l Reverse connection detect unit to prevent the high voltage injected to operator

l Over current protection unit integrated in software and hardware

l Upload the test results to PC by RS232 and make word report by software

Specifications:

Benefits:

The test power supply is generated by the internal power amplifier of the tester, and the waveform distortion rate is less than 0.5% and is not affected by the quality of power supply.

Automatic voltage regulation, with automatic protection functions such as transformer reverse connection, over-current, etc., to avoid damage to the instrument due to incorrect operation.

It can be used for power transformer, CT and PT ratio detection.

Convenient standard transformation ratio setting template, don’t need to manually calculate the standard transformation ratio value.

GDBC-901 is very light, only 20KG. It’s easy to carry. It’s suitable for field test.
