Hi,

Wondering if anyone is aware on if a single phase open circuit fault on an overhead line feeding the HV side of a Ynyn transformer, 33/11kV for example, can be detected by protection on the 11kV side of the transformer?

Would the 11kV side current distribution be able to identify the condition?

Thanks
