Together with a temperature sensor, the EPT202 device from
the MTeC® series indicates the oil and winding temperature
of oil-insulated transformers, reactors or on-load
tap-changers. The device can be used to control the individu-
al cooling stages based on load and temperature and, in
emergencies, shut down the entire transformer.
Before commissioning the device, it is essential to read and
adhere to the limit values for the application specified on the
nameplate and operating instructions.
