High-voltage Cable Fault Detection Instrument

Product Introduction

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterBased onMURRAYBridge-tapped principle, utilizing switch-mode power supply to form a high-voltage constant current source, no-load voltage15000VShort-circuit Current5mAUsed for locating the breakdown points of various wires and cables after laying, as well as the defect points without breakdown.

EDDQ-15Digital High-Voltage Bridge Cable Fault TesterOur company has implemented full automation testing, allowing for the automatic calculation and display of 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, offering ease of use, a user-friendly interface, and a combination of text and graphics for safety and reliability.

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

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

1Post-laid 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 arc tracking occur without breakdown discharge).

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 cable ends.

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 significant dielectric losses,PVCLow-voltage cables
