High-voltage Cable Tester

Product Introduction

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterBased onMURRAYBridge-tapped principle, utilizing a switch-mode power supply to form a high-voltage constant current source, no-load voltage15000VCircuit short-circuit current5mAUsed for locating the breakdown points of various cables and the defect points without breakdown after laying.

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterImplementing full automation testing, the system 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 operational device, one-touch operation completely replaces the traditional high-voltage bridge measurement method, offering ease of use, user-friendly interface, and a combination of text and graphics for safety and reliability.

Integrating the digital bridge and digital megohmmeter, this device offers enhanced functionality, capable of automatically calculating the system's absorption ratio and polarization index. It allows manual setting of test time and features memory capabilities to record insulation conditions at different points.

Compared to the B-Reflect Time-Domain Method,EDDQ-15Digital High-Voltage Bridge Cable Fault TesterEspecially suitable for:

1High dielectric breakdown points of cables after installation, particularly challenging to achieve low resistance linear high dielectric breakdown points, such as the linear high dielectric breakdown of cable intermediate joints (this is mainly due to inadequate cable joint manufacturing processes. Under high voltage application, only leakage corona occurs without breakdown discharge).

2The high-voltage bridge balance method has no test blind spot, used for determining the breakdown points of short cables and near the cable ends.

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