Neutral conductor current
The cumulative value of the energy counters in 3-phase operation is obtained from the
sums of the individual values of the phases.
Inflow and outflow energy meters are always positive values.
The operating hours counter for the entire module is calculated from the sum of the
operating hours of the individual phases.
Neutral conductor current
If you operate the AI Energy Meter 480VAC ST with connection type 3P4W, the neutral
conductor current is also determined 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 neutral is subject to a "Low limit for measuring current" like all other current
measurements. The lowest value of all three configured low limits is used as the minimum
value.
If one of the conditions is not met, 0 is entered as the value for the neutral conductor current.
You can read the determined neutral conductor current using measured value data record
142.
