Introduction
NOTES
¬
For all applications/outputs, the voltage parameters can represent line-to-neutral or line-to-line voltages depending on the
wiring configuration selected in the Powermeter. (4Ln3/3Ln3 = line-to-neutral voltages; all other configurations = line-to-line
voltages).
-
In 3-wire connection schemes, the individual phase values for power factor, active power, apparent power and reactive power
will be zero, because they have no meaning. Only total three-phase power values can be used.
®
In all grounded connections using either 4Ln3 or 4LL3 wiring configuration s, harmonic voltages will represent line-to-neutral
voltages. In a 3-wire direct connection, harmonic voltages will represent line-to-neutral voltages that arise on the Powermeter's
input transformers. In a 3-wire open delta connection, harmonic voltages will comprise L12 and L23 line-to-line voltages.
¯
Display readings are the maximum demands over entire time of survey.
°
Measurements can be made via 16 programmable Min/Max registers.
