Magnetization inductance lm pu
WebThe single-phase two-winding transformer models two coupled windings on the same core. The magnetization inductance Lm can be linear or with saturation, it is modeled on the primary side of the transformer. Core losses are modeled as Rm resistance located on the primary side of the transformer. WebJul 1, 2024 · by Equation 5. By utilizing this observation, the magnetizing inductance that is responsible of i m can be measured as outlined in the following section. Magnetizing (Primary) Inductance Measurement 1. To measure the magnetization inductance, the secondary windings are left open so that the current running through it becomes zero. 2.
