What will happend in oltc when voltage comes high?
If the OLTC is on the secondary, and the secondary voltage is high, the OLTC will tap down, which will lower the voltage. Typical range of OLTC is +/- 10%. The primary may also have multiple taps so the OLTC can be set at '0' under normal conditions.
Why oltc is situated on primary side of traformer?
oltc is situated on primary side of transformer because by primary side we can obtain fine voltage change by tapping with low current flow through it.
What main by OCTC and OLTC in the transformer?
OCTC means off circuit tap changer (off load tap changer) and OLTC means on load tap changer. in octc we can change the tap position while the transformer is in off condition only. we can not change the tap position of octc in charged condtion of the transformer. the tap position of octc can be change in deenrgise condion of transformer only means if you nwant to chang the tap position firstly you will have to deenrgise the power transformer then you can change the tap position of octc.while in oltc we can change the tap position of OLTC in charged condition of power transformer. This is the basic diffirence between OCTC and OLTC.generally the OCTC used in single phase generating transformer (G.T.Power Transformer) and OLTC used in three phase powwer transformers like standby transformer and auto transformer in power plants and switch yards. for any other question please mail me at (ashu_uit2007@yahoo.co.in )
What does OSR do in transformer?
