Abstract
PURPOSE: To obtain a digital power measuring unit with which highly accurate and reliable power measurements and measured data transmissions can be performed by sampling the voltage and surren tof a system at a definite cycle, by multiplying the voltage and current information to compute the product, then, by adding the present product and the product of the sampling performed prior to the present by a definite time length to output the digitl values of the effective power and the reactive power of the system.
