I. Introduction

1 It is a one body trolley structure, easy handling at site.

2 You can do site test without complex wiring, because all test modes and switching voltage levels are automatically switched by weak control internal high-voltage switches.

3 It can quickly locate and point low resistance, high impedance fault leakage, flashover faults in power cable with a variety of 220V-220KV voltage level.

II. Characteristics

1 It integrates multi-gear DC high-voltage generator, multi-gear high-voltage capacitor, arc-stabling units and a variety of signal acquisition in one body, which facilitates fault location operation.

2 Switching between three gear test modes, two gear voltage levels is controlled by low-voltage weak electricity.

3 World's leading test method makes difficult fault detecting become very simple.

4 The requirement to operators’ level for technical equipment is low.

5 The DC voltage is up to 32kV.

6 Each stall of voltages, which is 16 / 32kV, can output up to 1536 J impact energy. It has longer ranging delay arc time and makes a loud voice on the fault point when locating.

7 It can do high impedance fault detection directly without burning.

6 Large wheels ensure a smooth, easy handling and site work.

III. Technical Indicators

1 Test methods: Arc reflection method, current sampling, and DC output.

2 Types of sampling signals: Arc reflection method, current sampling, and low-voltage pulse.

3 DC voltage output:

  0 ~ 32kV Negative   Maximum output current: 76mA

0 ~ 16kV Negative   Maximum output current: 152mA

4 Impact capacitor:

0 ~ 32kV 3μF Maximum output energy: 1536 joules

0 ~ 16kV 12μF Maximum output energy: 1536 joules

5 Ball-gap discharge: Weak electricity control. Discharge cycle can be adjusted within 3-12 seconds. It has a specially designed silencer, which meets the requirement of silence when fault happened to the initial end cable.

6 Protection:

   Zero voltage position protection: To prevent misuse, and to protect the safety of personal and the test product;

     Press "off" button, and it will release the remaining charge automatically through safety instrument inside to ensure safety.

7 It is equipped with extension cable tray, which can be composed of automotive cable fault location system.
