A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...
An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...
When designing ground-fault protection (GFP) for a power distribution system, you should always consider the nature of the power source. If the power source is from a separately derived system, you ...
