Technical Specifications

Key Performance Advantages

Ultra-Low Partial Discharge

Consistently maintains <3pC PD at 75kV - essential for noise-free measurements in sensitive HV test environments.

Flexible Operation Modes

60-minute operation at full load + unlimited continuous use at 80% rating - ideal for extended testing protocols.

Thermal Stability

Engineered to limit temperature rise to 80K maximum during peak operation, preventing performance drift.

Industry Applications

Impulse Voltage Testing

Damps oscillations in 75kV impulse generators for accurate waveform compliance with IEC 60060-1 standards.

Partial Discharge Measurement

Enables precise PD detection in cables and transformers per IEC 60270 requirements.

Research & Development

Provides stable resistance in high-voltage prototype testing and dielectric studies.

Safety & Compliance

Designed for maximum safety in critical applications:

• Non-inductive winding prevents voltage overshoot

• Compatible with IEC 61010-1 insulation standards

• Corona-free design for reduced EM interference

• Thermal overload protection

Operational Guidelines
