Modern electrical networks require detailed information not only on the quantity of electrical power being supplied to consumers but also on the quality of that power.

Such parameters as the individual phase voltages and currents have long been monitored. However, modern demands have made it necessary to record such aspects as the reactive and real power flows, system harmonics and various sequence components.
