In this video Barry Bolling, application engineer at Yokogawa Test & Measurement, explains why the two-wattmeter method works, offers a simple algebraic proof of two watt-meter method, and performs an example power measurement on a BLDC motor drive using the Yokogawa WT3000 power analyzer. Barry also discusses when the two-wattmeter method is okay to use as well as when you may wish to graduate to the three-wattmeter method.
