How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How does the cable identifier judge whether the cable is live? First: why should we judge that the cable is live: as an important instrument of power cable detection instrument, cable identification instrument has been used more and more widely. When there are multiple cables in the cable trench, it is necessary to identify a specific power-off cable, calibrate, move or cut off the cable, and other cables in the cable trench operate live, so the cable identification instrument shall be used for cable identification. Second: easy to use: compared with the cable fault tester, the use of the cable identification instrument is relatively simple. It is easier to use it by reading the instructions. Third: test example: since the cable shielding layer is usually connected to the ground, if other cables are also connected to the public ground in the cable bundle, the black output jack on the generator can be connected to the public ground, The return current is distributed in several cable shielding layers, and the return current is divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear. "Difference" means that the output current and its divided return current are in the same channel. As shown in Figure 4, there are 5 cables in Figure 4. Cable 4 needs to be identified. The "output current" of the cables to be identified is 20A. Assuming that the return current is evenly distributed among the shielding layers of all cables, there should be a return current of 4A in the cable to be measured. The difference in the cable to be identified is: 20A (output) - 4a (return) = 16A (difference). How to use the cable identification instrument I. working method of the cable identification instrument: the transmitter (host) is powered by 220V AC power supply, which is used for the power-off The cable to be identified, plus a fixed period, unipolar DC pulse signal. The output line of the transmitter is connected to the cable core and the grounding point or ground nail. The armor of the cable is disconnected from the earth, and the core is connected to the grounding point or ground nail at the far end. The loop can conduct pulse current, which can be read out by the meter on the receiver of the identifier. The current is determined by the loop resistance, and the loop resistance should be as small as possible. The wiring diagram of the identifier is shown in Figure 2. Note: during field use, if the grounding resistance is too small, the output current of the transmitter will also be large when the output adjustment knob is turned back to zero, and the protection circuit in the transmitter will act (shown as a small fast swing of the meter). At this time, the randomly configured 1 ohm 20W high-power resistor can be connected in series in the transmitter circuit. After the transmitter and receiver start working normally, the voltage induced in the sensor coil is displayed in the receiver header. The pointer swing direction of the header can display the current direction, that is, only the cable with current flowing out, the pointer deflects and swings greatly. This is the cable to be found. For all other cables, only the return current flows, the pointer deflects in the opposite direction and the swing is very small. The output adjustment knob on the receiver can adjust the signal strength. 2、 Wiring mode: 1. Before the test, cut off the tested cable, and the surrounding environment shall be in a safe state. 2. The generator is connected with the tested cable, and the red clip is connected with one or several cores of the identified cable. Connect the black clip to the ground nail. 3. Connect the core wire at the far end of the cable to the ground nail. 4. Disconnect the armor at both ends of the cable from the ground wire. 5. Plug the power cord into the power outlet. 3、 Identify the cable through the loop test. 1. In order to ensure the normal use of the instrument, pay attention to setting the test loop. 2. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. As shown in Figure 3, 3. The output current flows to the far end in the direction of the arrow in the cable, and all cores of the identified cable can be connected together through the earth return generator to obtain a clearer signal.
Buried Cable Fault Tester
Buried Cable Fault Tester
With the continuous strengthening of China's national strength, the development of power system is getting better and better. Cables have been widely used, and have high security because of their own characteristics. However, because most power cables are buried underground, it is inconvenient for people to determine the fault location. If the fault can not be eliminated in time, the resulting loss will be very serious. Underground cable fault tester introduces the underground cable fault tester, which is used to locate underground buried utilities. The basic form is divided into two parts, - one is the transmitter and the other is the receiver. The transmitter part is used to sense the signal to the pipeline or cable, and then the rod or receiver is used to locate the signal generated by the line. Can you find electricity, cable TV, telephone, water or gas pipes and tracer lines? Yes, any underground utility with metal structure and linear and preferably grounded along the path or end point can be located by any so-called cable fault locator. Did you find plastic (or any non-metallic tools)? No, the utility must have metal linearity for the signal of the locator to be transmitted downward. However, if a tracer line is buried next to or included in a non-metallic utility, the metal is metallic and can be located. Sometimes, a metal linear device (such as a plumber's snake or an electronic fish belt) can be inserted into the interior of a non-metallic pipe and positioned by applying a signal to the inserted device. What is the best choice of cable fault locator when there are many utility cables working underground and nearby? Multi frequency mode is preferred. By selecting frequency and power adjustments, this provides a way to isolate utilities from other facilities and reduce interference. Function introduction of underground cable fault tester the underground cable fault tester covers what is necessary to locate and track the path of wires, cables, pipes and conduits, whether buried underground or behind the wall. When you want to dig underground and avoid crossing buried utilities, this section contains a combination of locators and tracers to enable users to identify and mark routes and locations, saving thousands of dollars in maintenance costs. The function of cable fault tester (also known as cable fault tester) is the same as that of most buried utility locators. The transmitter is used to supply power to metal wires (cables or pipes) at a certain frequency by directly conductive connection to metal wires. Connect a single conductor of the transmitter to the pipe. The other - conductor is grounded perpendicular to the line and as far away from the line as possible. This forms a closed circuit that allows the current to flow. The current flowing through the pipe generates a magnetic field, which forms a columnar area around the pipe and represents a signal. A magnetic field is produced by an electric current rather than a voltage. The capacitance increases with the increase of conductor surface area. Therefore, the larger the conductor or pipe, the shorter the signal transmission distance. Buried cable fault detection is quite common in the actual power work, and the cable fault types and causes are also diverse. Therefore, there are enough advanced detection equipment to escort the power. Once a fault occurs, first analyze the fault types and causes, and then determine the fault location according to the fault state, Finally, the fault is handled to ensure the normal operation of the power supply system.
In Depth Understanding of Live Cable Identifier
In Depth Understanding of Live Cable Identifier
Everyone should be familiar with the live cable identifier. Xiaobian introduced it in the previous article. It is a very common cable construction and maintenance equipment. At present, there are both instruments for identifying non operating cables and instruments for identifying operating cables. Now we will introduce some knowledge about live cable recognizer. 1、 The transmitter panel of live cable identification instrument is introduced as follows: 1. Signal output port: this port sends the signal to the cable to be tested through direct connection coupling. The instrument can automatically detect the connection mode (direct connection or coupling). When no output line is connected to this port, the screen mode menu displays idle, and no signal is output at this time. 2. Frequency switching: the instrument has four output frequencies: low frequency, intermediate frequency, high frequency and radio frequency. It is suitable for different test systems and has strong anti-interference ability. When this button is pressed, the frequency will be switched between the above frequencies in turn. 3. Power regulation: the instrument adopts constant power output mode, and low, medium and high gears are optional. When this button is pressed, the power will be switched between the above gears. 4. Backlight switch: the instrument has a backlight controllable function. The backlight can be turned off during the day to save power. At night, the backlight can be turned on for test. When this button is pressed, the backlight will be turned on. When it is pressed again, the backlight will be turned off. 5. Power switch: the main switch of the whole instrument. When this button is pressed, the instrument enters the test interface. 6. Liquid crystal display of cable identification instrument: the instrument adopts liquid crystal display for man-machine dialogue. 2、 Precautions for the use of live cable identifier 1. If the operating cable has voltage and there is no load, there is no current flowing on the cable. At this time, the magnetic field cannot be detected. It is considered to be an uncharged cable, which is very easy to misjudge. 2. If the cable is not running, but if this cable is parallel to other running cables, there will be induced current and magnetic field. At this time, the instrument will also have indication, and misjudgment will occur. 3. If there are multiple cables in the cable trench, these multiple cables will generate a magnetic field. At this time, there will be a magnetic field generated by 50Hz current in the whole area. At this time, there will be a magnetic field in the whole area, which makes the discrimination impossible. It is easy to misjudge. 3、 Basic parameters of live cable recognizer insert the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamp the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. On the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At the identification point, identify each cable with receiving caliper B. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time.

Operating Instructions for Live Cable Identifier
Operating Instructions for Live Cable Identifier
1. Connect the transmitting source: the live cable identifier inserts the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamps the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. Both ends of the identified cable shall be reliably grounded. For cables that do not operate, the core wires at both ends can also be grounded. 2. Turn on the power switches of the transmitting source and receiver to check the direction: on the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At this time, the pointer of the receiver ammeter must deflect to the right, and there is an audible and visual prompt at the same time. If the arrow of the receiving caliper B points to the transmitting source end, there will be no audible and visual prompt, and the pointer of the current meter will deflect to the left. Remember the deflection direction of the receiving caliper gauge. 3. Identification: at the identification point, use the receiving caliper B to identify each cable. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time. On other cables, the pointer of the receiver current meter must deflect to the left without audible and visual alarm. The pointer of the current meter of the receiver deflects to the right, and the audible and visual alarm prompt is the cable to be searched and identified. This test result is unique. That is, no matter how many cables there are in the cable trench, when each cable is identified with the receiving caliper B, only the receiver current meter pointer on one cable (the cable to be found and identified) deflects to the right and gives an audible and visual alarm.
