Static Electrification in large core Mark III transformers
(OP)
Is there anyone that has experience with Static Electrification in large transformers? I am Looking for proceedures in oil replacement to minimize the risks.





RE: Static Electrification in large core Mark III transformers
Large W Shell form transformers are most susceptible since they have high flow velocities. The charge builds up when high velocity cold oil is flowing. Procedure is to run pumps for 24 hours to warm oil before energizing the transformer. Perhaps more if extremely cold weather.
