Voltage measurement and generator connection types
There are 4 voltage measurement ConnectionType (setpoint ConnectionType [3Ph4Wire /
3Ph3Wire / Split Ph / Mono Ph]) options, every type matches to corresponding generator connection
type.
The generator protections are evaluated from different voltages based on ConnectionType setting:
 3W 4Ph – Ph-Ph voltage
 3W 3Ph – Ph-Ph voltage
 Split Ph – Ph-N voltage
 Mono Ph – Ph-N voltage
ConnectionType: 3 Phase 4 Wires
