Switching, multicycle control and phase control are included. Cycloconverters are excluded. Examples of application include, but are not limited to, industrial oven controls, static motor starters, static relays, etc. This standard is intended to be used in conjunction with IEC Pub 146 (1973) [2] .l Reference is made to the appropriate section of IEC Pub 146 (1973) [2] where required. 517 $aIEEE Std 428-1981: IEEE Standard Definitions and Requirements for Thyristor AC Power Controllers 606 $aThyristors 615 0$aThyristors. 676 $a621.3137 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279436703316 996 $aIEEE Std 428-1981$92575727 997 $aUNISA
