RTCC means Remote Tap Changer Control Panel which is a programmable device to control the output of the transformer through OLTC unit fitted in the transformer through control cables. It is a panel consisting of the AVR (automatic voltage regulator), display for tap position, voltage, LEDs for raise and lower of taps relays, selector switches for auto manual selection, etc. ln Auto mode the voltage is controlled by the AVR. In manual mode, the operator can increase/decrease the voltage by changing the taps manually through the push button in the RTCC.
- Programmable device to control the output of transformer by changing tap position.
- Tap position Indication
- Visibility of voltage of different Tap Position
- Tap position changing by both automatic and manually through Automatic voltage regulator
