If we supply DC to primary of transformer no emf is induced
in primary side(Accordibg to Faraday laws).It means whole
applied voltage is droped in primary winding resistance
which is very low.So high current will flow through the
primary winding which ultimately burn the primary winding.

Can we check ELCB constantly from R1 to R8 phase in 1 no DB?

Thank,s and Regard,s. Muhammed Ikram.
