Product Description
MYR 10A IP55 Compact Transformer DC Winding Resistance Tester
Product Description
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime.By measuring a transformer's winding resistance from one HV transformer bushing to another, transformer resistance testing can reveal a great deal of information about the transformer. In addition to the obvious faulted transformer winding (i.e., an open winding or shorted turn), subtler problems can be detected. The DC current, in addition to flowing through the winding, also flows through the off-load ratio adjusting switch (DETC), the on-load ratio adjusting switch (on load tap changer or OLTC), as well as numerous welded and mechanical connections. Hence, the integrity of all these components can be verified with the use of transformer resistance test instruments. Applying DC test current through OLTC switches under transition (tap changes) validates proper make-before-break operation. From experience, it is known that the on load time changer has the greatest risk of misoperation as it operates within a transformer.
