FTU line loss acquisition module (WE6631-E)

 

WE6631-E feeder terminal line loss module (FTU electromagnetic type) is an electromagnetic voltage and current transformer access line loss acquisition module combined with the first and second fusion scheme of national  network.  It  can  measure  three-phase  voltage,  current, frequency, power factor, active reactive power, active reactive power and other electrical parameters, combined with FTU to achieve the acquisition of distribution line loss.The module is built into the FTU, with the national network measurement center test report, active power accuracy 0.5 S, reactive power accuracy 2.0. The module has the advantages  of  small  size,  high  precision,  good  reliability  and convenient installation.
