PowerLogic™ PM5100 series user guide Chapter 8—Measurements and calculations Chapter 8—Measurements and calculations This section describes how the meter processes measured and calculated data. Real-time readings The power and energy meter measures currents and voltages, and reports in real time the RMS (Root Mean Squared) values for all three phases and neutral. The voltage and current inputs are continuously monitored at a sampling rate of 64 points per cycle.
Chapter 8—Measurements and calculations PowerLogic™ PM5100 series user guide Power factor min/max convention The meter uses the following convention for power factor minimums and maximums: • For negative PF readings, the minimum PF value is the measurement closest to -0 for PF readings between -0 to -1. For positive PF readings, the minimum PF value is the measurement closest to +1 for PF readings between +1 to +0.
PowerLogic™ PM5100 series user guide Chapter 8—Measurements and calculations IEEE mode In IEEE mode, the PF sign is determined by the type of load (inductive or capacitive) contributing to the reactive power component of apparent power. PF sign is positive (+) for capacitive loads (leading power factor). PF sign is negative (-) for inductive loads (lagging power factor). Related topics • • To change the HMI mode, see “Setting up regional settings” on page 35.
Chapter 8—Measurements and calculations PowerLogic™ PM5100 series user guide The following illustration shows the different ways power demand is calculated using the block interval method. In this example, the interval is set to 15 minutes. Block interval demand example Demand value is the average for the last completed interval Calculation updates every 15 seconds 15-minute interval 15 30 45 60 . Time (sec) ..

When setting up this type of demand, you can choose Clock Sync Block (clock-synchronized block demand) or Clock Sync Roll Blk (clock-synchronized rolling block demand). Clock Sync Roll Blk requires that you specify a subinterval. Thermal demand Thermal demand calculates the demand based on a thermal response, which imitates the function of thermal demand meters.
Chapter 8—Measurements and calculations PowerLogic™ PM5100 series user guide Predicted demand example Beginning of interval Demand for last completed interval 15-minute interval Predicted demand if load is added during interval; predicted demand increases to reflect increased demand Partial Interval Demand Predicted demand if no load is added.
PowerLogic™ PM5100 series user guide Chapter 9—Power quality Chapter 9—Power quality This section describes the meter’s power quality features and how to access power quality data. The meter measures voltage and current harmonics up to the 15th harmonic, and calculates Total Harmonic Distortion (THD) and Total Demand Distortion (TDD and tdd). Harmonics overview Harmonics are integer multiples of the fundamental frequency of the power system.
Chapter 9—Power quality PowerLogic™ PM5100 series user guide THD and thd calculations The meter supports two methods of calculating total harmonic distortion: THD and thd. THD is a quick measure of the total distortion present in a waveform and is the ratio of harmonic content to the fundamental. The meter uses the following equation to calculate THD: HC THD = -------- 100 H1 Where H1 is equal to the fundamental harmonic. thd is an alternate method for calculating total harmonic distortion.
PowerLogic™ PM5100 series user guide Chapter 9—Power quality Example: 7th to 15th harmonics for line-to-neutral voltage Phase A Phase B Phase C The vertical axis of the harmonics graph indicates the harmonic’s magnitude as a percentage of the fundamental harmonic, and is scaled based on the largest harmonic displayed. At the top of each vertical bar is a marker that shows the maximum value of the harmonic.

PowerLogic™ PM5100 series user guide Chapter 10—Verifying accuracy Chapter 10—Verifying accuracy All meters are tested and verified at the factory in accordance with International Electrotechnical Commission (IEC) and American National Standards Institute (ANSI) standards. Your digital power meter does not require re-calibration. However, in some installations a final accuracy verification of the meters is required, especially if the meters will be used for revenue or billing applications.
Chapter 10—Verifying accuracy PowerLogic™ PM5100 series user guide temperature before calibration to help ensure that the meters will reach their optimal accuracy at operating temperature. Most high precision electronic equipment requires a warm up time before it reaches its specified performance levels. Energy meter standards allow the manufacturers to specify meter accuracy derating due to ambient temperature changes and self-heating.
PowerLogic™ PM5100 series user guide Chapter 10—Verifying accuracy Verifying accuracy test The following are guidelines for testing the meter; your meter shop may have specific testing methods. DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E in the USA or applicable local standards. • Turn off all power supplying this device before working on it.
Chapter 10—Verifying accuracy PowerLogic™ PM5100 series user guide 6. Depending on the method selected for counting the energy pulses, configure the meter’s alarm / energy LED or one of the digital outputs to perform energy pulsing. Set the meter’s energy pulse constant so it is in sync with the reference test equipment. 7. Perform accuracy verification on the test points. Run each test point for at least 30 seconds to allow the test bench equipment to read an adequate number of pulses.
PowerLogic™ PM5100 series user guide Chapter 10—Verifying accuracy Where: • • EM = energy measured by the meter under test ES = energy measured by the reference device or energy standard. NOTE: If accuracy verification reveals inaccuracies in your meter, they may be caused by typical sources of test errors. If there are no sources of test errors present, please contact your local Schneider Electric representative.

PowerLogic™ PM5100 series user guide Chapter 11—Meter resets Chapter 11—Meter resets Reset commands clear the meter’s onboard data logs and related registers. Meter resets are typically performed after you make changes to the meter’s basic setup parameters (such as power system, frequency, or PT/CT settings), to clear invalid or obsolete data in preparation for putting the meter into active service. The meter reset commands are grouped into two categories: Global Resets and Single Resets.
