Product Description
Cable Outer Sheath Fault Locator Set
Detecting Cable Outer Sheath Fault Via MURRAY Bridge/Step Voltage and Clamping Current
The Cable Outer Sheath Fault Locator Set quickly and accurately identifies hidden dangers including grounding faults and excessive leakage current in the outer sheath of 10kV-500kV single-core and three-core high-voltage and extra-high-voltage cables. This system can also perform 5kV-10kV, 1-minute DC withstand voltage tests on high-density polyethylene and polyvinyl chloride cable sheaths.
Key Applications
- Essential for maintenance of 10kV-500kV single-core and three-core high-voltage cable systems
- Critical tool for extra-high-voltage cable engineering companies
- Valuable asset for power transmission and transformation engineering operations
XHHG521A Model Features
Designed based on the MURRAY bridge principle, the XHHG521A locates breakdown points in various wires and cables, including defects with low insulation resistance values. The system features:
- High-voltage constant current source with electric voltage regulator and R-type transformer
- Button-controlled voltage adjustment (7500V no-load voltage, 100mA short-circuit current)
- High-sensitivity amplifier and galvanometer for balance indication
- Integrated high-voltage source and bridge in portable protective box
- One-touch operation with automatic fault distance calculation
- Four-terminal resistance measurement eliminates lead resistance errors
