HERNANDEZ AREU, Orestes Nicolás; RAMOS GUARDARRAMA, Josnier  y  PERERA ESCOBAR, Regla. Measurement of inrush current in distribution transformers. Energética [online]. 2017, vol.38, n.2, pp.132-142. ISSN 1815-5901.

The inrush current phenomenon is probably the most common transient process associated with the operation of transformers, due to the regular connection and disconnection manoeuvres. High values of inrush current can cause a series of adverse effects for both the electrical system that feeds to the transformer and the transformer itself, including momentary voltage drops, temporary harmonics surges, electromechanical stress in the windings, insulation deterioration, etc. The "inrush current - time" characteristic of the transformers is an usually requested information by the clients, that’s why it must be known and provided by manufacturers. In this project is proposed the use of a laboratory setup that is relatively simple and inexpensive to carry out this measurement, such as the use of software for managing and analyzing the results

Palabras clave : inrush current phenomenon; inrush current; measurement of inrush current.
