5–10 PQMII POWER QUALITY METER – INSTRUCTION MANUALCHAPTER 5: SETPOINTS5.2.7 Calculation ParametersPATH: SETPOINTS Ö S1 PQMII SETUP ÖØ CALCULATION PARAMETERSThe PQMII can be programmed to calculate metering quantities and demand by variousmethods.• EXTRACT FUNDAMENTAL: The PQMII can be programmed to calculate all meteringquantities using true RMS values or the fundamental component of the sampled data.When this setpoint is set to “Disable”, the PQMII will include all harmonic content, up tothe 32nd harmonic, when making metering calculations. When this setpoint is set to“Enable”, the PQMII will extract the fundamental contribution of the sampled data onlyand use this contribution to calculate all metering quantities. Many utilities base theirmetering upon fundamental, or displacement, values. Using the fundamentalcontribution allows one to compare the quantities measured by the PQMII with thelocal utility meter.• CURRENT DEMAND TYPE: Three current demand calculation methods are available:thermal exponential, block interval, and rolling interval (see the Demand CalculationMethods table below). The current demand for each phase and neutral is calculatedindividually.• CURRENT DEMAND TIME INTERVAL: Enter the time period over which the currentdemand calculation is to be performed.
