#135478 - Calculate Rms voltage |
Hello i am sampling a 3 phase voltage system.I want to sample those 3 sine waves and get the rms voltage .The method i use is by taking the Upper peak of the signal and the lower peak of the signal (Vp-p voltage).After that how can i convert it to Rms voltage .THe math type Vrms=Vp-p/2sqrt(2) it doesn't fits to my ocassion probably e.g.
I sample one sine wave i get from the A/D a value how can i convert that so i get a value e.g of 230 Volts |
