Transformers : Load Tap Changers
LTC’s are attributed to more transformer failures than any other sub-system associated with the transformer. A normal signature for an LTC is included in the severity criteria for transformers and their sub-systems. Acquiring data from an operating LTC is imperative to determining the health of this system. Oil analysis and wave shape analysis of the arc during a step change aid in the CA of the LTC.
