Core Technical Specifications

Performance Characteristics

Dielectric Integrity

Ultra-low partial discharge levels ensure measurement accuracy during dielectric strength tests, complying with IEC 60270 standards.

Thermal Stability

Optimized heat dissipation maintains surface temperature rise below 100K under maximum load, preventing thermal runaway.

Impulse Handling

Designed for transient voltage scenarios with rapid energy absorption capability up to 5kJ per pulse.

Applications

• HV transformer impulse testing

• Gas-insulated switchgear (GIS) PD measurements

• Circuit breaker synthetic testing

• HVDC converter station commissioning

• Laboratory-based dielectric verification

Safety Compliance

Meets critical international standards:

• IEC 60060-1: High-voltage test techniques

• IEEE 4: Standard for HV testing

• EN 50191: Erection and operation of electrical test equipment

Installation Guidelines

1. Maintain minimum 2-meter clearance to grounded objects

2. Use corona rings above 300kV applications

3. Verify parallel resistor chains are balanced within ±0.5%

4. Annual recalibration recommended
