WHAT IS OLTC OF TRANSFORMER? WHERE IS ITS USED EITHER ON PRIMARY OR SECONDARY SIDE OF TRANSFORMER?..

Answer / mayank

OLTC means...ON LOAD TAP CHANGER. It is provided on the HV
side of the transformer. On HV side as the current is less
we can easily( not that easily..) switch over to different
voltage levels thus producing minimum chances of arc
production. While on the LV side as the current is very
large On load tap changing almost becomes impossible.

Answer / kedar

OLTC means On Load tap changer of transformer used for reliability of power supply.
OLTC can be on either side of transformer.It depends whether the transformer is step up or step down. For Step Up transformer it will be on Secondary side(H.T) while for Step down it will be on Primary side(H.T) of the transfomer.

We have received supplies of the ordered material. payments against the supplies also released. Where ST paid 4% against form C. Meanwhile it has been observed that 25% of material supplied was defective. Please suggest whether the issuance of C form from our side would be stopped till settlement of liabilities.
