Question { JSL, 11280 }

how induction motor starts?


Answer

in induction motor power is not fed to rotor but it is
induced in the rotor through electromagnetic induction.
its various starting methods are:
1. dol direct on line starting
2. star delta starter
3. through variable frequency drives
4. restance starter
5. auto transformer starter
6. series reactor starter

Question { 7211 }

can you explain the rms value in simple words....


Answer

rms is root mean square
it is noted in ac votage or power or current
it is always less tggan the peak value
if one work is done by dc voltage say heat producing
then the same heat is produced by the ac voltage
the ac voltage is known as rns value

Is This Answer Correct ?    2 Yes 0 No

Question { 4834 }

WHAT IS THE FUNCTION OF RCCB


Answer

rccb basicaly works when there is sm difference in i/p and
o/p current
it is an advanced version of elcb
mostly it is used in 3 no.s i.e. 1 for each phase
for single phase supply rcbo is used

it provides protection from earth leakage
