High Voltage Test and Measurement

High voltage measurements have a variety of different requirements, and our devices are designed for most of these requirements. We can also offer custom designs for any applications, find a product in the tables below or contact us.

HV Probes: VD Series

  • Max DC/Pulsed V (kV) up to: 400/550
  • Max Frequency (Mhz.): 20
  • Can be used with either scopes or meters

Current Transformer: Pulse

  • Complete isolation from the circuit to be measured
  • Shielded construction, High accuracy (±0.5%)
  • Internal 50 ohm termination for coaxial cable matching
  • Variety of hole sizes to fit most conductors / voltages

HV Meter

  • Measures 500 to 40,000 Volts DC
  • Large LED display
  • Advanced solid-state design

Non-Contacting Voltmeter: Model 344

Capacitive Voltage Divider

  • Max Pulse Voltage in Oil up to 800kV
  • Voltage Division Ratio: 1:10.000
  • Output Connector – Type BNC Receptacle

HV Test Fixture TF-Series

  • Make accurate HV in-line measurements
  • View and measure AC ripple & noise on DC HV
  • Measure absolute HV DC to 0.25% @ 25 PPM stability
  • View and measure Trise, Tfall, overshoot & settling time
