C.3.3 Line resistance and prospective short circuit current
Measured resistance represents Line-Line resistance (R
L1-L2
). Nominal system voltage
for calculation of I
PSC
is set to 110 V.
Nominal system voltage range for line resistance measurement is 90 V to 121 V. If input
voltage is out of range it is displayed on terminal voltage monitor, together with the
indicator of disabled test .
C.3.4 Fault loop resistance and prospective fault current
The definition of the nominal system voltage for calculating the I
PFC
changes to:
 55 V for single-phase centre-tap system selected,
 63 V for three-phase system selected.
Tests can be carried out for both combination L1-PE and L2-PE. Each individual test
result is accompanied with appropriate indication.
Nominal input voltages are:
Nominal input voltage U
N
Voltage range
Single-phase 55 V system
(44 V  U  61 V),
Three-phase 63 V system
(56 V  U  70 V),
If an input voltage is out of range, it is displayed on terminal voltage monitor together
with the indicator of disabled test .
