Induced Over Voltage Test Set (I.O.V.W.) / D.V.D.F. Exporters to Saudi Arabia, United Arab Emirates (UAE)


Induced Over Voltage Test Set is used for testing the strength of insulation between turns and between other points of the transformers etc. as stipulated by BIS or other standard specification. For this test Double Voltage is applied across L.T. terminals for one minute, and to control the magnetizing current over voltage frequency is applied.

It is and independent unit having coupled motor and Generator with Control Panel to control the motor ad output voltage. Depending upon the design requirements AC or DC motors are used.

  • No foundation required
  • Unit ready for use.
  • Fine Voltage control.
  • Short Circuit Protection.
  • Calibrated Voltage and Ampere Meter.
  • Easy to operate complete with operator safety features.
  • Guaranteed for one year against manufacturing defects.
  • Efficient After Sales Service.


The control panel consists of direct on-line or Star-Delta depending upon capacity of the setup. Moving Coil Voltmeter and Ammeter are provided to indicate the output voltage and current. Frequency meter is provided to check output frequency. While for measuring input voltage and current, moving iron type meters are used. Other included parts consists of variac, indicators, control switches and operator safety features. In case of DC motor, DC drive is used to control/vary the frequency.
