DTU line loss acquisition module (WE6631-C)

 

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