How to detect oil immersed power transformers? If you have oil immersed power transformers and related products that need to be sold, the relevant parties need you to provide an oil immersed power transformer testing report. If you are unsure of the testing items and standards required for the oil immersed power transformer testing report, BAIJIAN can help you solve these problems Oil immersed transformers of 1000kVA and above must be equipped with outdoor signal thermometers and can be connected to remote signals. 800kVA and above oil immersed transformers should be equipped with gas relays and pressure protection devices. Oil immersed transformers below 800kVA can also be equipped with gas relays according to usage requirements and in consultation with the manufacturer. Dry type transformers should be equipped with temperature measurement devices according to the manufacturer's regulations, generally for transformers of 630kVA and above
