Benefits and Intelligence of Transformer Gas Relays

The advantages of transformer gas relay (gas relay) can be summarized as the following five core advantages: 1. High sensitivity, early warning of faults It can detect minor turn-to-turn short circuits, partial overheating of the iron core, degradation of the insulating oil and other faults, which have a small current and are often not recognized by differential protection. When the gas in the oil slowly accumulates...
