Transformer Oil Role in Transformer Protection

Here we are writing an article to inform and to make aware about how does transformer oil plays a role in transformer protection. Transformer mainly depends on oil volume it contains. Therefore it is highly important to check transformer oil quality after regular intervals, so that if contamination is found in oil like grease, dissolved gas, moisture content etc it can be changed easily with fresh oil. Tran former oil protects transformer from any type of failure thus keeping it secured. To know more information visit http://powerlinkoil.com/
