Introduction
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 magnetising current over voltage frequency is applied.
It is an independent unit having coupled Motor and Generator with Control Panel to control the motor and the output voltage. Depending upon design requirements AC or DC motors are used.
Salient Features
Brief Technical Detail
The Control Panel consists of direct on-line starter 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 consist of variac, indicators, control switches, and operator safety features. In case of DC motor, DC drive is used to control/vary the frequency.
