- Interface to special protection and operational tripping schemes
- Communications using standard grid protocols including IEC61850, IEC60870-5-101, IEC60870-5-104
- Metering including AC/DC voltage/current, active/reactive power, harmonics and other parameters
- Transient fault recording and cable monitoring
- Converter cooling and valve hall fire detection
- Auxiliary power supply and power supply supervision
