Standard features include:
- Voltage controlled/ restrained phase overcurrent
- Instantaneous phase and ground overcurrent protection for inadvertent energization
- Ground overcurrent
- 100% stator ground fault protection for high impedance grounded units
- Reverse power
- Loss of Field
- VT fuse loss
- Over and undervoltage and over and underfrequency
- Overexcitation
- Negative sequence overcurrent and overvoltage
- Sync check
- Breaker failure
- Logic timers, virtual control switches, metering, monitoring, fault recording, and multiple communications ports
- BESTCOMS GUI software available to aid in setup.
Both H1 and S1 cases are fully drawout, and the S1 includes a removable test paddle facilitating in case testing
