Abstract

See full text

An apparatus includes a temperature sensor configured to measure a temperature of a dry-type transformer, and the temperature sensor is arranged on or proximate a conductor of the dry-type transformer and is covered by an insulating layer of the conductor. The apparatus further includes a passive wireless communication module configured to transmit the measured temperature to a reader. The temperature of the dry-type transformer can be measured accurately, thereby improving the reliability and safety of the dry-type transformer. Accordingly, temperature measurement for the dry-type transformer can work appropriately in a cost-effective and efficient way.
