MEASUREMENT SETUP
Fix Dem. Period 30 minutes 1 to 99 minutes step 1 minute
This setting defines the length of the fixed demand window.
Roll Sub Period 30 minutes 1 to 99 minutes step 1 minute
These two settings are used to set the length of the window used for the calculation of
rolling demand quantities.
Num. Sub Periods 1 1 to 15 step 1
This setting is used to set the resolution of the rolling sub window.
Distance Unit* km km/miles
This setting is used to select the unit of distance for fault location purposes, note that the
length of the line is preserved when converting from km to miles and vice versa.
Fault Location* Distance Distance/Ohms/% of Line
The calculated fault location can be displayed using one of several options selected using
this setting.
Remote2 Values Primary Primary or Secondary
The setting defines whether the values measured via the 2
nd
Rear Communication port are
displayed in primary or secondary terms.
1.4.8 Measurement display quantities
There are four Measurement columns available in the relay for viewing of measurement
quantities. These can also be viewed with MiCOM S1 Studio (see MiCOM Px40 - Monitoring
section of the MiCOM S1 Studio User Manual) and are shown below:
