The increase in demand for energy has made us enhance the power transformation capacity as well as reactive power compensation requirement. Reliability and availability of important assets play an important role in the smooth operation of a power system. The transformers are vital and expensive assets in a power system hence it is important to …

In our earlier blog on the transformer, we shared our views on how to detect possible core & winding damage using the Transformer Turns Ratio Meter. The oil which acts as the insulating medium is one of the reasons for internal transformer failure. The oil decomposes mainly due to Thermal, electrical & chemical stress due …

Power transformers are one of the most expensive and critical assets of the power sector. In this blog, we will discuss [1] principles of winding resistance measurement, a common transformer test prescribed in various standards such as IEEE C57.12.90-2006 Clause 5, IEC 60076-1 Clause 10.2, IS 2026-1 Clause 10.2; [2] OLTC condition analysis; and [3] …
