VD Series High Voltage Probes 60kV -400kV DC

The VD series are floor standing, high voltage probes designed for rugged daily use. All capacitors are temperature, frequency, and voltage stabilized for the best possible performance. Resistors used have an extremely low voltage coefficient of resistance. Toroids as standard to minimise stray capacitance. Probes all have field defining toroids as a standard item to minimize the proximity effect (stray capacitance) and maximize the reproducibility measurement.

The high and low frequency calibrations are carefully matched before shipment. Very high frequency cable effects are also carefully compensated so accurate measurements can be made even when the cable length exceeds the pulse duration. No adjustments are necessary once the probes have been factory calibrated.
