KVA Process Transformers Pvt. Ltd.

These OLTC Fitted Transformers are avaiable in three types :

1. If the variation of input high voltage is within 15-20% of the rated voltage ; the step-down transformer can be provided with ON LOAD TAP CHANGER (OLTC). The voltage sensing relay of the OLTC panel choose the suitable tap automatically resulting the regulated output voltage.
2. If the variation of input high voltage is more then 20% of the rated voltage, the OLTC is attached with a star connected high voltage auto transformer having suitable taps in addition of normal step down transformer and placed in the same cabinet. The Voltage sensing relay of the OLTC panel chooses the suitable tap automatically and regulated HT voltage (+/1-%) from the auto tranformer is fed to the step down transformer.
3. If normal step-down transformer had already been installed or if the capacity of the step-down transformer is very high (more than 2 MVA); the regulator is made in separate cabinet. This types of regulator consists of an auto-transformer with OLTC Regulated HT voltage from the regulator is fed to the step-down transformer.
