» Technical Details


Transformer A double wound step up transformer is used for boosting the voltage. The transformer is made of super enameled wire, CRGO core and polyster film/paper for insulation. Voltage Control A step less auto-transformer is used for controlling the output from zero to maximum. The auto-transformer has built in arrangement for zero start interlocking. Input Voltage 230 or 400 volts single phase 50 Hz AC supply. Output Voltage Upto 300 KV Capacity Upto 50mA on HV side. Rating Continous for testing and 15 minutes at full load Control (a) Knob to control the output voltage from zero to maximum or push button n case of motorized model.
(b) Knob to control the tripping current in steps. Meterring Moving coil / digital KV meter and milliamp meter will be provided to indicate output Voltage and leakage current. Terminating The negative and positive terminals are brought out on suitable insulators. Positive or negative polarity can be supplied at Earth Potential on request. Protection The unit consists of fast acting DC relay which actuates instantaneously if the testing current goes beyond the pre-set level.b) The HV will not actuate if variac is not at zero position (To protect the transformer against transients on HV side & to protect the operator) Rectifier Silicon diodes with RC network are used for rectification in bridge or doubler or multiplier or half wave circuit.
