core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing these simple tests the values for the equivalent circuit of a transformer (see Figures 1 &2)

1ϕ and 3ϕ Transformer for Open-Circuit and Short-Circuit testAbstract Transformer is a static devices that changes Ac electric power at one voltage level into AC electric power at another voltage level through the action of a magnetic field. It consists of two or more coils of wire wrapped around a common ferromagnetic core. These coils are not directly connected usually. The only connection between the coils is the common magnetic flux present within the core. One of the transformer windings is
