PTG720A PT Inductive Voltage Withstand Tester


PTG720A PT Inductive Voltage Withstand Tester
PTG720A used for testing voltage transformer inductive voltage withstand, excitation characteristic, ratio and polarity.
l Performing voltage transformer primary side inductive voltage withstand. Automatic regulate external compensating inductor.
l Using wattless power feedback technique, output power can up to 9kVA at the condition of power factor 0.6.
l Measuring voltage transformer excitation characteristic.
l Measuring electromagnetic voltage transformer ratio and polarity.
l The screen shows testing result and curve clearly.
l Thermal printer can print results and curve.
l Checking the connecting cable automatically. Wrong connecting warning instructions.
l Built-in large memory storage can stored 3000 winding test values, loss of power without loss of values.
l Using U-disk transfer the values to PC, and generate report.
l Use a U-disk to update software.
