Thank you very much for the reply.
My worry is, if for any reason the transformer deluge system is beginning to operate without to disconnect timely the power from the transformer and the possible flashover risk. (the transformer prime voltage is 150kV).
For this reason, I am wondering if is...
Hi to all!
I am wondering about the needed quality of the water which is used on outdoor oil-transformers fire fighting deluge systems. Just poor potable water is good enough or is needed something special like demi water with low conductivity or something else?
Thanks in advance!
I would be grateful if you could help me to find any Technical Papers about the selection of an earthing method for a medium voltage system (6 kV).It is an industrial application and I want to select between an unearthed system and a high impedance system.
