Transformer Temperature Monitoring Devices

Use a powered monitoring device when an oil-immersed transformer project requires digital temperature, level or pressure values at a remote terminal.

Direct answer. A transformer temperature monitoring device uses powered sensing and electronics to acquire one or more operating variables and transmit them to a compatible display, RTU, PLC or supervisory system. It differs from a self-contained mechanical OTI or WTI.

Review model functions, outputs, installation interfaces and current document requirements before requesting a quotation.

How to Select a Transformer Temperature Monitoring Device

Define the measured variables, sensor arrangement, DC supply, analog or RS485 interface, protocol, scaling and alarm responsibility. Confirm tank mounting, oil compatibility, enclosure protection, receiving terminal and commissioning method.

Define the transformer measurement and control functions

Top-oil temperature, traditionally simulated winding temperature and direct winding hot-spot temperature are different values. Define the required local display, cooling stages, alarm or trip contacts, remote output and receiving equipment before comparing suffixes.

Provide complete mechanical and electrical interfaces

Send the transformer type, existing model, measuring range, contact duty, Pt100 or 4-20 mA requirement, supply, capillary length, bulb, thread, mounting dimensions, quantity and destination country. Replacement projects should include nameplate, terminal and installation photographs.

Control the final model specification

BWY, BWY2, BWR and BWR2 family names can cover several contact and output configurations. Confirm the complete model code against the current datasheet, outline drawing and terminal diagram before purchase.

For system integration, review substation remote transformer temperature monitoring and the transformer temperature controller wiring guide.
