What is OLTC in a transformer, specify its fuction.

Answer Posted / sabale.dnyaneshwar@gmail.com

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
ANY DOUBT E MAIL ME. ON SABALE.DNYANESHWAR@GMAIL.COM

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
