“TRANSFORMER 0.3 kW”

Laboratory performance and short-circuit three-phase two winding transformer and the characteristics of various load conditions.

Objectives of the study:

After completing the course, the student can do the following:

Connecting a single-phase transformer, then the concepts of “voltage conversion”, “current conversion” and “no-load current” in the respective experimental circuits.

Collect and measure measurement circuits to determine short circuit and steady-state voltage.

A transformer connected to a common load is evaluated taking into account voltage fluctuations and their effect on resistance.

Exploring and explaining voltage when connected to inductive or volume load.
