High-voltage Bridge Cable Fault Tester

Digital High-Voltage Bridge Cable Fault Tester Product Introduction

  GDZ-15The intelligent electrical bridge for cable fault location is based onMURRAYBased on the principle of a bridge circuit, using a switch-mode power supply to form a high-voltage constant current source, unloaded voltage15000VShort-circuit Current5mAUsed for locating the breakdown points of various wires and cables after laying, as well as the defect points without breakdown.

  GDZ-15The intelligent electrical bridge for cable fault location adopts fully automated testing. After the user inputs the full length of the cable, it can automatically calculate and display the fault distance. Utilizing a color touch LCD screen as both the display and operating device, it features one-touch operation, completely replacing the traditional high-voltage bridge measurement method. It is easy to use, user-friendly, and offers both text and graphics for safety and reliability.

  The digital bridge and digital megohmmeter are combined into one, offering enhanced functionality. It can automatically calculate the system's absorption ratio and polarization index, allows manual setting of test time, and features memory function to record insulation conditions at different points.

Compared to the B-Reflection Time-Domain Method,KC-15The digital high-voltage bridge cable fault tester is particularly suitable for:

1After laying, the cables exhibit high dielectric breakdown points, particularly challenging to achieve low-resistance linear high dielectric breakdown points, such as the linear high dielectric breakdown of cable intermediate joints (mainly caused by substandard cable joint manufacturing processes. Under high voltage application, only leakage and tracking arcs occur without breakdown discharges).

2The high-voltage bridge balancing method has no test blind spots and is used to determine the breakdown points of short cables and those near the cable ends.

3High-voltage bridge method only requires the uniformity of the resistance of the cable phase conductors for measurement. However, for cables with poor traveling wave transmission characteristics, such as those with significant dielectric losses,PVCLow-voltage cable
