Temperature Controller for Dry Type Transformer

---

The temperature controller for dry type transformer (Referred to as temperature controller) is an intelligent controller designed specially for safe operation of dry transformer. The temperature controller features adoption of single chip computer technology and utilization of the three platinum thermo-resistors embedded in the 3-phase winding of the dry transformer for detection and display of temperature rise of the transformer windings. It can start or stop the cooling fan automatically for forced air cooling of windings and control over-temperature alarm and over-temperature tripping output so that the transformer will be operated safely.
