The introduction of cable testerA cable tester is a person who tests all kinds of cables to make sure that they are safe and can be used with any kind of equipment.When computers first started being used for tasks, people thought they were very difficult to use. One of the main reasons for this is because the computers didn't have common vocabulary, which meant that users had to learn new terminology and concept at a very fast pace. Today, however, technology has changed so much that it's no longer necessary for users to learn new terminology - instead we can just speak with a computer and it will do all the work for us. The same applies to humans as well: we don't have to talk with someone else anymore!Tips for cable testerTo get a job in the cable industry, you need to pass certain tests. The way you write about this topic is equally important as the actual test itself.How to use cable tester?A cable tester makes sure that only the cables are connected to the right ports on a computer. On the other hand, an AI writer can make sure that a given section has all necessary information.For example, an AI writer can analyze how many people are using a certain online platform and which sections are most popular among them. The AI writer can then take this information and create content for this area in order to keep it relevant and updated.The specifications of cable testerThe cable tester is one of the most important tools in our work. Even though we are not directly responsible for it, we still want to follow some of the specifications that are defined for it. We also need to know how to test cables properly so that we don't damage our equipment and we get a high quality result.The product instructions of cable testerThe "product instructions" are the most important part of the product manual. The instructions tell customers how to use and maintain the product.The application of cable testerThe application of cable tester is a good example of AI that gets the job done. It can be used to identify weak points and gives you the opportunity to improve things.
Three Preventive Measures for Cable Leakage in Cable Fault Detection
Three Preventive Measures for Cable Leakage in Cable Fault Detection
It is very troublesome to solve the problem of the cable leakage, and the general cable fault tester is not equipped with the corresponding treatment equipment. In the specific operation, if a part of the cable joint end leaks, it can be applied again only by cutting off how many meters of the front-end development. If the reading of a cable has leaked, the foundation can not be used at this stage, so it can only be charged. Therefore, avoiding cable leakage is the appropriate choice, so as to take preventive measures. First, the cable joint shall be sealed. The sawn cable edges, whether stacked or laid, shall be sealed with plastic, and the special sealing sleeve for cable shall be selected to avoid the penetration of moisture and moisture. The fabrication of cable joints shall be carried out immediately after cable laying. Second, when purchasing cables, be sure to select manufacturers with solid quality. Because the residue and air outlet hole in the insulating layer are the starting point of water tree generation, the quality of cable is particularly important to avoid water tree embrittlement. Third, improve the management method of cable head production and processing technology. Once the cable leaks, the cable joint is usually the first to penetrate. Therefore, if the cable head is made well, it can increase the overall service life of the cable. For example, when the cable is separated from the semiconductor material layer, draw several vertically on the semiconductor material layer, and then peel off the semiconductor material like Gan Shu peeling. However, when cutting with a knife, if it is too deep, it will hurt the cable sheath and create opportunities for water supply and drainage trees. In addition, when the solder wire is used, because the switching power supply cannot be found, the gas furnace will be used to melt the solder wire immediately. At this time, the flame will destroy the copper shielding layer and cable sheath. Therefore, to avoid this kind of situation, UPS can be equipped. Since the time required for the solder wire is generally only 10min, the output power is 500W. PVC plastic PE corrugated pipe is selected, which has corrosion resistance, clean and bright inner cavity The compressive strength and ductility are excellent. Therefore, when the cable is buried and laid, the damage of the cable outer sheath can be greatly reduced. Design scheme of cable trench (pipe) and cable well. Due to the limitation of the standard, the cable laying adopts the method of buried or cable trench, and most of them are buried. If it belongs to the rainy area in the coastal area, there is water stored in the cable trench or cable well for a long time. Because the depth of the cable trench or cable well will exceed the depth of the sewer pipe, the drainage pipe is very difficult. Therefore, in the overall planning, harmony should be carried out, which is conducive to the drainage pipe of the cable trench (well). If it is impossible to ensure that there is no water in the cable well, the middle connector in the cable well shall be lifted with a support frame.

Analysis on Fault Location Mode of Power Cable
Analysis on Fault Location Mode of Power Cable
Cable faults also occur in the process of cable laying. Due to different cable laying methods, the difficulty of cable fault location increases gradually. Among them, the positioning of bridge, tunnel and groove is relatively simple, and the direct buried positioning is relatively difficult. Generally, a special cable fault location device (also known as cable fault tester) is used, which can be located in dozens of minutes, Special faults often take 4-5 days or even longer to locate. Now let's analyze the fault location mode of power cable. When using echo method to locate power cable fault, sometimes by transferring fault phase and wiring mode, complex fault will often be transformed into simple fault to quickly determine fault location. It is of great significance for the power supply user department to win time for the emergency repair of on-site lines. Low voltage power cables are generally multi-core cables. When faults occur in continuous use after laying, they generally show two core and multi-core phase to phase or phase to ground short circuit faults. Sometimes when it is detected that the fault waveform collected by one core is not ideal, it can be considered to convert the wiring to other fault cores for fault waveform detection, which often has unexpected effects, The collected and detected waveforms will become more typical and regular, so the specific location of cable fault point can be determined quickly. During the long-term on-site measurement of cable customers, it is found that the fault of small section copper core directly buried power cable (35mm2 and below) and aluminum core cable may be accompanied by short circuit and wire breakage at the same time. During on-site detection, converting short-circuit fault into broken line fault measurement according to the different fault nature of each fault core will often double everything with half the effort. For the medium voltage direct buried power cable with extruded armor as the inner lining, the fault is mostly caused by external mechanical damage. When the insulation core fails, the inner lining may have been damaged. When the cable insulation fault is special and it is difficult to collect the waveform with a professional cable fault tester, the acoustic method can be considered, When the high voltage pulse is directly applied between the steel strip and copper shielding layer of the cable, it will often be fixed quickly. In the field measurement process, we also found that when using the acoustic method to locate the fault point of low-voltage cable. When the high-voltage line and ground wire are connected between the bad phase and the metal shield or armor, due to the low resistance metal connection state of the insulation resistance of the two, the sound is very small, so the probe can not be used to listen to the fixed point, and the effect is not ideal. Through the actual listening side on the site for many times, it is found that the distance between the discharge ball gaps is appropriately increased. At the same time, if the high voltage and grounding wire are connected between the two faulty phases, the discharge sound will become louder and the fault point will be determined quickly.
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.
