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 onMURRAYBased on the bridge principle, using a switch-mode power supply to form a high-voltage constant current source, no-load voltage15000VShort-circuit Current5mAThe technology is used for locating the breakdown points and non-breakdown defect points of various wires and cables after laying.

  GDZ-15The intelligent electrical bridge for cable fault location employs 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 a display and an operation device, it features one-touch operation, completely replacing the traditional high-voltage bridge measurement method. It is easy to use, user-friendly, with both text and graphics, and is safe and reliable.

  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 capability 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:

1The high dielectric breakdown point of the laid cable, particularly the linear high dielectric breakdown points that are difficult to achieve low resistance, such as the linear high dielectric breakdown of cable intermediate joints (this is mainly due to the poor manufacturing process of cable joints. Under high voltage application, only leakage and creeping arc discharge occur 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 cable ends.

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