Transformers In a power or distribution transformer about 10 per cent end turns are heavily insulated to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns to absorb the line surge voltage and save the winding of transformer from damage None of these to reflect the line surge and save the winding of a transformer from damage to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns to absorb the line surge voltage and save the winding of transformer from damage None of these to reflect the line surge and save the winding of a transformer from damage ANSWER DOWNLOAD EXAMIANS APP
Transformers The efficiency of a transformer, under heavy loads, is comparatively low because copper loss becomes high in proportion to the output iron loss is increased considerably voltage drop both in primary and secondary becomes large secondary output is much less as compared to primary input copper loss becomes high in proportion to the output iron loss is increased considerably voltage drop both in primary and secondary becomes large secondary output is much less as compared to primary input ANSWER DOWNLOAD EXAMIANS APP
