Network 1 = single phase
Network 2 = 3-phase balanced
Network 3 = 3-phase unbalanced without neutral & without leak current ( IR+IS+IT=0 )
Network 4 = 3-phase unbalanced with neutral
Network 5 = 3-phase unbalanced without neutral, measurement of the 3 currents IR, IS, IT & In leak.
The impedance and the harmonics are calculated on the R phase.
The harmonic distortion rate is calculated like below :
Y2²+Y3²+...+Y30²
THD = 100 x
Yn is the harmonic range of the rank n
Y1
= H2²+H3²+...+H30² Hn is the % rate of the n harmonic (Hn display value)
The measured parameters are programmed on the indicators like below : (details page 21)
