what happend if the protection ct is by mistake put instead
of measuring ct & vice versa?
Answer Posted / kajanijam
If we use protection CT for metering purpose,its core has high saturation point.if any fault occurs, the core is not saturated.so it will damage the meters connected to CT secondary
and if we use metering CT for protection purpose,its core has low saturation point,so CT core saturated low value of current,so relay will be inoperative
