Description:

T20 can generate a DC high voltage power up to 35KV, and makes discharge breakdown to the cable fault point, then the point is detected through cable fault location device (pre-locator) and the pin-pointer. This system adopts electric elements with high precision and stability, as well as special structure and crafts. Integrated voltage increase, rectification, pulse capacitance, and discharge control into one, this location system are easier wiring and operation, smaller dimension, lighter weight and easier carry.

Applications:

T20 Cable fault location system is mainly applied to locate the fault of high resistance and flashover on 6-35KV power cables.

Specifications:

1. LP30/2 fault location power

It is mainly applied to fault of high resistance and flashover on 6-35kv power cable. With integrated voltage set up, rectification, pulse capacitance, and electrostatic discharge control, the device discharges every 4 seconds each time,shortening the location time largely. Also the device has the advantages of easier wiring, convenient operation, smaller dimension, lighter weight, easier carry and so on.

Parameters:

2. WL20 Wave reflection method cable fault location set(TDR)

1. Multiple location methods:

Low voltage impulse method: Applicable for fault distance measurement for low resistance fault, short circuit fault, and open circuit fault. And apply to cable length, intermediate joints, T-joints, cable termination joints, and can be applied to correct the wave velocity.

Pulse current method: Applicable for distance measurement for high resistance fault, and flashover fault. Collecting signal from testing earth-wire through current coupler, it makes the user far away from high voltage, ensuring safety and reliability.

Second-impulse method: Applicable for distance measurement for high resistance fault, and flashover fault. Waveform is simple and easy for analysis and high locating precision.( This needs a second impulse coupler)

2. 200MHz real-time sampling:

Highest sampling frequency of the domestic similar devices. To keep the line with the world highest level.

With max location resolution of 0.4m, the device has smaller dead zone, so it is particularly efficient for near-end fault and short cable.

3. Touch operation & Mechanical button

Touch screen, gesture function bring about flexible operation.

Parameters:
