If the load is 100 A ,the meter records correctly if the CT ratio is 100/5 as the meter gets 5A current . If the CT ratio is 600/5 the current in the meter will be 5/6 A for the same load current . Hence to get the correct reading ,multiply by 6.

In secondary transmission i.e., in distribution side, supply for homes are connected through different phases in order to balance the 3 phase load. But in practical we saw nearby house doesn't have power due to single phasing. But other two phases give supply. How it's possible? it doesn't make "single phasing"?
