High-Voltage Bridge Cable Fault Tester

Introduction to Digital High Voltage Bridge Cable Fault Tester

  GDZ-15The intelligent electrical bridge for cable fault location is based onMURRAYBridge-type principle designed, with a switch-mode power supply to form a high-voltage constant current source, no-load voltage15000VShort-circuit Current5mAUsed for locating the breakdown points and non-breakdown defects of various wires and cables after laying.

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

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

Compared to the B-Reflect Time-Domain Method,KC-15The Digital High-Voltage Bridge Cable Fault Tester is particularly suitable for:

1The high breakdown voltage of the laid cables, particularly the linear high breakdown voltage that is difficult to achieve low resistance, such as the linear high breakdown voltage of the cable intermediate joints (mainly caused by insufficient cable joint manufacturing techniques. Under high voltage application, only leakage arcing occurs without breakdown discharge).

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 ends of cables.

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