RTCC Panel

An RTCC Panel (Remote Tap Changer Control Panel) is a vital control unit used to operate and monitor the on-load tap changer (OLTC) of a power transformer remotely. Its main function is to maintain a stable and constant output voltage by adjusting the transformer’s tap positions in response to voltage fluctuations on the primary side. RTCC panels are essential in power distribution systems where voltage regulation is critical for operational efficiency and equipment protection.

The panel continuously monitors the secondary voltage of the transformer. When the voltage deviates from the pre-set range—either too high or too low—it sends an automatic command to the OLTC motor to raise or lower the tap position accordingly. This tap-shifting action helps compensate for input voltage variations, ensuring a steady voltage output. Operators can also switch to manual mode for local control during maintenance or special conditions.

RTCC panels are widely used in power substations, utility transformer yards, industrial plants, and facilities with high-voltage transformers where remote voltage regulation and real-time monitoring are necessary. At Amtech Power, our RTCC panels are designed for seamless integration with OLTC-equipped transformers, offering precise voltage control, automatic operation, and built-in protections—ensuring efficient energy distribution and extended transformer life.
