Neutral current
If you operate the AI Energy Meter HF with connection type 3P4W, 3P4W1 or 3P3W, the
neutral current is also calculated under the following conditions:
● Transmission factors of all phase currents (primary and secondary currents) are identical.
● Measured phase currents are greater than the value of the "Low limit for measuring
current parameter.
● The parameter "Reverse current direction" must be the same on all phases.
If one of the conditions is not met, 0 is entered as the value for the neutral current. You can
read the neutral current calculated using measured value data record 142.
Procedure
Data record 142 is located on the AI Energy Meter HF. Use the RDREC instruction to read
out the data record from the module. This system function block is stored in the STEP 7
library.
