Transformer protection

ZIEHL temperature relays protect dry transformers from overheating by monitoring the winding and core temperature with PTC thermistor sensors or Pt 100 (RTD) sensors. Integrated controls switch on fans for cooling if required, thus ensuring reliable and error free operation.

Application examples

Dry type transformers in office buildings

Dry type transformers in shipbuilding

Dry type transformers in industrial furnaces

Dry type transformers in offshore and onshore wind turbines
