How to Select the Appropriate Cable Fault Tester
How to Select the Appropriate Cable Fault Tester
Cables bear the great responsibility of transmitting electric energy, so it is very important to ensure the normal use of cables. What if the cable fails? This requires the use of cable fault tester to find out the fault point, and then repaired by professional staff. Different types of equipment have different configurations, so how to select the appropriate cable fault tester? Let's have a look. As the cable fault types are divided into high resistance, low resistance, broken wire and composite faults, the cable fault detectors sold in the market are generally high and low voltage complete sets, 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 production process in the plant to ensure timely delivery of products; At the same time, we should also take into account 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 detector, it is a complete set of high and low voltage purchase configuration, and the equipment components are 6-10 pieces. In case of direct buried cable fault location at the customer's site, the handling and transportation of the whole set of equipment must be transported by a special cable fault detection vehicle, otherwise the transportation quality of the instrument is not guaranteed. There are also some special cable fault detectors, such as the railway household coat cable fault detector. More specifically, it can be called the railway single core cable outer sheath fault tester. These two configured cable fault testers are suitable for railway. According to the characteristics of railway cable outer sheath fault, under the condition of separation of cable sheath and shielding layer, The bridge method or voltage drop method is used to initially measure the grounding fault of the cable outer sheath, and then cooperate with the special receiver to accurately find the fault point. The instrument has a built-in high-precision measurement unit. If there is a good auxiliary cable sheath, the fault is initially measured by the bridge method. Without moving the instrument to the opposite end, the test instrument can directly display the fault distance and realize rapid measurement. If there is no good auxiliary cable sheath, the fault distance of the outer sheath can also be calculated by testing both ends of the outer sheath of the faulty cable and using the resistance (voltage) comparison method, If the resistance value of the sheath per kilometer is known, the fault distance of the outer sheath can be calculated through the single end voltage drop test of the outer sheath of the faulty cable. The outer sheath transmitter and the fixed-point receiver can realize the accurate fixed-point of cable sheath grounding fault. At present, the cable fault detectors sold on the market are mainly divided into two types: one is the cable fault detector designed according to the principle of echo method: the components mainly include intelligent waveform detection analyzer, Pathfinder, DC high-voltage generator (including console and AC / DC dual-purpose high-voltage test transformer), capacitance, ball gap, pointing instrument, etc. The second is a cable fault detector designed and manufactured according to the principle of bridge method: the components mainly include fault location bridge (high and low voltage bridge), pointing instrument, path instrument, wave reflection fault location instrument, etc.
Fault Location of Power Cable and Fault Location of High Resistance Cable
Fault Location of Power Cable and Fault Location of High Resistance Cable
Power cable fault and high resistance cable fault are common problems of cable fault, and also belong to medium and high frequency problems of cable fault. Below, the author analyzes and writes the methods of cable fault location of these two cables, hoping to have a certain reference for everyone in case of cable fault. 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.
Brief Introduction of Cable Identification Instrument
Brief Introduction of Cable Identification Instrument
The working principle of the cable identification instrument needs to add a special signal to the identified cable, which should be received by a special receiver. Using this characteristic, the cable to be found can be identified. The cable identification instrument works according to the following principles: the cable identification instrument consists of a signal generator, a receiving clamp signal detector and an indicator. The signal generator mainly generates special pulse modulation signals, which are added to the stopped tested cable through the output line. The receiving clamp is used to find the tested cable on site. When the receiving clamp detector detects the special signal applied to the cable, The electric meter pointer on the signal detector swings synchronously with the frequency of the applied signal, while the signals detected on other cable lines are much smaller and in the opposite direction. It is easy to determine the tested cable by indicating the amplitude and direction of the electric meter. When the receiving clamp signal detector is used in combination with the signal generator, it can be used to distinguish the charged state of the cable, or assist in finding the short circuit position of the cable. When receiving clamp signal detector is used, clamp the cable with clamp.

The Benefits of Using the Right Non Contact Voltage Tester
The Benefits of Using the Right Non Contact Voltage Tester
You hear continuous chirping and see a series of flashes confirming that the tester has detected the voltage. This type of voltage tester allows you to test voltage without having to open or splice wires. This tool can also be used to dim the basement in situations where the light does not work, a small but helpful feature as it is the only model we have tested.In fact, the mere presence of an electric field can trigger this type of voltage tester. Non-contact voltage testers work by measuring a small amount of current coupled to the circuit between the tester and ground. Since they are light, they can detect this current without direct contact.A contactless tester is a device which allows the user to check the voltage of a variety of electrical appliances without touching wires or parts. The functioning of these devices is based on the use of capacitor couplings to detect electric fields. The built-in sensors at the top of the tester detect the presence of voltage without touching the conductor, socket or power cable.Volt sticks are designed for a specific purpose: to detect the presence of AC voltage. The electric fields connected to the AC voltage are present in the current conductor, and the reason for this is the requirement of direct contact with the conductor. Another reason is that electric fields have to build up and collapse in order to induce a current in the volt rod circuit, which happens with alternating voltages.If you refer to the capacitors in the video above, you can see that the current flows at an AC voltage. With a DC voltage, the electric field must build up and remain in one direction until a current is induced in the voltage stick circuit, and since there is no volt stick in the circuit it does not indicate the presence of a DC voltage. This is the reason why testers do not work with DC capacitors and why transformers do not work with DC voltage.A few ticker markers, including the Southwire Dual Range non-contact voltage tester can detect two voltage ranges. The higher voltage range is the default, while the lower voltage range (tension range) at the upper end is kept at 1,000 V. Most voltage testers do not register voltages below, giving Southwire a significant advantage over simpler models.Electrical testers are a good value option with impressive IP67 water resistance. Mid-range models such as the SouthWire non-contact voltage tester are designed to withstand the elements. If you need an outdoor quality tester, you will appreciate the IP67 waterproof housing of these pins.The Small Non-Contact Voltage Tester (NCVT) is ideal for NCVT electricians working with HVAC, ventilation and air conditioning systems (HVAC). Not only is it the most reliable model in the price range of non-contact voltage testers, but also has the new Voltbeat technology that enables self-testing. When something goes wrong the problem can be detected by the sensor or from a device such as a nearby voltmeter or oscilloscope.
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. In case of equipment failure and missing accessories, it shall be handled in time, and the corresponding economic losses shall be investigated to ensure that the equipment is in good condition before use, And signed by the user and the manager for confirmation.
