Abstract :
The first part of the paper summarizes the principal types of apparatus employed for the improvement of power factor, and gives a description of the modern static condenser and also of types of power-factor-rectifying plant that have been developed during the past three years. The second part of the paper outlines various forms of power-factor tariff in force in Great Britain, and is divided into two main classes; first, those based on kVA demand, and second, those incorporating a power-factor bonus or penalty on the total supply bill. Systems of metering employed in conjunction with power-factor tariffs are briefly dealt with.
