Transformer resistance tester

LYZZC-IIITransformer resistance testerPrecautions

1It is necessary to wait for the discharge to end and the alarm sound to stop before disconnecting the wire, otherwise it is dangerous.

2When measuring no-load tap changers, it is necessary to reset the discharge before reversing the tap changer, and only switch the tap changer after the alarm sound stops.

3. When selecting the current, reference should be made to the measurement range in the technical specifications column. When exceeding the range, due to the current not reaching the preset value,Transformer resistance testerAlways in the "charging" state, press the reset button to reset the instrument and select a smaller current gear again. When the range is insufficient, it displays "current too small". When these two states occur, confirm the range and select a larger current for testing.

4After the test is completed, press the "reset" button to disconnect the instrument power supply from the winding, discharge at the same time, sound an alarm, and the ammeter returns to zero. At this time, the display screen returns to the initial listening state. After the discharge sound is completed, the wiring can be reconnected for the next measurement or the test wire and power wire can be removed to end the measurement.
