The device also features a 12806 display and one-button operation. Inputting cable length automatically calculates the fault distance. The high-voltage source and bridge are integrated into a portable protective case. This device offers high voltage, is lightweight, easy to operate, and safe to use.
High-resistance breakdown points in cables after installation, especially linear high-resistance breakdown points that are difficult to burn down to low resistance, such as those at intermediate cable joints.
Flashover breakdown points, where the constant current source can maintain the arc after breakdown, a stable current flows through the bridge, and the bridge has sufficient sensitivity.
Low-resistance defects that have not yet broken down, such as insulation defects detected by a megohmmeter at low cable resistance but not breaking down under the operating voltage.
1. Galvanometer: Adjustable zero point for electrical balance;
2. Ammeter: Output current indicator (mA);
3. Voltmeter: High voltage output voltage indicator (kV);
4. High voltage indicator: This light illuminates when high voltage is output;
5. Display: Displays operation status;
6. Zero position indicator: When this light illuminates, it indicates that the voltage output is at zero;
7. Power socket: Instrument operating power supply, AC 220V connection port;
8. Fuse socket: Fuse installation location for the AC 220V power supply system;
9. Power switch: Position 1 turns on the AC 220V power supply, Position 0 turns off the system power;
