and can completely replace the consumption thermocouple.2 principle of colorimetric temperature measurementColorimetric temperature measurement is a method to determine the temperature of an object by measuring the ratio of the radiance of the object at two different wavelengths. Its characteristic is that it can eliminate the interference caused by atmospheric, smoke, dust, ambient temperature and other factors on the measurement path.3 selection of working wavelengthAs can be seen from equation (3), it is very important to correctly select the wavelength and wavelength. Generally, the spectral radiance of the measured object is related to wavelength and temperature, as shown in Figure 1. The ordinate in the figure represents the radiation brightness of the blackbody, the abscissa represents the wavelength, and the temperature of the curve is getting higher and higher from bottom to top.From the curve in the figure, we can see several characteristics of blackbody radiation: (1) the total radiance increases rapidly with the increase of temperature. The higher the temperature, the greater the spectral radiance; (2) When the temperature is constant, the spectral radiance changes according to a certain law with different wavelengths, and the curve has a maximum value. The wavelength here is defined as that when the wavelength is less than, the radiance increases with the increase of the wavelength, and when the wavelength is less than, the change law is opposite; (3) When the temperature increases, the peak wavelength of spectral radiance moves to the short wave direction, the radiance of the object increases, and the luminous color also changes.The wavelength range is preliminarily set at 800 1000 nm, and there is no main absorption band of water vapor in this range, which can reduce the measurement error. When it is 800nm and 1000nm respectively, the relative sensitivity curve is shown in Fig. 2. The relative sensitivity of curve 1 in the figure is high. Therefore, it can be seen that it should be near 800nm. According to the relationship between the spectral response of the photodetector and temperature, it is required to have a good linear relationship. According to the linear relationship, it is better to take it near 950nm.After the experiment, the final choice = 890nm, = 940nm, the colorimetric temperature measurement effect is better.Fig. 2 relation curve between relative sensitivity and temperature
Principle of Cable Fault Tester
Principle of Cable Fault Tester
At present, the cable fault tester based on impulse flashover method used by the majority of users of power cable fault tester can easily roughly measure the distance of fault point with rangefinder when solving low resistance fault and dead ground fault of low-voltage cable (the distance test of such fault point does not need high-voltage discharge equipment, but uses low-voltage pulse method), However, the method of lighting fire, discharging and listening to sound is still used to locate the fault point. At the same time, the Pathfinder and fixed-point instrument of this kind of instrument are separated, which makes it impossible to synchronize the fixed-point when finding the path, and the fixed-point often deviates from the path. Moreover, due to the limitations of the principle, it is difficult to find the accurate path of the cable when finding the cable path, It is generally between 1-2 meters wide. Starting from practicability, hn-a10 series cable fault locator just makes up for the above defects. It can test the fault point location, buried depth and path synchronization of cable. The indication of fault, path and buried depth of the instrument is very intuitive, without technical analysis and completely independent of the operator's experience. It makes the originally tedious fault test work become a relaxed and interesting thing. Therefore, if the majority of impulse lightning cable tester users have another ht-tc cable fault locator and the original distance finder, they can form a set of perfect low-voltage cable fault tester. At the same time, the low resistance and open circuit faults of high-voltage cables can also be quickly fixed, and the work efficiency can be improved several times. In fact, the majority of power consuming enterprises and units rarely contact the maintenance of high-voltage cables in daily production, because the maintenance right of high-voltage cables is generally specially maintained by the prefecture and municipal power departments. The number of low-voltage cables is far greater than that of high-voltage cables. For enterprises, factories and mining units, residential areas, scientific research institutes, more developed towns and villages, colleges and universities, some small and medium-sized cities and county-level power supply bureaus, the solution of low-voltage cable faults is what they are most concerned about. In fact, what low-voltage cable users need is a tool tester with simple operation, convenient carrying, strong practicability, low price and suitable for field operation. Because the insulation strength of low-voltage cable is low, if the method of ignition and discharge is used to test the fault of low-voltage cable, we find that this method sometimes causes secondary fault. More seriously, after ignition and discharge, the service life of the cable will be reduced and the fault incidence will be increased, which will seriously affect the normal power supply and production.
Application Field of Cable Fault Locator
Application Field of Cable Fault Locator
The application field of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.

Basic Principle of High Voltage Cable Fault Locator
Basic Principle of High Voltage Cable Fault Locator
High voltage cable fault locator is a comprehensive cable fault detection instrument, which can test the high resistance flashover fault, high and low resistance grounding, short circuit, cable disconnection, poor contact and other faults of the cable. The cable fault locator is equipped with an acoustic pointing instrument, which can be used to accurately determine the accurate position of the fault point. It is especially suitable for testing power cables and communication cables of various models and different levels of voltage. The high voltage cable fault locator consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the 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, a pathfinder shall be used 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 power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time.
