Harmonics or disturbances in the range above 2 kHz are becoming noticeable in networks due to the introduction of inverter based distributed generators, and are […]

Dealing with inrush currents in distribution transformers

Among the subtleties associated with distribution switchgear configuration, inrush current is a necessary evil which must be taken into consideration. It is the source of much frustration for field operators and SCADA control teams; when issuing a close command on an open breaker results in an immediate trip. Was it genuine fault? Is it risky […]
