Magnetic balance test preformed to find the condition of core and international fault and magnetic test A/C supply is sufficient on HV side not required DC source... And while testing we try avaoid DC supply apply more time it will affect the AC system performance...
nalla understand achu super.....
Your video is useful, try to make more videos
Similarly we have conduct this for for LV side ?? Or only HT side of the transformer
Test should perform on HV side only
Why we find magnetic balance disturbed when it's measured after d.c injection?
How d.c supply disturb the magnetic balance of healthy x'mer?

Sir LT winding is it open or not
In test during
Tell sir i have a doubt
We should not make short in LT side during the magnetic balance test.
@@manibalan7524 thanks sir
Can you please confirm me measureings site primary or secondary
Test should be carried by primary side of winding.
One small doubt bro how to do same for star side
Need 230v or 440v
@@atharpasha3013 440v bacause phase to phase voltage
Magnetic balance test sufficient only to HV side....
Star side not required if transformer is star to star that condition we will measure neutral voltage also...
@@atharpasha3013 phase to pahse
You are using 3 phase voltage but only r y where is b phase
Instead of r and y same procedure we can use the r and b
We are using only phase to pahse voltage only
No problem any two phases
