Transformers In a power or distribution transformer about 10 per cent end turns are heavily insulated to reflect the line surge and save the winding of a transformer from damage to absorb the line surge voltage and save the winding of transformer from damage to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns None of these to reflect the line surge and save the winding of a transformer from damage to absorb the line surge voltage and save the winding of transformer from damage to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns None of these ANSWER DOWNLOAD EXAMIANS APP
Transformers In case of 3-phase induction motors, plugging means interchanging two supply phases for quick stopping starting the motor on load which is more than the rated load locking of rotor due to harmonics pulling the motor directly on line without a starter interchanging two supply phases for quick stopping starting the motor on load which is more than the rated load locking of rotor due to harmonics pulling the motor directly on line without a starter ANSWER DOWNLOAD EXAMIANS APP
