Product Q&A
Q:Do I need to disconnect the transformer from the power system?
A:
Yes, the transformer must be completely de-energized and isolated from the grid. All external connections (bushings, cables, busbars) should be disconnected for safety and accurate measurement.
Q:What accuracy can I expect from a quality tester?
A:
Reputable testers comply with IEC 60076-1, IEEE C57.12.90, and GB/T 1094, ensuring your test results are accepted globally for commissioning, maintenance records, and warranty claims.
Q:What standards do these testers comply with?
A:
Yes, standard ratio testers can test any tap position manually. Multi-function versions add automatic tap changer sequencing, but even basic models allow you to move the tap changer and re-test each position individually.
