AQ-T215 is a voltage regulating IED. It comes with current-based and voltage-based protection functions, which makes the relay suitable for combined transformer voltage regulation and back-up protection. The transformer monitoring module is included as a standard feature, and it provides statistical information for preventive maintenance purposes. AQ-T215 communicates using various protocols, including the IEC 61850 substation communication standard.
- Automatic/manual voltage regulating (AVR)
- Transformer back-up protection
- Overloading and through fault statistics for preventive maintenance
