AUTOMATIC VERSIONFollowing parameters can be set by 4x4 matrix keypadA) Output Test VoltageB) Leakage / Trip Current LimitC) Test Duration (Time)HV built in printer, with Rs232 interface & with both the feature are considered as Automatic version HV test set. In Automatic HV Test Set both types like with AC output & with DC output instruments are available.

SEMI AUTOMATIC VERSIONFollowing parameters can be set by push button with potentiometer / thumb wheel switch.A) Output Test VoltageB) Leakage / Trip Current LimitC) Test Duration (Time)

• Once above parameters set and the high voltage is started the instrument will automatically raise the voltage.
• On reaching of the test voltage, control circuit will start to command to timer. After completion of duration motor will come back.
• Object Test Fail Indication is given.

MOTOR GENERATOR UNITThis test setup is generally used to perform induced voltage test on the transformers. This set up consists of the USED motor and generator combination to develop the required voltage and frequency. Both generating unit and the drive motor are mounted on a common metallic frame.

GENERATING UNIT

• Input : 0 to 415 V three phase, 50 Hz through the dimmer unit.
• Output : 50 to 900 V three phase, 100 Hz.
• Capacity : Suitable to test the distribution transformers
• Transformers KVA ratings shall be specified by the customer.

The input and output are terminated on the suitable terminals on the unit.Make : KIRLOSKAR / CROMPTON / AEC / SIEMENS / NGEF (or eQUIVALENT)

DRIVING UNIT

• Input : 415 V three phase, 50 Hz through the dol /star delta starter.
• RPM : 1440 or any suitable speed (or eQUIVALENT)
• The input supply terminals are terminated on the suitable terminals on the unit.
• Make : KIRLOSKAR / CROMPTON / AEC / SIEMENS / NGEF (or eQUIVALENT)
