Digital Tapchanger Control for transformers and regulators

The TCC300 is a dedicated controller for metering,

monitoring, and operational control of step-voltage load tap

changers. The TCC300 is a microprocessor-based package

suitable for substation transformers with on-load tap

changers. The TCC300 can be easily integrated to replace

electromechanical on-load tap changer controllers or for

new installations requiring state-of-the-art controllers.

The TCC300 provides reliable operation with expanding

capabilities such as means to address distributed

generation and cyber security requirements.
