Measuring Standby Power

Measurement of the power and energy consumed by common domestic and office appliances when they are in standby mode provides several challenges. Not only are the current and power levels very low (in the region 10 milliwatt to 1 watt) but standby power is often drawn in irregular bursts from the AC line.
