HIOKI VT1005 AC/DC High Voltage Divider

The HIOKI VT1005 is an AC/DC high voltage divider. It divides voltages of up to 5000 V (5000 VRMS, ±7100 Vpeak DC to 4 MHz) and outputs them eg. to a power analyzer such as the PW8001, PW6001 and PW3390. The voltage dividing ratio is 1000:1.

  • Compact and robust AC/DC high voltage divider.
  • Max. input 5000 V (±7100 Vpeak, no measurement category, anticipated transient overvoltage of 0 V), 2000 V CAT II, 1500 V CAT III.
  • Measurement accuracy ±0.08% (DC), ±0.04% (50/60 Hz), ±0.17% (50 kHz).
  • Frequency flatness ±0.1% amplitude band 200 kHz typ., ±0.1° phase band 500 kHz typ. (after phase correction by the power analyzer).
  • Measurement Band DC to 4 MHz (-3 dB).
  • Noise Resistance: CMRR 80 dB typ. (100 kHz), differential input method.

Applications of the HIOKI VT1005 AC/DC High Voltage Divide

In order to measure the efficiency of inverters with a high degree of precision, power from DC to high frequencies has to measured with high accuracy. The HIOKI VT1005 has an excellent frequency flatness for the accurate measurement at frequencies ranging from the fundamental wave to switching-frequency components. Applications are:

  • Evaluation of the efficiency of Wireless Power Transfer (WPT) systems.
  • Evaluation of the efficiency of inverters that use SiC power devices in industrial equipment.
  • Evaluation of loss in transformers and reactors designed for use in high-voltage circuits.
  • Evaluation of the efficiency of inverters that use SiC power devices in electrical railways.
  • Evaluation of the efficiency of solar inverters that support high-voltage input.
