4.2.1 System
CT ratio
Load current transformers transfer ratio(Primary current/Secondary current) value must be entered to
this parameter.
Example:
If Current Transformer Primary=500A and Current Transformer Secondary=5A, Current Transformer
Ratio should be entered CT Primary/CT Secondary=100.
PT ratio
Defines the scaling factor applied to voltage readout and associated fault conditions.
This PT ratio is for additional voltage transformers mounted the unit.
CT location
Generator: The CTs are located to the generator side, so will show only generator load.
Load: The CTs are located to the load side, so will show generator or mains load provided by supply.
