The LTM R controller measures ground currents and provides values in Amperes and as a percentage of
FLCmin.
The internal ground current (IgrΣ) is calculated by the LTM R controller from the 3 line currents
measured by the load current transformers. It reports 0 when the current falls below 10 % of FLCmin.
The external ground current (Igr) is measured by the external ground current transformer connected to
Z1 and Z2 terminals.
For configurable parameter check below attachment.
