What is RTCC panel RTCC?

What is RTCC panel RTCC?

RTCC Panel RTCC is “ Remote Tap Changer Control” Which is a programmable device to control the output of the transformer through OLTC unit fitted in the transformer through control cables. The desired Voltage will be achieved accordingly by controlling the OLTC with respect to the tap position through RTCC systems.

How to control the voltage of RTCC?

In 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. Normally RTCC panel will be installed in Main panel room and will be connected to OLTC (On load tap changer) of the transformer through control cable.

What is RTCC&AVR remote tap changer control panel?

RTCC & AVR REMOTE TAP CHANGER CONTROL PANEL RTCC is “Remote Tap Changer Control “which is a Programmable device to control the output of the transformer through OLTC unit fitted in the transformer through control cables. The desired voltage will be achieved accordingly by controlling the OLTC with respect to the tap position through RTCC system.

What is RTCC and LCP?

The RTCC sends signals to LCP and LCP in turn rotates the motor as per the signals received from the RTCC. Automatic OLTC Panel consists of a LCP & a RTCC. System uses an AVR (AVR-MA9) to sense the LV voltage and a comparator circuit to compare the sensing voltage with a preset value.
