Noyafa Cable Tester

Cable fault tester, we can analyze its role from the literal, which is specifically used to detect cable failure. So what can it be used in the end? In order to meet everyone's curware, Xiaobian should take everyone to understand the electric cable fault tester. We can analyze its role from the literal, which is specifically used to detect cable failure.

So what can it be used in the end? In order to meet your knowledge, Xiaobian should take you to understand the application scenario of cable fault detector. Interested friends are looking at it.

The cable fault tester is suitable for use in the power cable, high-frequency coaxial cable, local cable, street light cable, two parallel bubbles, road light cables, and short circuits, short circuits, and short-circuiting Fault, open circuit fault, and high-resistance leakage failure and high resistance flashing failure. The street light cable fault tester is dedicated to street light cable detection failure, in fact, in the cable fault tester manufacturer named cable fault tester model, similar to such a street light cable fault tester, communication cable fault tester such as In fact, the test principle is the same. Here is three types of detection methods for the street light cable fault tester.

First, use Zaudou Test: This method is the traditional street light cable fault detection method. The radius of the streetlights is typically between 0.4-0.6km, the street lamp spacing is 30-40m, and the entire line is like a trunk shape, and the load is more dispersed. To detect the phase of the cable, the right insulated resistance value must first turn the street lamp load, then select the intermediate point to disconnect, and perform the phase phase by the Aso table, check the insulation test, and to determine the direction of the fault point.

This status is basically not available. Second, use clamp current table detection: The principle of detecting street light cable is: The street light cable will be quickly generated, that is, no new damage to the street light wire cable), depending on the fault current of the power supply, the fault current of the power supply is very large, the change in the current of the current, when the detected current value is normal When the value is value, the front gear distance of the lamp bit of the normal value is the point where the fault point is located. Third, the use of street light cable dedicated fault tester: there is currently a lack of light wire and cable path detection, deep depth assay and fault point positioning three-in-one instrument.

This detector is small, placed in the handbox, light weight, single people can easily operate; power supply, no need for 220V power supply, suitable for field operation; cable path search, depth, fault point positioning synchronous completion, efficiency High, not affected by external interference; not affected by cable underground conditions (bifurcation, joint twisted, winding) Band, cement surface, etc. The detector is composed of a transmitter and a receiver, and the transmitter can use single-frequency transmit or radio frequency emission according to the site conditions (audio is suitable for a distance, and the radio frequency is suitable for near-distance, interference); the receiver passes inductive magnetic The rod induction signal determines the path and fault point of the street light cable, easy to operate, and accurately position the street light cable fault point. Three ways to detect street light cable failures, some are different from other general equipment, but the basic detection fault principle is connected, I hope everyone will consult with professional manufacturers when they communicate this type of equipment. Will you buy equipment that is suitable for you to cut high cost-effective.

About the application scenario of cable fault tester, we will introduce it here today, hoping to bring some help to people need.
