Advanced Demand & Energy Meter Tab
Advanced
energy meter list
Advanced energy metering tab meters multiple total apparent power and power factor
parameters, calculated using arithmetic and vector sums of the individual phases. These
methods may produce different values with distorted and/or unbalance phases.
Demand/Advanced Energy include various energy parameters on per phase and total
basis as well as in forward and reverse mode. Some parameters such as displacement
power factor are only valid for the fundamental frequency. The Advanced energy tab
also allows trending of rapid voltage changes that result in light flicker. Flicker
parameters under the Advanced energy tab are used primarily for specialized testing.
Flicker measurements are calculated as per IEC 61000-4-15.
