We are measuring AC current to combination load/generators and want to read directionally up to 100Amps, which CT would be appropriate?

Dear Sir,

An AC current on its own has no direction or polarity. AC values can only have polarity when referenced to another AC value. To determine whether a generator/load is supplying or using energy, the designer must use either a power transducer (CR6200 Series) or a power factor transducer (CR6300 Series). For your convenience I have attached the catalog page of each product line.
