22. An overcurrent relay is used to protect a circuit with a maximum 3-phase fault current of 8000 A primary A 400:5 current transformer ratio and a 5-A relay tap setting are selected. If the total secondary burden on the current transformer for the maximum fault condition is 1:10n, the excitation voltage (V) that must be developed by the current transformer is most nearly a240-V form 2 S electric meter is connected to the following loads: 240-V Load _(AB)=480W at unity power factor 120-V Load _(A)=240W at unity power factor 120-V Load _(B)=360W at unity power factor The neutral current (ampere) in the meter is most nearly: A. 1 B. 4 C. 5 D. 9
