• Phasors are a graphical means of representing the amplitude and phase relationships of voltages and currents. • As stated in the Handbook of Electricity Metering, by common consent, counterclockwise phase rotation has been chosen for general use in phasor diagrams.

Apr 16, 2019 · When viewing a vector diagram, understanding reference point and direction is imperative to understanding what power measurement the vectors represent. Knowing this, it is easy at a glance, to determine the required quantity each phasor represents.

Tutorial about the Power Triangle that is used to graphically represent the three power elements within an AC circuit

A vector diagram is a display of all of the voltage and current vectors measured at any location and plotted on a diagram indicating the magnitude and direction

Real power, VA and VAR’s are related as vectors, shown in the diagram below. The apparent power is the square root of the sum of the squares of the reactive power and the real power. Figure 2. Relationship Between the Three Types of Power. The vector graph above illustrates the components of a power draw.

Graphical Representation of Real Power, Reactive Power, Apparent Power and Power Factor. Real power, VA and VAR’s are related as vectors, shown in the diagram below.

Complex power, denoted by S, is the vector sum of real power and reactive power. Apparent power, denoted by |S|, is the magnitude of complex power. It uses the unit volt-amperes (VA) rather than watts. Power factor, abbreviated PF, will be discussed shortly. The following diagram is referred to as the power triangle. Figure 3.

• Review basic power concepts as they relate to Power Factor (PF) • What is a vector diagram? • How do different loads affect PF? • How does low power factor lead to lost revenue? • Show the vector diagram for each meter form and service type • See how vector diagrams help identify meter site errors that can recover lost revenue
