Maintenance power of transformer tester

The magnetic flux of the transformer tester's iron core is related to the applied voltage. Transformer testers should be kept away from strong electric fields, magnetic fields, and high-frequency equipment. The smaller the interference of the power supply, the better. It is advisable to choose lighting lines. Assuming that the power interference is still significant, the instrument can be powered by a communication purification power supply with a capacity greater than 200VA.

When working on the transformer resistance tester, assuming that the LCD screen appears disorderly and there is no response when pressing all buttons, perhaps the measured value is far from the actual value. Please press the reset button, or turn off the power, and then operate from scratch. When the transformer tester is working, if the LCD screen displays disorderly and all buttons are pressed without any response, perhaps the measured value is far from the actual value. Please press the reset button, or turn off the power, and then operate from scratch.

After the winding undergoes deformation, it is still normal for enterprises to carry out teaching work, which simply presents network faults. This is because after the winding undergoes deformation, the mechanical equipment performance requirements of the winding will continuously decrease. When the winding is again subjected to the impact of short-circuit current, it is highly likely that it cannot withstand the huge impact of electricity, leading to damage incidents.

After the deformation of the winding occurs, it may appear that the insulation material performance of the transformer tester has undergone significant changes, which may also lead to a partial discharge situation in the transformer tester. In this social situation, if the economic situation of the transformer tester is not timely solved.

Under long-term operation, the selection of partial discharge conditions will gradually increase the area of insulation damage, and ultimately the result may be the occurrence of insulation breakdown in transformer testers. The design and production of transformer testers can easily lead to malfunctions if they do not have good maintenance skills and craftsmanship during operation.
