The transformer laminations are insulated from each other by thin coat of varnish.
Answer : In a power or distribution transformer about 10 percent end turns are heavily insulated to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns.
Answer : The thickness of laminations used in a transformer is usually 0.4 mm to 0.5 mm.
Answer : Silicon steel used in laminations mainly reduces hysteresis loss.
Description : In DC generators lamination core are generally made of?
Answer : In DC generators lamination core are generally made of silicon steel.
Description : Even at no-load, a transformer draws current from the mains. Why?
