| 4.12.1.1 DG electricity system
The generator adopts digital integrated relay protection system for monitoring and protection.
A DMR362 digital integrated relay is installed on generator switchgear, which is used for alternator protection, switch control, monitoring, measuring, display and SOE record.
The following functions are configured on the relay:
- Differential current
- Reverse power
- Instant trip current
- Voltage locked over current:
- Over current
- Over load
- Earth failure
- Over voltage
- Under voltage
- Low frequency
- Over frequency
