What is OLTC in a transformer, specify its fuction.

Answer Posted / manoj kumar behera

OLTC means ONLOAD TAP CHANGER UT CAN BE OPERATED MANUALLY
OR AUTOMETICALLY. TO OPERATE IT IN MANUAL MODE THERE HAVE
CERATIN CONNECTIONS THAT WE HAVE TO GIVE THAT WILL VARY
DEPENDS UPON THE OLTC MAKE WHILE WE WANT TO OPERATE IT IN
AUTOMETIC MODE WE HAVE TO CONNECT IT TO A RTCC PANEL THAT
IS REMOTE TAP CHANGER CIRCUIT.
THE FUNCTION OF OLTC IS TO CHANGE THE TAPS OF A
TRANSFORMER .THAT IS IT ARRANGE CONSTANT OUTPUT ON L.V.
SIDE.
