#135483 - Calculate Rms voltage Responding to: ???'s previous message |
Ok.Here is the values i get form A/D convesion .The Vp-p values
For 245 V rms i get 467 Vp-p (A/D value) For 230 V rms i get 441 Vp-p (A/D value) For 200 V rms i get 390 Vp-p (A/D value) For 170 V rms i get 339 Vp-p (A/D value) With this A/D values i can't match the math type for rms A for the peaks i a get the peak values for sure cause i am sampling the sine wave for enough time. |
