Transformer oil contains hydrogen
Thread Content
The transformer oil contains hydrogen, and the cause has not been identified. Sometimes, 5 to 6 batches of oil contain hydrogen, while the 7th batch does not. Why does this happen? Under what conditions is hydrogen generated? Those who know about this, please help explain it
It’s possible that the liquid level in the gas-liquid separation tank is too high, that the load on the system is too great, that there is a leak in the heat exchanger or other equipment, or that hydrogen has entered the nitrogen pipeline
