Measuring Power regulated by Zero Crossing SCR
... A watt transducer measuring the power regulated by a zero crossing controller must 1) filter the normal 120hertz ripple and 2) also filter the step changes in power from 0 to full scale as regulated by the controller. That means the watt transducer must average the power over the entire period of 18 ...
