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

3106-046/1

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

5106-046/1

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 13th harmonic

Voltage Crest Factor shall be between 1.34 and 1.49 during the measurement

Power Measurement Accuracy

Power Measurement Accuracy

The measurement standard requires a Watts measurement resolution of:

0.01W Load 10W or less*

0.1W Load 10-100 W

1W Load greater than 100W

* Requires an instrument with a minimum current range of 10mA

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 13th )

Arms, Acf,

Wrms

Freq

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

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)

Power Stability

Less than 5% deviation from the maximum value observed

Measurements are stable and the Watts reading can be directly reported

11106-046/1

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.
