POWER FACTOR METER DESCRIPTION

Microprocessor Based, 96 x 96 mm sq, For 3 Phase 4 Wire 3 Element, Red LED Display. A power factor meter is an electric instrument which is used to measure the power factor of various electrical machines like DC Generator, AC Motor, Transformer etc and for measuring the power factor of various transmission and distribution lines of various electric power supplies. These power supplies may be from Grid Stations, Substations or from Power Houses. Power factor must be 0.8 to unity if Power Factor Decreases from 0.8 then the voltage and the current will imbalanced and the power is disturbed. So, in grid stations, Substations the power factor must be between 0.8 to unity (1) leading. The Power Factor is the cosine of angle φ between the voltage and the current of the transmission lines and electrical machines.
