HZ-523 Cable Sheath Fault Pinpoint Locator

HZ-523 Cable Sheath Fault Pinpoint Locator

The HZ-523 Cable Sheath Fault Pinpoint Locator delivers an output voltage of 10 kV or below, fully satisfying the requirements of GB 50150-2006. This includes handover testing and preventive testing of cable outer sheaths in cross-interconnection systems, as well as precise fault positioning of cable outer sheaths.

The device enables fast and accurate identification of grounding faults and leakage currents in 10 kV to 500 kV single-core and three-core high-voltage and ultra-high-voltage cable sheaths. Additionally, it supports 1-minute DC voltage testing at 5 kV to 10 kV for high-density polyethylene and PVC cable sheaths.

This instrument is an essential specialized tool for 10 kV–500 kV single-core and three-core high-voltage and ultra-high-voltage cable operation units, ultra-high-voltage cable engineering companies, power transmission and transformation engineering companies, and cable equipment maintenance teams.

Product Characteristics

Automatic Protection: Features automatic protection against overcurrent, overvoltage, and overheating.

Zero-Bit Start Protection: Provides safer and more reliable operation.

Unique Self-Discharge Design: As long as the high-voltage output is cut off, the internal high voltage automatically drops to zero.

Dual Pointer Meters: Equipped with current and voltage dual pointer meters for intuitive and clear display.

One-Button Mode Switching: Positioning mode and pressure-resistant mode can be switched with a single button, offering convenience and speed.

No Blind Area: The test range has no blind area.

Adjustable Receiver Sensitivity: Receiver sensitivity is adjustable for more convenient positioning.

Overcurrent Protection Switch: The overcurrent protection switch function makes both voltage resistance mode and positioning mode easy to use.
