Abstract

1470692 Measuring transformer temperature electrically SKODA OBOROVY PODNIK 20 May 1974 [18 June 1973] 22450/74 Heading G1N Apparatus for measuring the temperature of a transformer winding 7 includes a sensor 3 such as a thermistor or thermocouple which is soldered directly to the conductor of the winding or inserted between parallel conductors of the winding. A power supply source is formed by an induction coil 2 and a radio transmitter 1 signals by way of antennae 4, 9 the temperature to a receiver 10.
