Peak demand

The maximum values for the kWD, kVARD, kVAD power, and amps (or peak demand) is maintained in the meter’s non-volatile memory. The peak for each value is the highest average reading since the meter was last reset. The power meter also stores the date and time when the peak demand occurred. In addition to the peak demand, the power meter also stores the coinciding average 3-phase power factor. The average 3- phase power factor is defined as “demand kW/demand kVA” for the peak demand interval.
