4 3. Calculation of the composite error/ MPE During the type approval examination the influence factors for temperature, frequency and voltage are determined per load point. The table below presents the sum of the square values per load, determined via the following formula:- e (T, U, f) = ( e 2 (T, I,cos ), e 2 (U, I,cos ), e 2 ( f, I,cos )) where e(t, I,cos ) = e(u, I,cos ) = e( f, I,cos ) = Additional error due to variation of the temperature at the same load Additional error due to variation of the voltage at the same load Additional error due to variation of the frequency at the same load Current PF Cos e(uicos) e(ficos) %MPE %MPE %MPE %MPE %MPE %MPE Imin Itr Itr Imax Itr 0.5ind Itr 0.5ind Imax 0.5ind Itr 0.8cap Itr 0.8cap Imax 0.8cap Page 4 of 5
