What is the difference between Earth Fault protection &
as you are aware, in electrical engineering power
transformers or motor winding are connected in star-
undrounded or grounded,Delta connected.
Earth fault protection may be due to capacitaive
circulating current,flowing through the body of equipment
to ground. In large generator,motor it may be 5-10A
unbalanced current flowing through Neutral to ground, and
also fault current sigle phase to ground,double phase to
ground,or three phase to ground.these are severe
faluts.damages equipment severly.

hey guys i recently saw a long transmission line in which a sort of balloons in red and white color were hanging at each section.do u have any idea why are they kept for?
Why Nutral CT rating for Earth Fault Protection of Transformer neutral shall be 20% of Full load Current of Transformer
OUR METER READER TAKE READING OF INDUSTRIAL CONSUMER.THEY ALWAYS ASK HOW TO INCREASE POWER FACTOR FROM 60% TO 99 % TO AVOID PENALTY OF POWER FACTOR.
How to select the rating of the Transformer?

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?
