    CT ISOLATION CHAPTER 10: MISCELLANEOUS 10.2 CT Isolation 10.2.1 MM3 Motor When is withstand important? Manager 3 CT Withstand is important when the phase or ground CT has the capability of driving a large Withstand amount of current into the interposing CTs in the relay. This typically occurs on retrofit installations when the CTs are not sized to the burden of the relay.
  • Page 211 CHAPTER 10: MISCELLANEOUS CT ISOLATION The curve below represents a typical excitation curve for a CT. The Y-axis represents secondary exciting voltage; the X-axis represents the secondary exciting current. When the CT secondary exciting voltage level is picked off the graph, the corresponding secondary exciting current is the amount of current required to excite the core of the CT.
