WebSep 1, 2005 · Siemens offers three ways to stop motors in its Sirius starters: coast to rest, soft stop, and dc injection. New Sirius 3RW44 combines dc injection braking and closed-loop torque control (where voltage is gradually reduced using software and current feedback) to enable rapid stoppage of driving loads. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime. For measuring these DC components, we need a Power Quality Analyzer which can handle DC voltages and DC currents. See more The low network impedance of an AC network means that a small DC voltage from the grid connected inverters creates a large DC current injection. This DC current is not a fault … See more Modern variable speed drives, especially those with active rectifiers, also inject DC into AC grids. Other non-linear and non-symmetrical loads like LED lights can inject DC, too. The … See more A report by the UK’s BSRIA (Building Services Research and Information Association) monitored DC levels in buildings. The … See more The DC component will not be recognized by the kWh usage meters. Current and voltage transformers will not pass the DC component to the secondary, so the meter does not see it.
