Buried cable fault tester With the continuous strengthening of China's national strength, the development of the power system is getting better and better, the cable has been widely used, and because of its own characteristics, it has high safety. However, because power cables are mostly buried underground, with the continuous strengthening of China's national strength, the development of power systems is getting better and better, cables have been widely used, and because of their own characteristics, they have Higher security. However, because the power cables are mostly buried underground, it is inconvenient for people to determine the fault location.
If the fault cannot be eliminated in time, the resulting loss will be very serious. Introducing the Underground Cable Fault Tester The Underground Cable Fault Tester is used to locate 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 onto the pipe or cable and then the rod or receiver is used to locate the signal produced by the line. Is it possible to find electrical, cable, telephone, water or gas pipes and tracer lines? Yes, any underground utility that has a metallic structure and is linear and preferably grounded along a path or endpoint can pass through anything called a cable fault locator to locate. Did you find plastic (or any non-metal tool)? No, the utility must have metallic linear properties so that the locator's signal travels down.
However, if there is a tracer line buried next to or contained in a non-metallic utility, the metal is metallic and therefore can be located. A metallic linear device (such as a plumber's snake or electronic fish tape) can sometimes be inserted into the interior of a non-metallic pipe and positioned by applying a signal to this inserted device. What is the best option for a cable fault locator when there are many utility cables operating under and near the location? Multifrequency mode is best.
This provides a way to isolate the utility from other facilities and reduce interference by selecting frequency and power adjustment. Underground Cable Fault Tester Features Introduction The Underground Cable Fault Tester covers what is necessary to locate and trace the path of wires, cables, pipes and conduits - cut, whether buried underground or behind walls. When you want to dig underground and avoid crossing buried utilities, this section contains a combination of locators and tracers that enable users to identify and mark routes and locations, saving thousands of dollars in repair costs.
Cable Fault Tester (aka Cable Fault Tester) Function Most buried utility locators function the same. Transmitters are used to power a wire (cable or pipe) at a certain frequency by direct conductive connection to the wire. A single wire from the transmitter is connected to the pipe.
Another - the wire is grounded perpendicular to the line and as far away from the line as possible. This creates a closed circuit, allowing current to flow. The current flowing through the pipe creates a magnetic field that forms a column around the pipe and represents the signal.
Magnetic fields are created by current, not voltage. Capacitance increases with conductor surface area, so the larger the conductor or pipe, the shorter the distance the signal will travel. Buried cable fault detection is relatively common in actual power work. There are various types of faults and causes of faults in cables. Therefore, there are enough advanced detection equipment to escort the power. Once a fault occurs, the fault must be first The type of fault and the cause of the fault are analyzed, and then the location of the fault is determined according to the fault state, and finally the fault is processed to ensure the normal operation of the power supply system.
