REG-DA is an automatic voltage regulation system designed for transformers equipped with On-Load Tap Changers (OLTC). It continuously measures and regulates the voltage and automatically adjusts the tap position to maintain the voltage within specified limits, while also monitoring the condition of the transformer and OLTC.

Supports monitoring of Hot-Spot Temperature and Transformer Loss-of-Life, as well as cooling system control. Supports Parallel Operation of multiple transformers through ELAN Bus and ParaGramer, and connects to SCADA systems using standard communication protocols such as IEC 61850 and IEC 60870-5-104.

Key Features: Automatic voltage and OLTC control / Continuous transformer and OLTC monitoring / Hot-Spot Temperature and Loss-of-Life monitoring / Supports Parallel Operation of transformers / Data recording and analysis / SCADA, IEC 61850 and other standard communication protocols / Supports Remote I/O and communication-based data acquisition, reducing the need for CT/VT cabling in certain configurations
