OLTC MEANS ON LOAD TAP CHANGER. THE LOCATION OF OLTC IN
TRANSFORMER IS IN HV WDG. THE TAPPING IS TAKEN FROM HV WDG
B COZ
1. IN HV WDG NO. OF TURNS ARE MORE. SO,VOLTAGE REGULATION
IS GOOD.
2. THE HV WDG IS NEARER TO THE CORE. SO, THE TAPPING IS
POSSIBLE.
3. IN HV WDG CURRENT CARRING CAPACITY IS LESS THAN LV WDG.

THE FUNCTION OF OLTC IS TO GIVE CONSTANNT VOLLTAGE TO
SECONDARY WDG.

PLEASE GIVE ANY ANSWER THEN WELCOME
