/1 Standby Power & IEC62301

/1 Standby Power Legislative drive to reduce standby power consumption Increased consumer awareness of cost to pocket and the environment With the political and market forces of climate change and rising energy costs their has been an International Agreement to reduce the energy consumption of electrical equipment in the “ standby mode “, this is known as the IEA “1-watt Plan “ The agreed measurement standard and accuracy is IEC 62301

/1 Who Does This Affect ? All manufacturers of domestic products Every country can apply its own limits by directive or legislation. In Europe the generally accepted directive is the “ Energy Star” but Germany also has “Blue Angel” and Scandinavian countries have adopted the “Nordic Swan” The measurement standard for all the world wide directives is IEC62301

/1 Measurement Overview

/1 Check Test Environment The Voltage source must be verified through the test to comply with : Total Harmonic Content (THC) of the supply voltage must be less than 2% The THC is up to and including the 13 th harmonic Voltage Crest Factor shall be between 1.34 and 1.49 during the measurement

/1 Power Measurement Accuracy The measurement standard requires a Watts measurement resolution of: 0.01WLoad 10W or less* 0.1WLoad W 1WLoad greater than 100W * Requires an instrument with a minimum current range of 10mA

/1 Measurement Requirements The product should first be allowed to stabilize for a minimum of 5 minutes Then run a measurement test for 5 minutes Recording every second Vrms, Vcf, Vthd, V Harmonics ( up to 13 th ) Arms, Acf, Wrms Freq

/1 Measurement Requirements Standby power is very small, with short bursts of power. The PM1000+ has a 1MHz bandwidth and high sample rate to capture these distorted waveforms

/1 The Measurement System Key Points Universal Plug Socket for UUT External 1 ohm Shunt for low power 10W< resolution Direct shunt connections for measurement of asymmetric waveforms which include a DC component (H0)

/1 Power Stability Less than 5% deviation from the maximum value observed Measurements are stable and the Watts reading can be directly reported

/1 Stable Power ? No If the power measure varies by more the 5% then either of the following options may be chosen Average Power – calculate the average of all the power readings over the test period Accumulated Energy- measure the Whrs consumed by the load. To calculate the Average Power, divide the energy consumed in Whrs, by the measurement period.
