How can we find out earth leakage,(shock)in side the house?..
(with out ELCB)
Answers were Sorted based on User's Feedback
We can find it simply with the help of a testlamp.
(1)Disconnect the earth line from earth plate or earth pipe.
(2)Connect one wire of the testlamp to the neutral.
(3)Touch the second wire of the testlamp to the doubted
areas.
(4)Continue the test by changing the two leads of the
testlamp.

Answer / pillay
similar to answer 1 instead of a test lamp connect a volt
meter in between the equipment frame and earth .good non
leaking equipment would have no voltage between them. A
higher voltage means higher leakage. pls dont forget to
connect back the earth connection after your test.

How much allowable difference current between on three phases Dear sir, We have a 1870 KW HT motor, 11 Kv supply,FLA-120A,2870 rpm,2-pole squirrel cage induction Motor.And stator is connected in star connection with Liquid resistance stater to limit the starting current.It has coupled with Centrifugal air compressor.My question is it is loading 73% of FLA taking R-phase 86.7 A, Y-phase-85.4A,B-phase- 78.3A.why the B phase current is that much of difference.Is it allowable, or any one tell me how much allowable current.If any method to calculate.
