ASPECTS REGARDING THE OPERATING REGIME IN CHARGE OF SINGLE PHASE ELECTRICAL TRANSFORMERS

Abstract

The paper presents a case study on the operating regime in charge of single-phase transformers. The case study relates to a functional model that has in its configuration a single-phase electric transformer with an apparent power of 250 VA and a transformation ratio of 230 / 27V. The monitoring of the electrical parameters in the load operation of the single-phase electric transformer was done by means of an electronic measuring block fed from an independent voltage source.
