Oil-immersed transformer applications

Transformer Temperature Monitoring Solutions

Define the thermal variable, operating decision, signal path and installation interface before selecting an OTI, WTI, BWY, BWR or digital monitoring device.

Application planning answer. A transformer temperature monitoring solution coordinates the field measurement, local indication, cooling contacts, alarm or trip outputs and remote data path. Product selection follows the transformer design and operating purpose.

What must be defined before selecting the monitoring system?

State whether the project needs transformer top-oil temperature, traditionally simulated winding temperature or another direct measurement. Then define the local display, cooling stages, alarm and trip philosophy, remote interface, receiving equipment and commissioning method.

Connect OTI and WTI values to the correct operating decision

An OTI follows top-oil temperature at a specified thermometer pocket. A WTI adds a load-current-related thermal simulation. Their contacts and remote tags should retain those identities so operators do not treat unlike values as the same temperature.

Use application pages to select a product path

After reviewing the application, compare transformer oil temperature indicators, transformer winding temperature indicators and remote monitoring devices.
