Application
It takes the effective values of UMG 511 current and voltage with each 4 current and 4 voltage inputs from the 40-70 Hz networks. It calculates the electrical quantities of digital sign processor (DSP) with sling and analog-to-digital converter. In three-phase measurements, its load voltage can be identified as phase-neutral and phase-phase voltage. Load voltages are processed for harmonic analysis, flicker and event registration. For measuring the current events, a nominal current can be set additionally. 4. Current and voltage inputs meet a different measuring system. In general, these inputs are used for determination of current measurement in the neutral and earth line and possible potential between the neutral and earth line.
