Dual-channel sampling systems
Abstract
The application of dual channel sampling techniques to the measurement of electrical power is described, and, to a lesser extent, so is the application of electrical phase angle measurements. Theoretical relationships are developed for describing these sampling measurements and their associated errors. The procedures that can be used to calibrate such dual channel instruments for these applications are also described. A diagram of the basic dual channel sampling system to be analyzed is given.
