Temperature Indicator Testing & Replacement
Power transformers fitted with Winding Temperature Indicators (WTI) or Oil Temperature Indicators (OTI) can have their correct operation tested as part of a wider testing and commissioning project or as needed. Replacement instruments can also be supplied and fitted.
Modifications to transformers to accept temperature indicators can also be made. This can be to increase the protection on the transformer or to control additional cooling such as forced ventilation for fans, fitted to increase the rating of the transformers
