 Italian term or phrase: terna asimmetrica/simmetrica di tensioni Labels for two graphs in a manual relating to UPS systems. You can the links to view the graphs: Terna asimmetrica di tensioni http://www.keytranslations.co.uk/images/asimmetrica.JPG Terna simmetrica di tensioni http://www.keytranslations.co.uk/images/simmetrica.JPG The answer 'circuit' was provided in this previous question: http://www.proz.com/kudoz/italian_to_english/energy_power_ge... But I don't think that is correct here, as I think that 'terna' refers directly to the 'three phases' in a three-phase supply. Could it be "three-phase asymmetrical/symmetrical voltage"? I also found another resource on this topic: http://www.elettricoplus.it/temi/Normativa_Elettrica/articol... ...Se i tre carichi sono uguali, le tre correnti formeranno una terna simmetrica come quella delle tensioni... La figura 4 riporta l'andamento nel tempo della terna di tensioni. In generale un sistema trifase è detto: • simmetrico, se le tensioni delle tre fasi hanno uguale ampiezza e sono equisfasate di 120° l'una dall'altra; • equilibrato (o simmetrico nelle correnti), se le medesime proprietà di simmetria di cui sopra valgono per le tre correnti di fase. Any other ideas welcome. Thanks in advance for your help.

 Thanks to all for your contributions, I think this answer must be on the right lines. I've seen 'triad' used but only in translated texts.4 KudoZ points were awarded for this answer

agree  James (Jim) Davis: "three phase symmetrical/asymetrical voltage" as labels for those graphs. I once wired up a three-phase circuit a long time ago.
