Abstract
U ovom radu analiziran je povratni utjecaj vezan uz struju sekundara transformatora uzrokovanu radno-induktivnim trošilom i ispravljačem u punovalnom mosnom spoju. Mjerenja su provedena na multimedijalno-didaktičkoj opremi Lucas-Nulle. Za grupe spojeva transformatora Yy0, Yd0, Yy10 i Yy6 odrađena su mjerenja te prikazani bitni valni oblici. Provedena je harmonijska analiza spektralnim analizatorom koji se nalazi unutar programskog programa Lucas-Nulle. Za spoj Yd0 provedeno je snimanje valnog oblika fazne struje vanjskim osciloskopom i strujnim kliještima. Dobivene vrijednosti THDI-a uspoređene su međusobno za različite grupe spojeva namota transformatora.
Abstract (english)
In this paper, the feedback influence related to the secondary current of a transformer caused by an operating-inductive consumer and a rectifier in a full-wave bridge connection is analyzed. Measurements were performed on Lucas-Nulle multimedia-didactic equipment. For the groups of transformer connections Yy0, Yd0, Yy10 and Yy6, measurements were performed and important waveforms were presented. Harmonic analysis was performed with a spectrum analyzer located within the Lucas-Nulle program. For the Yd0 junction, a phase current waveform was recorded with an external oscilloscope and current clamps. The obtained THDI values were compared with each other for different groups of transformer winding connections.
