Energy has become a critical component of computer system design, particularly in the embedded space where the source of energy is often finite. While hardware design has the more significant effect on the system’s power consumption, well designed system and application software make an important contribution to controlling the energy consumed. In order to optimise software systems to reduce en...

The flicker and harmonics generated by electric arc furnaces present a problem that is well known to both the steel industry and electrical utilities. This paper presents a method to compensate for measurement errors introduced by current and voltage transformers and anti-aliasing filters in a power quality measurement system. Dynamic compensation may be performed in real time using digital fil...
