Power Meter (Pre-Owned)

A power meter is used to measure the flow of power (w) in either alternating current (AC) or direct current (DC) systems. This refers to the rate of electrical transferal between a power source and a sink, hence the alternative expression of power as energy per second (J/s). Measuring power flow is a critical yet rudimentary process that can be carried out with consummate ease using a standard power meter. Innovative power meters offer more than just power measurements. Additional calculations and analytical methods performed with advanced power meters include: efficiency mapping; Fast Fourier Transform (FFT) and harmonic analysis; fundamental power and root mean square (RMS) values; polar diagrams and symmetrical components; space vectors and DQ-currents.
