A potential transformer must be used for voltage over 600V. A current transformer must be used for currents over 10 Amps.
Calibration is the means to provide a ratio of primary to secondary power.
The calibration of meters and transducers is slightly different, in that, a meter has a definite scale in power which dictates the calibration based on scale, CT and PT ratios. A transducer ,when used to power a meter, must also be calibrated as if it were a meter since the meter scale sets calibration When a tranducer is used to provide signal to a DCS or other data gathering system, a different set of rules apply. Since most switchgear manufactures don't know what the transducer output will be used for, then standard calibratioin rules apply. Industry standard is 1500 watts for 4 wire and 1000 watts for 3 wire. Use the example that you have 10 feeders on a motor control center.
