225. DEFINITION OF PARAMETERSParameter Symbol Unit DefinitionNominal primary AC current IPN AC Arms Rated AC current for continuous operationNominal primary DC current IPN DC A Rated DC current for continuous operationMeasuring range ÎPM A Max DC current (or peak value) that can be accurately measuredOverload capacity ÎOL A Max primary current without damage. Device will be saturated du-ring the overload period.Nominal secondary current ISN mA Value of the device’s output signal when a current of nominal valueflows in a conductor placed inside the device’s center holePrimary / secondary ratio n1:n2 none e.g. 1:1500 means if primary current is 600A, then secondary cur-rent (device’s output signal) is 600A / 1500 = 0.4A or 400mAMeasuring resistance RM Ω The device’s output current must be ”closed” to enable the fluxcompensation.Linearity error ƐL ppmμAMaximum deviation or error (in ppm or in absolute μA value) be-tween the output signal of the current transducer at any given pointbetween 0 and ±ÎPM and the linear regression line obtained from aseries of actual output values from -ÎPM to +ÎPM measured at regularcurrent value intervals between these two extremes.Offset current(including earth field) IOE ppmμAValue of the device’s output signal when there is no primary currentin the device’s center hole |
