Primary current
WebThe primary of CT has few turns and it has very less resistance. The primary winding resistance and reactance is denoted by R p and X p respectively. The secondary winding resistance and reactance is denoted by R s and X s respectively. The magnetization components of the current transformer are Rc and X m.R c is responsible for the core loss … WebJul 8, 2024 · The current Rating of the primary winding of a current transformer is determined by the maximum value of the load current to be measured. For example, if the current Rating is 400 A with a secondary rating of 5A, the ratio between the primary and secondary is 400:5, or 80:1.
