Product details

1.?Production brief

Winding temperature is a very important measurand in power transformers, which defines the condition, load capacity and operating life of transformers. Every operator requires the accurate on-line measurement of the transformer winding hot spot temperature, as the ageing of the transformer insulation and the winding hot spot temperature during operation are interrelated, thus he operator can schedule short term and emergency overloading of the transformer above the rating on its name plate without compromising the estimated life of the transformer. Thus, the accurate measurement of the winding hot spot temperature is essential for the best use of the transformer.

Herch Opto’s innovative fiber optic temperature sensors do just that with maximum durability. Its HQ-E116 type fiber optic temperature monitoring systems allows upto 16 sensors which can be used to measure and monitor transformer top oil, bushing, winding and magnetic core temperature. The sensors can be positioned onto the measurement points inside the transformer and work reliably over 30 years. ?Optic fibers transmit the measurements optically, eliminating the negative influence of both electrical and electromagnetic interference.
