How to make 3phase 3 wire "delta" power measurements
How to make 3phase 3 wire "delta" power measurements
In this video we explain how three-wattmeter method works, offer a simple algebraic proof of three watt-meter method, and perform an example power analysis on a BLDC motor drive using the Yokogawa PX8000 Power Scope. We also discuss when the two-wattmeter method is okay to use as well as when you may wish to graduate to the three-wattmeter method.
