4.2 Function description
Depending on the device version, the pointer thermometer measures the oil
temperature or determines the winding temperature in power transformers,
distribution transformers or reactors. The temperature sensor of the pointer
thermometer is located in the thermometer pocket mounted in the trans-
former tank. The measured value is displayed directly on the pointer ther-
mometer.
