The general circuit diagram of single phase electrodynamometer power factor meter is given below. The factor 3 can only be used to convert between systems or scale the measurements of only one wattmeter on balanced linear systems.
An Introduction To Capacitor Based Power Factor Correction
3 phase power factor meter connection diagram. Thanks for reading about power factor meter working principle. The power factor meter determines the types of load using on the line and it also calculates the losses occur on it. The power factor meter measures the power factor of a transmission systemthe power factor is the cosine of the angle between the voltage and current. Psif we can get to 200 likes i will make another. The power factor of an unbalanced poly phase circuit is not uniquely defined. Power factor meter definition.
Below is the connection of 3 phase three phase or poly phase 3 phase4 wire kwh meter digital or analog energy meter from the supply to the main distribution board. Now the pressure coil is split into two parts one is purely inductive another is purely resistive as shown in the diagram by resistor and inductor. Power factor correction capacitors are used for this purpose. Power factor meter connection is shown in figure. When a motor is operating at full load the activereactive power ratio is high and thus the power factor of the motor is high. The power factor of a balanced polyphase circuit is the same as that of any phase.
Todays 3 phase smart meters can connect to a wide area network wan and the cloud through a data concentrator and a home area network together with in home devices in addition to gas. The field of. Power factor meter connection diagram. The deflections in three phase power factor meters are independent of frequency and waveform since the currents in the two moving coils are affected in the same way by any change of frequency. A direct reading power factor meter can be made with a moving coil meter of the electrodynamic type carrying two perpendicular coils on the moving part of the instrument. Three phase electricity meters are designed essentially to measure energy consumption and its quality factor as well as provide means to prevent tampering.
A power analyzer with vector mathematics capability will also convert phase to neutral or wye quantities to phase to phase or delta quantities. In this video you will see how to wire power factor relay and power capacitors to create a complete power factor correction panel.
