1. ALF - Accuracy Limit Factor
It is the ratio of Instrument limit primary current to the Rated primary current.
2. KPV- Knee point Voltage
It is defined as a point where 10% increase in the Secondary Voltage causes an increase in the Secondary Current by 50%.
3. Iexc- Excitation current
A transformer exciting current is the current or amperes required to energize the core.
4. Rct @75°C - Resistance of Secondary winding on CT at 75°C.
