Hi cranky108,
Thank you for your responce.
Transformer impedance is 50.5 ohm, CT rating: secondary rating in our country used 1 amp and its working principle is the same with 5 amp. When a single phase short circuit fault happens, the short circuit current in the 35kV busbar is 1400 amps, after...
Hello Tip DS,
Thank you for your response and for finding my question interesting. It seems we're still awaiting input from subject matter experts in this area. In the meantime, I've been doing some further research to better understand the considerations for selecting the CT ratio for an...
Hello fellow engineers,
I'm currently working on a wind farm generator setup where we have an earthing transformer with a capacity of 1000kVA connected to a busbar operating at a voltage level of 35kV. The Neutral Earthing Resistor (NER) has a resistance of 50.5 ohms. My objective is to...
