http://learnmetering.com/pages/ct-and-pt-calculations/ WebThe excitation curve shown in Figure 4 represents a C400, 2000:5 multi-ratio bushing ct and is a measure of ct performance that can be used to determine ratio correction factors at various levels of steady-state excitation. Where it has a well-defined knee-point, it has no discernable point of saturation.
WebThe class designation is an approximate measure of the CT's accuracy. The ratio (primary to secondary current) error of a Class 1 CT is 1% at rated current; the ratio error of a Class 0.5 CT is 0.5% or less. Errors in phase … WebThis is why calibration of the CT is generally for a specific type of ammeter. Most current transformers have a the standard secondary rating of 5 amps with the primary and secondary currents being expressed as a ratio such as 100/5.
