Differences between measuring transducers

Ou r measu ring t ra nsducers ca n be d ivided i nto two g roups: MI40 0 mu ltifunc tiona l measu ring t ra nsducer a nd allthe others.MI40 0 is t he most power ful mu ltifunct iona l meas uring tra nsducer. It super vises simu lta neously a ny 3 va lues of a ne lectrica l s ystem. It has the capa bil ity of measu ring more t ha n 50 d iffe re nt e lectr ical q ua nt ities such as: TRMSva lues of voltage, c urrent, kW, kvar, kVA, PF, Hz, MD, THD etc i n one inst rument.
