Suppose the CT ratio is 2000/1 and the CT gets saturated if there is flow of 10 kA current through its primary, then Instrument Safety Factor is given as. Instrument Safety Factor, ISF = CT saturating Current / Rated current. = 2000×5 / …

Instrument security factor (factor of security): This typically takes a value of less than 5 or less than 10 though it could be much higher if the ratio is very low. ISF or instrument security factorof current transformer is defined as the ratio of instrument limit primary current to the rated primary current. The instrument limit primary current of metering CT is the value primary current beyond which CT core becomes saturated. Se mer Following are some of the normally used terms associated with instrument transformer, that is, both for current transformer and voltage transformer. Se mer There is always some difference in expected value and actual value of output of an instrument transformer current error and phase angle error count in CT, as because primary … Se mer Knee point voltage of current transformeris significance of saturation level of a current transformer core mainly used for protection purposes.
