AQ-T216 is a transformer protection IED with a sophisticated and easy-to-use differential protection function. The relay provides overcurrent protection for both LV and HV side, earth fault protection, negative sequence overcurrent protection as well as two independent instances of restricted earth fault protection. Additionally, AQ-T216 can be applied to generator and motor differential protection. AQ-T216 communicates using various protocols, including the IEC 61850 substation communication standard.
- Both pre-defined and custom connection group selection
- 2nd and 5th harmonic blocking
- Automatic verification for the connection group and nominal value settings
- Overloading and through fault statistics for preventive maintenance.
