What will happen if apply dc source for power transformer..

Answer / natha

if dc is applied,the nature is non sinusoidal so no flux linkage.this leaves us with simple v= i*r type situation(referring to basic equations).in transformers the winding resistance is low.if 220v dc is applied and resistance of winding is 0.5 then current i=220/.5 which is high value shorting the winding and eventually burning it out.
but why the hell apply dc to transformers in first place

Answer / k.prakashchandra

Tr is an ac machine.If dc is applied ,the current will be
equal to voltage divided by dc resistance as inductance and
back emf are absent.There will not any output in the secondary.

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?
