The invention relates to a method performed by a control unit (301) for determining an indication of whether three phase cables (101) are correctly or erroneously connected between power electronics (103) and an electrical machine (105) comprised in an at least partly electrically operated vehicle or vessel (200). The control unit (301) triggers generation of a current vector in the electrical machine (105) from a voltage vector. The voltage vector has a voltage angle. When the current vector has a reached a current amplitude reference, the control unit (301) obtains a current angle of the current vector and signs of derivatives of the voltage angle and the current angle. Based on the signs of derivatives, the control unit (301) determines an indication of whether or not the phase cables (101) are correctly or erroneously connected.
A METHOD FOR DETERMINING AN INDICATION OF WHETHER THREE PHASE CABLES ARE CORRECTLY OR ERRONEOUSLY CONNECTED BETWEEN POWER ELECTRONICS AND AN ELECTRICAL MACHINE COMPRISED IN AN AT LEAST PARTLY ELECTRICALLY OPERATED VEHICLE OR VESSEL
VERFAHREN ZUR BESTIMMUNG EINER ANZEIGE DARÜBER, OB DREI PHASENKABEL ZWISCHEN LEISTUNGSELEKTRONIK UND EINER ELEKTRISCHEN MASCHINE, DIE IN EINEM ZUMINDEST TEILWEISE ELEKTRISCH BETRIEBENEN FAHRZEUG ODER SCHIFF ENTHALTEN IST, KORREKT ODER FEHLERHAFT ANGESCHLOSSEN SIND
PROCÉDÉ PERMETTANT DE DÉTERMINER SI DES CÂBLES TRIPHASÉS SONT BRANCHÉS CORRECTEMENT OU PAR ERREUR ENTRE L'ÉLECTRONIQUE DE PUISSANCE ET UNE MACHINE ÉLECTRIQUE COMPRISE DANS UN VÉHICULE OU UN BATEAU AU MOINS PARTIELLEMENT À COMMANDE ÉLECTRIQUE
