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

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
