The accuracy limit is defined by the peak instantaneous error during the specified transient duty cycle. K-class . This principle states that an alternating magnetic flux in the presence of a loop of wire induces a voltage across that loop. First the fundamental theory of directional earth-fault protection is recalled. If the burden of a current transformer for metering is much higher than the load, instruments and devices could be damaged if short circuit occurs somewhere. C- or K-classification applies to all tap sections of the current transformer winding, but the accuracy class (i.e, C400, C800, etc.) This example indicates a current transformer with an accuracy of ±1.2%, and a maximum allowable secondary burden of 0.2 Ω (or 5 VA on a 5 A secondary CT). The value of the apparent power (in volt-amperes at a specified power (factor) which the current transformer is intended to supply to the secondary circuit at the rated secondary current and with rated burden connected to it. .
