Cable Sheath Fault Locator

XHHD523L high voltage cable sheath fault locator designed for detecting and pinpointing outer sheath ground faults on 10kV to 500kV single-core and three-core power cables. Delivers 0-10kV square wave output with adjustable frequency (0.2Hz-5Hz) for step voltage fault location and DC withstand testing per GB50150-2006 standards. Dual-mode one-key switching between fault locating and withstand voltage modes. Includes high-sensitivity receiver with A-frame for step voltage method and receiving clamp for cable tracing. Essential for HV cable commissioning, preventive maintenance, and post-installation defect investigation by utility companies and cable engineering contractors.

XHHG521A Murray Bridge cable sheath fault pre-locator with 7500V no-load output and ±(0.2%·L±1)m precision for pre-locating outer sheath breakdown points on power cables. Based on the Murray bridge balance principle using a high-sensitivity amplifier and galvanometer for balance indication with four-terminal resistance measurement to eliminate lead resistance errors. One-touch operation — enter cable length, press test, instrument automatically calculates fault distance. Unlike TDR wave reflection methods, the bridge balance method has zero blind area, making it ideal for fault location on short cables and near end terminations. Integrated high-voltage source and bridge circuitry in a 25kg portable protective case.

XHHD523L cable outer sheath fault locator designed specifically for cross-interconnection system verification and EHV cable commissioning on 10kV to 500kV power cable networks. Delivers 0-10kV square wave output with 0.2Hz-5Hz adjustable frequency for step voltage method fault pinpointing, plus DC withstand testing capability per GB50150-2006. One-key toggle between locating mode and withstand mode. Essential for transmission asset managers, EPC commissioning contractors, and HV cable system engineers responsible for sheath integrity verification on cross-bonded cable circuits with link boxes and SVL installations.

Based on the Murray bridge principle, this 7500V cable sheath fault tester locates high-resistance breakdowns and insulation defects with high precision. Automatic fault distance calculation and zero blind spots make it ideal for short cables and near-end diagnostics.

Cable Sheath Fault Locator XHHD523L 10kV Square Wave Output for Fast Accurate HV Cable Fault Detection-XHHD523L Product Overview The XHHD523L Cable Sheath Fault Locator is a professional-grade instrument designed for fast and accurate fault detection on high-voltage power cable outer sheaths. With a 10kV square wave output voltage and maximum 200mA output current, this device fully complies with the Chinese national standard GB50150-2006 for cable outer sheath withstand

Product Overview The XHHG521A Cable Sheath Fault Locator is a precision diagnostic instrument designed based on the MURRAY bridge principle, specifically engineered to locate breakdown points in various power cables and identify defect points with low insulation resistance values that have not yet fully broken down. The system integrates an electric voltage regulator with an R-type transformer to form a high-voltage constant current source, featuring push-button voltage

Engineered for 10kV-500kV HV cable testing, this cable sheath fault locator delivers precise fault detection with adjustable square wave output and automatic protection. With one-key mode switching and dual-pointer display, it meets GB50150-2006 standards.

Low Leakage Current Cable Sheath Fault Locator for 25kV/5min Withstand Voltage Test With the full deployment of urban network transformation, many power supply bureaus, construction teams, and design units are encountering 110kV XLPE cables for the first time. Due to time constraints and limited experience, many cables fail the withstand voltage test (10kV/1min). Most outer sheaths use HDPE material, which passes the factory DC 25kV/5min withstand voltage test with leakage
