connected.
The output level is about
one fifth or five times the
expected value, although
the input signal is healthy,
and the correct primary
scaling has been applied.
The current
input
configuration
secondary may
be set
incorrectly.
Check the selection for
Current Secondary
.
Current and derived power values will be reported low if a
CT with 1 A secondary is connected to inputs set for 5 A.
They will be reported high if the condition is reversed.
The output level from the
transducer is lower or
higher than expected,
although the input signal is
healthy and the correct
primary and secondary
scaling has been applied.
The phase
inputs may be
connected
incorrectly.
The wiring
configuration
may be
incorrectly
selected.
Check that the physical connections for each phase and
ensure that phase 1 is connected to L1 inputs, phase 2 to
L2 inputs, and phase 3 to L3 inputs.
Check the selection for
Measurement method
,
wiring
and
connection diagram
.
There is some doubt
related to accuracy of input
and output measurements
The transducer
is not measuring
as per
configured input
and output
range
Measure the input and output of the transducer using a
suitable measurement device. The device being used must
support the measurement ranges configured in the
transducer. By comparing the result with configured input
and output ranges, any deviation can be easily detected
