THREE TERMINALS OF MEGGERS ARE = GROUND, EARTH, LINE

THREE TERMINAL USE = GROUND & LINE USE FOR CHECKING
RESISTANCE BETWEEN GROUND AND LINE

EARTH AND LINE ARE USE FOR CHECKING RESISTANCE BETWEEN TWO
TERMINALS ONE WINDING

Answer / baljeetsingh

meggers have only two terminals and three terminal device
mentioned by u is earth resistance tester.
meggers are used to check insulation value of any equipment
wrt earth which should be highest possible in m ohms and
earth resistance are used to check the effectiveness of
earth pits and their resistancce which should be lowest
possible in ohms

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
