Measuring power quality in electrical installations

Background

A perfect electrical supply would deliver a constant frequency sinusoidal voltage waveform with unvarying magnitude. In daily work, power supplies deviate from this ideal situation because system loads vary and phenomena such as transients and outages may occur. If the power quality of the network is good, loads connected to it will run satisfactorily and efficiently. Insufficient power quality, however, can lead to failures of machinery, electric control systems or computers connected to the electrical supply network.

Power quality measurements characterize the degree to which a practical supply resembles the ideal situation, in terms of harmonic pollution, reactive power and load imbalance.

This entails measurements on the supply including frequency, interruptions, flickering, harmonic and interharmonic voltage, voltage variations like dips, temporary overvoltage or rapid changes and voltage unbalance. The EN standard defines the supply voltage characteristics of the electricity by public distribution systems for these measurements. The standard also includes compliance limits (see table).
