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.

The lead of the motor is not only related to the rated voltage of the motor and the open circuit voltage of the rotor of the wound rotor motor, but also directly related to the current carried by the motor winding and the actual service condition of the motor. The selection of lead specifications should first be determined according to the withstand voltage value. The cable has a withstand voltage range. This rule must be followed when selecting. Below, the supplier of cable fault tester will take you to have an in-depth understanding of cables. Select the lead of corresponding voltage level according to the voltage requirements of the motor. The voltage level of the lead shall not be lower than the rated voltage of the motor winding. For example, for 10kV and 380V motors of high-voltage motors, the voltage value of the cable is very different. In addition, besides the voltage and current requirements, the insulation grade of the cable of the motor lead is also very important. According to the insulation grades of class B and h, the insulation heat resistance of the motor is different, and the material of the insulation material is also different. It must be noted that if the class B lead is used in the class H insulated motor, the possibility of lead damage and ground fault is very high. The cable fault tester supplier interprets the provisions of motor lead in the national standard: 1. Determine its necessity according to needs. According to the standard, if the motor has a power cord, or in order to facilitate connection with other equipment, provide a guide cord extending out of the motor base and a plug connecting the power supply line if necessary, the cord and plug shall comply with the provisions of the relevant standards of the product or the relevant standards of such equipment. Especially for small motors, winding wires can be used to connect with equipment or terminal blocks, but for motors that must undergo relevant insulation treatment, soft wiring must be adopted, and the provisions of terminal blocks must be added. Unless grounding is not required, these flexible wire bundles must have grounding conductors. Leads (including ends) require different colors and markings. Most motor manufacturers use three-color leads for three-phase motors, and some motor manufacturers use labels to distinguish them. However, for grounding wires, they are adopted according to standards. 2. Voltage and current requirements. The standard stipulates that the rated voltage of the guide flexible cable must be under the maximum working voltage of the motor, and its load flow must be at least equal to the load current of the service factor or 125% of the full load rated current, whichever is the larger. The flexible cord insulation shall withstand the working frequency withstand voltage test of the circuit. 3. Protection requirements for leads. In addition, there are measures to eliminate the possible tension, or guide the flexible cable (power cord) not to expose the motor. An insulating protective layer and clamping device are set at the outgoing part of the flexible cable to prevent the external tension from being transmitted to the internal wiring and prevent accidents caused by the rotation and displacement of the flexible cable. 4. Limitations and insulation requirements. In addition to other protective measures, the introduction of flexible cables into the motor shall be prevented. The clamping device for clamping and fixing flexible cables is made of insulating material, made of metal material and requires insulating lining.

Whether the cable is installed correctly or not is directly related to our personal safety, so it is very important to learn the correct cable installation method. First of all, we need to understand the precautions for cable installation: first, when the mining cable is placed in parallel with the heating pipeline, it shall be connected with a distance of 2m, and when interleaved, it shall be connected with a distance of 0.5m. Second, when the cable is placed in parallel or interleaved with other pipelines, it shall be connected with a distance of 0.5m. 3、 When the cable is directly buried, the direct burial depth of 1-35kV cable shall not be less than 0.7m. IV. when the cables of 10kV and below are placed in parallel, the clear distance between each other shall not be less than 0.1M, 10-35kV shall not be less than 0.25m, and the distance during interleaving shall not be less than 0.5m. V. the minimum bending radius of the cable shall not be less than 15d for multi-core cable and 20d for single core cable (D is the outer diameter of the cable). 6、 Discussion on 6kV and above cables. A. When placing the cable terminal, the semi-conductive barrier layer must be stripped off. The insulation shall not be damaged during operation. Knife marks and the environment with high and low resistance shall be prevented. If necessary, it shall be polished with sandpaper; The end of the barrier shall be flat, and the graphite layer (carbon particles) shall be broken and cleaned. B. The copper barrier and steel armor at the end of plastic insulated cable must be well grounded, and this criterion should also be observed for short routes to prevent electromotive force at the end of steel armor during three-phase unbalanced operation, even ignition and burning of sheath. Tinned braided copper wire shall be adopted for grounding outgoing line. Soldering iron shall be used for soldering when it is adjacent to cable copper strip, and blowtorch shall not be used for sealing welding to avoid burning insulation. C. The three-phase copper barrier shall be connected with the ground wire respectively. The detailed barrier ground wire and steel armor ground wire shall be led out separately and insulated from each other. The position of the welding ground wire shall be as low as possible. 7、 Fundamental requirements for cable terminal and center discussion: A. excellent conductor connection; b. The insulation is reliable. It is recommended to adopt radiation crosslinked heat shrinkable silicone rubber insulation material; c. Excellent sealing; d. Sufficient machine strength can comply with various operation conditions. 8、 The cable end must be waterproof and corroded by other corrosive materials to prevent breakdown caused by aging of insulation layer caused by water tree. 9、 Crane or forklift must be used for cable loading and unloading to prevent horizontal transportation and placement. Cable car must be used for large cable placement to avoid external force damage to the cable or scratch the insulation layer due to manual drag. 10、 If the cable cannot be laid in real time for some reason, it shall be stored in a dry place to prevent sunlight exposure, water inflow at the cable end, etc. Secondly, it is also a link that can not be underestimated, that is, it is necessary to conduct acceptance inspection on the installed cables to see if there are omissions. 1、 First, the user shall check and accept the cable to see if it is damaged, and the construction personnel shall test the resistance and insulation resistance of each cable with a multimeter to confirm whether the cable resistance and insulation are normal, and record it. 2、 The supervision personnel of the user are invited to accept the whole laying. The main acceptance items are: a) whether the insulation layer is laid smoothly; B) If reflective film is installed, check whether the laying of reflective film is smooth; C) Whether the barbed wire mesh is installed smoothly and fixed. D) After the heating cable is energized, check whether the surface temperature of the cable has increased significantly, and sign on the acceptance sheet for confirmation.

With the demands of modern life increasingly reliant upon technology it is vitally important to get the best equipment, as cheap as possible. Not only that but as consumers we should try and get as much value for our money by getting the most out of our equipment. Having the appropriate data cable is all part of this process and applies equally to large businesses and individual PC owners.There are various different types of data cable in use such as the Coaxial Cable, which is perhaps the most popular form of cabling as it is cheap and quite flexible. The Coaxial Cable is made of up a central copper wire surrounded by an insulator and a braided metal shield. The shield means it can be used over long distances at high speed, but the cable is usually only used for basic installations.Another type is a twisted-pair cable, which consists of two copper strands woven into a braid and covered with insulation. It is suitable for a local network with few nodes, a limited budget and simple connectivity. The drawback is that over long distances at high data rates it does not guarantee data integrity.Increasingly popular are fibre optic cables as they are lightweight, can accommodate a large bandwidth of up to several gigahertz and are immune to noise. These cables are very secure and allow connections over long distances. That said it is more expensive than Coaxial and twisted-pair cables and is therefore not ideal local network connections.Many of are using our PCs at home not just for working on spreadsheets and playing the occasional game of minesweeper, but also as part of our home entertainment system. When buying a new hard disk drive or HD DVD, Blu-ray, DVD or CD drive for your computer it is important to choose the most appropriate Serial ATA (SATA) data cable to connect the drive to the motherboard securely allowing for a direct path without bending the data cable too much. SATA is a single cable with a minimum of four wires creating a point-to-point connection between devices with transfer rates for SATA beginning at 150MBps.SATA data cables are much thinner than the old IDE cable drive and can be up to one metre in length. There are two speed levels too with SATA hitting up to 1.5 Gb/s and SATA II up to 3 Gb/s. In reality these types of speed are not reachable as it depends on the capacity of the computer.There are various different types of SATA available:• Straight Both Ends SATA Cable - This is the most commonly used as it has the same straight connectors at both ends and is the cheapest available. It is not ideal though if there is a large obstruction between the drive and the motherboard as it does not bend easily.• Straight Both Ends with Latches SATA Cable - This is the same as above but provides a more secure connection. The latch holds the data cable in place so it doesn't get easily pulled out.• Right Angled Drive Connector SATA Cable - This cable connector points downwards and is ideal for drives mounted higher up. However, it would be no good for drives near the bottom of a case or on the floor.• 270 Degree Drive Connector SATA Cable - Conversely this cable points upwards and therefore would suit drives near the bottom of a case and not those on top of a case or shelf.Data cables can be a real headache for businesses as their data centres try to keep up with modern technology and the growing traffic from the Internet, Smartphones and business applications. The numerous cables required to connect all the machines in data centres can cause huge costs to businesses as well as being an administrative nightmare. A typical computer server now requires at least eight or nine cables for tasks that should only need two connections and if you multiply that by the hundreds of servers in major data centres it can really get out of hand.Many companies are forced to buy extra equipment to manage all the necessary connections and coupled with the valuable office space this uses, it is costing a lot of money. In fact experts believe that as much as 15 percent of the cost of data equipment is spent on cabling. One of the solutions is to consolidate data cables if by moving to Ethernet, which has become the primary type of data cable linking almost all Internet-based networks, including the largest and most demanding telecommunications systems in the world.

As a new type of intelligent stethoscope, underground pipeline detector is used to survey underground pipelines. It is composed of transmitter, receiver and accessories. It is mainly used for underground pipeline positioning, buried depth measurement and long-distance tracking, as well as pipeline insulation fault point measurement and search. The equipment adopts multi coil electromagnetic technology, which greatly improves its depth determination accuracy and target pipeline identification ability. It can accurately track and locate the target pipeline even in the area with dense and complex pipelines. However, due to the complexity and diversity of underground pipelines, a better method is to combine various technical methods for general survey. The common site conditions in the operation of underground pipeline detector are as follows: 1. Track from the joint or handover box. Before the cable applies the transmitter signal, the common connector on the cable needs to be removed to track the target pipe. If all cables are to be tracked from the junction box, the transmitter can work in an inductive manner, placed on one side of the junction box and in line with the cable to be tracked. 2. Long distance tracking cable. In order for the transmitter signal to transmit a sufficient distance, it is necessary to remove the grounding connection of the cable. When the joint or joint is grounded for safety or lightning protection, surge arrester (anti overload) can be used to replace the grounding of the joint or joint, so as to protect the cable and make uninterrupted positioning possible. 3. Is the connector spike. Most cable connectors or connectors will generate spike pulse when the receiver responds. Working experience and understanding the local situation will help the operator to judge whether the spike pulse indicates that there is a connector box. 4. It's a metal guardrail. The cable is usually buried directly under the road outside the road metal guardrail, and the signal is combined with the continuous metal guardrail. The metal guardrail is close to the antenna at the lower part of the receiver, which is difficult to track. When it comes to the receiver, this difficulty can be overcome by making the internal antenna at the lower end flat with the metal guardrail. 5. Street lighting. Generally, the metal column of street lamp and the metal shielding layer of lighting cable are connected with the metal column. At this time, the transmitter signal can be connected to the metal column of street lamp. If the cement lamp post - unless the lighting cable can be connected to the maintenance rack and grounded, the transmitter signal needs to be connected to the metal shielding of the lighting cable. Knowing the relevant location and depth of lighting cables (and other street facilities on the same lighting system) can help track lighting cables. A connection point may apply signals to a large area of cables. It is also feasible to use street lamp posts to apply signals to other power cables, but the signal may be weak because the signal may have been transmitted for a long distance before returning to the substation and can flow out of the system again. At this time, the transmitter can increase the output power mode and increase the output power. This method can locate cables that are difficult to apply signals or inconvenient. For cables coming down from wooden poles, cement poles or lighting columns, the transmitter can be placed in sensing mode to apply a signal by making a right angle to the ground on the pole.
