Ultra-Low PD Performance

Vacuum-impregnated windings and triple-layer shielding ensure <5pC background noise - essential for accurate partial discharge measurements per IEC 60270.

Precision Resistance

5kΩ ±1% tolerance maintains waveform fidelity in:

• HV divider circuits

• RLC damping networks

• Oscillation suppression

Laboratory Applications

Partial Discharge Test Systems

Critical component in PD measurement circuits where resistor-generated noise must be below 5pC at test voltages.

DC Hipot Testing

Stabilizes output in 20kV DC test sets for cable and insulation testing.

Impulse Voltage Calibration

Provides precise wavefront control in 1.2/50μs lightning impulse generators.
