what are the difference between protection class CT and
Class PS CT

Answer Posted / mauhammad yasir abdul-rub

The Difference Between protection class and metering class
is mainly of saturation, the saturation values of protection
class is higher as when fault occur protection CT must not
get saturated as high current flows and metering CT can be
saturated as when fault occur metering is not necessary,
accuracy is also a factor but not the main factor
