Application Scenarios

The XHHV535-4TS+ is purpose-built for a wide spectrum of industrial and utility applications:

Core Feature Highlights

1. Three-Level Voltage/Capacitance Synchronous Switching

The system delivers consistent 2048J impulse energy across all three voltage ranges, maximizing discharge energy utilization for varying fault impedances:

2. Three Impulse Modes for Operational Flexibility

• Manual Impulse: Single-shot operation, ideal for precise fault location or repeated probing of difficult faults
• Periodic Pulse: Adjustable at 3s / 6s / 9s intervals to match different testing rhythms
• DC Withstand Voltage Output: Dual-purpose unit performs both impulse discharge and withstand voltage testing

3. Comprehensive Safety Protection System

• Zero-Position Start Protection: High voltage cannot be activated unless the voltage dial is at zero position
• Grounding Status Detection: Three-color indicator displays ground resistance status (green light: ≤100 Ω, ready to start)
• Automatic Discharge: Automatically bleeds residual charge from internal capacitors and the device under test when in stop state
• Overload Protection with Auto-Recovery: Activates when low-voltage side current exceeds 9 A for 5 seconds continuously
• Over-Temperature Protection: Alarm at 60°C, automatic shutdown at 105°C

4. Field-Optimized Convenience

• Dual-pointer meters (2.5-grade accuracy) for high-voltage side voltage and current, providing clear real-time impulse process monitoring
• Built-in high-precision sampling module for direct cable fault waveform output
• Integrated cart-mounted design combining DC high-voltage source, energy storage capacitors, discharge sphere, automatic discharge, and voltage switching into a single mobile unit
• Continuously adjustable high-voltage pulse output with uniform discharge characteristics
• Real-time high-voltage side metering eliminates safety risks associated with residual capacitor charge
