when there is a unbalace among the phases due to change in
load circulating current introduced this fault caurrent can
be eathed via neutral .

for stepdown distribution transformers the secondery side ie
lt side y-with nutrel earhto be connected because of load
side the current is not zero ie varying.hence we r connected
y-with nutrel earh......... finally this because of stand by
earth fault in load sideie secondery side..

We use ungrounded DC system (220V/110V) for control and protection system in substations etc. Suppose we have long 2 core DC cables running from our DCDB in control room to the load (length of around 2 to 3 km). Do we need to protect these long DC cables from earth leakages or not? If yes how?
