High-voltage Cable Fault Tester

Product Introduction

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterBased onMURRAYThe design is based on the bridge principle, utilizing a switch-mode power supply to form a high-voltage constant current source, with an unloaded voltage.15000VShort-circuit Current5mAUsed for locating the breakdown points and defect points without breakdown in various cables after laying.

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterThe company has adopted full automation for 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 operational device, the one-touch operation completely replaces the traditional high-voltage bridge measurement method. It is easy to use, features a user-friendly interface, combines 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 function to record insulation conditions at different points.

In comparison to the wave reflection time-domain method,EDDQ-15Digital High-Voltage Bridge Cable Fault TesterEspecially suitable for:

1Post-laid cable with high dielectric breakdown points, particularly those difficult to achieve low resistance, such as the linear high dielectric breakdown of cable intermediate joints (mainly due to inadequate cable joint manufacturing processes. Under high voltage application, only leakage and tracking but no breakdown discharge occurs).

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

3The high-voltage bridge method only requires 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 cable
