We do a good deal of underground cable calculations in conduit for voltages between 12kV and 230kV. We use a program called CYMCAP made by CYME (now owned by Eaton). At riser poles and transitions, you often have to dive a good bit deeper to fit in the 90 degree turn of the conduit. This causes...
I have a question about a 27kV ground switch we are installing in a HV yard. My substation technicians are having an issue with a ground cable we are being made to use. This company's standard is to use copper clad cable, which makes the cable OD much bigger than it would be with soft drawn...
