VD Ultra-High-Voltage Probes (>100kV)

Brand: North Star
Origin: United States

VD ultra-high-voltage probes with different voltage ratings and response speeds.

Key specification options

Maximum DC/pulse voltage (kV): 70/115 / 100/160 / 150/230 and more
Maximum frequency (Mhz.): 25 / 20 / 16 and more
Rise time (ns): 14 / 16 / 20 and more
Cable length (ft.): 30
DC accuracy: <0.1% / <0.2%
Accuracy, 10 Hz.-1 Mhz.: 1% / 2% / 3% and more

Measurement and application

High voltage measurement requires the probe, cable and receiving instrument to be considered together. The waveform, test medium, measurement location and grounding arrangement all influence the setup.

Selection and connections

Specify whether the task concerns DC, AC or pulses, and describe the test environment and instrument input. Follow the selected model instructions for installation, grounding and operation. Suitability under one set of conditions does not establish suitability under another.
