MIN / MAX Values for Voltage and Current
Vmax[i] = max (Vdem[i]), Vmin[i]= min (Vdem[i])
Umax[i] = max (Udem[i]), Umin[i] =min (Udem[i])
Amax[i] = max (Adem[i]), Amin[i]=min (Adem[i]) (Avg calculation on 1s)
Peak Values for Voltage and Current
Vpp[i]= max (V[i][n]), Vpm[i] =min (V[i][n]), n
Upp[i]= max (U[i][n]), Upm[i]=min (U[i][n]), n
App[i]= max (A[i][n]), Apm[i] =min (V[i][n]), n
