Trolley High Voltage Surge Generator 2048J 32kV Cable Fault Thumper with DC Withstand Test| XHHV535-4TS

 Trolley High Voltage Surge Generator with DC Withstand Test  XHHV535-4TS

The XHHV535-4TS is an integrated trolley-type high voltage test instrument combining a DC high-voltage source, energy storage capacitor bank, discharge ball gap, and automatic discharge safety system. Engineered for underground cable fault testing up to 35kV, it delivers precision impulse discharge with 2048J energy and built-in DC withstand voltage testing capability.

Key Features

• DC Withstand Voltage Test: Integrated DC high-voltage output mode for cable insulation withstand testing, eliminating the need for separate equipment
• Three-Stage Capacitor Bank: 4μF/32kV, 16μF/16kV, 64μF/8kV – automatically matched to voltage selection for optimal discharge characteristics
• Class 1.5 Precision: High-accuracy voltage divider provides real-time kV readings on the high-voltage side during both impulse and DC operations
• Dual-Mode Discharge: Timing auto-discharge (~7s interval) for continuous fault pinpointing, plus manual single-shot mode for precise distance measurement
• Auto Safety Discharge: Internal discharge circuit automatically drains capacitor residual voltage when stopped, displayed on panel voltmeter
• Overcurrent Protection: 8mA threshold with 3-second delay, preventing equipment damage from sustained faults
• Zero-Start Interlock: Voltage adjustment knob must return to zero before startup; prevents accidental high-voltage output
• Emergency Stop: Dedicated emergency stop button immediately cuts high-voltage output and activates internal discharge

Technical Specifications

Applications

Suitable for power utilities, cable testing contractors, and industrial electrical maintenance teams performing underground cable fault location, cable thumping, and DC withstand voltage testing on distribution networks rated 35kV and below. Compatible with TDR cable fault pre-locators and acoustic-magnetic pinpointers for complete cable fault location systems.
