Prisotnost višjeharmonskih tokov v poslovni stavbiJezernik, Karel ; Harnik, JožeSodobne pisarniške naprave povzročajo višjeharmonske tokove in s tem vplivajo na večji račun za porabljeno energijo. Posebno zaznavno povečanje izgub je v poslovnih stavbah, kjer se uporabljajo ... osebni računalniki, tiskalniki, faksi in frekvenčni pretvorniki večjih moči. V sestavku je opravljena analiza izvorov višjeharmonskih tokov, ki jih povzročajo sodobni elektronski porabniki. Narejen je izračun izgub moči za inštalacijo sodobne poslovne zgradbe. Analiza prikazuje, da so izgube v vodnikih in transformatorju, ki jih povzročajo nelinearni elektronski porabniki, do 1,9-krat večje kot pri sinusnih obremenitvah (linearni porabniki). Za stavbo z velikim številom nelinearnih porabnikov je predstavljena tudi izmerjena omrežna napetost, ki pa nikakor ni več sinusne oblike. Tem izgubam se je mogoče izogniti z vgradnjo aktivnih ali pasivnih vezij za odpravljanje višjeharmonskih tokov. Centralna kompenzacija jalove energije v takih primerih napajanj ni več zadovoljiva. V smislu zmanjšanja vsebnosti višjeharmonskih tokov so predlagani novi predpisi in priporočila IEC o elektromagnetni kompatibilnosti električnihSource: Elektrotehniški vestnik. - ISSN 0013-5852 (Letn. 64, št. 4, 1997, str. 181-188)Type of material - article, component partPublish date - 1997Language - slovenianCOBISS.SI-ID - 3164182
