WebA power analyzer is an instrument that measures and quantifies the rate of power flow in electrical systems. Power flow is expressed in Joules/second (J/s) or kilowatt-per-hour (kW/h). Electrical power is the rate per unit of time that electrical energy is transferred in an electrical system between two points.
