I am working on a project that involved cable calculations for a duct bank. My modeling software defaults to 35 deg C for ambient earth temperature and typically I keep that value so that the design is overly conservative. Usually duct banks I am involved with are less than a hundred feet...
I have questions about a couple of the equations in IEEE 605-1998 and was hoping someone here might be able to shed a bit of light. In section 11.1 where they calculate bus deflection there seems to be an error in some of the equations. For discussion purposes I will look at equation 14 and...
I am working on a spreadsheet for calculating bus and insulator loads for substations in the US. These calculations are based on IEEE 605-1998 Design Guide for Subsation Rigid-Bus Structures.
I have gotten down into Section 12.1.5 and there is an equation (35) for "total cantilever load acting...
I have recently been testing EMI on a permanent magnet generator and observed something I can not explain. I am not extremely familiar with PMGs so I thought I might see if any of you guys have seen anything like this before. I was operating the generator to provide 400Hz output and was...
