The following table lists available device configuration options.
Parameter Options Default Description
Basic Configuration
Wiring mode See Table below 4LN3 The wiring connection of the device
PT ratio 1 1.0-6500.0 1.0 The phase potential transformer’s
primary to secondary ratio
PT Ratio multiplier Ч1, Ч10 Ч1 PT Ratio
multiplication
factor. Used in
extra high voltage
networks to
accommodate the
PT ratio for 500 kV
and higher
networks.
CT primary current 1-20,000 A 5 A The primary rating of the phase
current transformer
Nominal voltage 10-690 V 120 V The nominal secondary line-to-neutral
(in 4LN3, 3LN3 and 3BLN3 wiring
modes) or line-to-line (in 4LL3, 3LL3,
3BLL3, 3OP2, 3OP3 and 3DIR modes)
voltage. Used as a reference voltage
for the EN50160 evaluation.
Maximum demand
load current 0-20,000 A 0 The maximum demand load current
(0 = CT primary)
Nominal frequency 50,60 Hz 60 Hz The nominal line frequency
Demand Setup
Power block
demand period 1, 2, 3, 5, 10, 15,
20, 30, 60 min,
E=external sync 30 min The length of the demand period for
power demand calculations. If the
external synchronization is selected, a
pulse front on the digital input DI1
denotes the start of the demand
interval.
Number of blocks in
sliding demand 1-15 1 The number of blocks to be averaged
for sliding window demands
Volt/Ampere/THD
demand period 0-1800 sec 900 sec The length of the demand period for
ampere, volt and THD demand
calculations
