am gasit urmatoarea definitie si nu stiu ce sa inteleg din ea:

Asimetrie(%) = Deviatia maxima fata de medie a valorilor de tensiune / Media tensiunilor

 

Eu de aici inteleg urmatoarea chestie :

- intre 2 faze nu am cat ar trebui sa am in mod normal 380 si am mai putin sau mai mult

de exemplu dak am 370 v intre R si S , 380 intre S si T si 380 intre S atunci asimetria ar fi ceva de genu

 

 

A = [(370+380+380)/3 - 370] / [(370+380+380)/3] *100?

am inteles bine sau nu?
