Answer / bijoy kumar soni

impedence of a transformer is defined by the vectorials sum
of resistance, capacitance and inductance of the core of
primary winding

Answer / gtr

resistance offered to the flow of current in the
transformer ckt which gives rise to thermal heating. for
efficent functioning, impedance is kept as low as
possible .

We use MCCB not MCB for motor starters because MCCBs has capablity to drawout the motor starting current which is 5-6 times the full load current of motor for 1sec. Then why we use SDF in starter panel means MCC panels. Pls reply if any one knows this answer.
