Real Time Monitoring
Instantaneous Current Monitoring
The real time monitoring features are automatically updated following a successful connection.
Now: It is the Root Mean Square current (RMS) calculated every one second.
Last hour: It is average of RMS current calculated for every one second and averaged over 3600 sec (1h=60x60) i.e., an hour. The
Last hour average current is updated every 10 sec only for the very first one hour when the recloser sees the current since it would
not see the 3600 entries for times less than one hour.
Peak: It is the mean square current seen for every one second interval which is always compared against the previous mean square
current and the greater of the two is displayed.
The peak and the last hour rolling average values can be reset using the appropriate reset buttons for each.
