Technical Specifications

Key Performance Advantages

Ultra-Low Partial Discharge

With PD levels <3pC at 70kV, this resistor minimizes electromagnetic interference—critical for sensitive measurement systems.

Thermal Stability

Engineered to limit temperature rise to 80K maximum during continuous 60-minute operation at full load, preventing thermal runaway.

Robust Transient Handling

Optimized for damping fast-rising impulses in lightning/switch surge tests (up to 1.2/50μs waves).

Industry Applications

Impulse Testing Systems

Suppresses ringing in Marx generators for accurate waveform compliance with IEC 60060-1.

Partial Discharge Detection

Enables noise-free PD measurements in cables and transformers per IEC 60270 standards.

Utility Substations

Protects diagnostic equipment during on-site HV testing of circuit breakers and GIS.

Safety & Compliance

This resistor meets critical safety benchmarks:

• Designed for arc-flash risk reduction in CAT IV environments

• Compatible with IEC 61010-1 insulation standards

• Non-inductive winding prevents voltage overshoot
