What core magnetic balance test of transformer?
How to do this test in a three phase Star delta (star-LV,
Delta-HV) transformer?
How to measure and where to measure?
thanks and regards

MAGNETIC BALANCE TEST
THIS TEST IS SIMILAR AS OPEN CIRCUIT TEST
PROVIDE THE SINGLE PHASE SUPPLY (BELOW 230 V)TO THE STAR
SIDE OF THE TRANSFORMER BY PROPERLY CONNECTED
1.GIVE SUPPLY TO 2N AND 2U AND THEN MEASURE THE VOLTAGE ON
2N2V AND 2N2W
(i.e)IT SATISFIED THE CONDITION
2U2N=2V2N+2W2N
SIMILARILY THE TEST CONDUCTED ON OTHER TWO PHASES BY SAME
MEANS
(NOTE: NO ONE SHOULD BE STAND ON HIGH VOLTAGE SIDE WHILE
TESTING )

For a three phase induction motor, what will be the effect on motor if the neutral of the system is shifted to say 20 deg.?
In AC if the direction of current keeps reversing every half cycle, how does it propogate through the transmission lines?

1.Z transform always lies around ? a) origin b) pole c) zero d) z=1. Multiples Mcqs which is bother me can’t find answers on internet. Some help required with little explanation . Note: this is not homework or related to any test. Thanks
if we have a industrial load of 400 kilowatts with 415 volt AC then how much total harmonic distortion (thd%) should be acceptable for steady power system.
A 10 MVA, 66KV, 50Hz, Y-connected 3-phase alternator has synchronous reactance of 0.635 Ù. It is working at full load at 0.8 lagging p.f. condition. Find torque angle, neglect armature resistance.

Dear all: Recently we got a question about Interface between PMS and SAP-PM.once we got a update message from PMS.we should set the deletional flag for functional location in SAP system.Is there any FM or BAPI to use?There are only functional location create and change provided by SAP.
