High Voltage Probe - HV Measurement

High voltage probe/divider is a part of voltage measuring device in high voltage (HV) systems where it senses the high voltage by direct contact and drop it to the low voltage and sends to the measuring meter AVM/DVM /CRO for AC/DC high voltage measurement and in case of impulse voltage (lightning, switching surges) will send to the oscilloscope (CRO).

Features

  • The high voltage probe or divider has the stray capacitance effect shielding.
  • The high voltage protection is provided at the low voltage side of the probe.
  • The HV probe terminal shielded cable of lead length 0.5m to 1m.
  • The common terminal (ground terminal) lead will be common to HV source ground & measuring meter common point (ground) terminal.
