    Max load on a Hochstadter type of cable?

    Thanks for the tip Desrod2! Unfortunately I don't have access to such software. Basically, I'm in a need of a rough (but well grounded) guide of what I could load on that cable given a given conductor area. UHEngineer

    Max load on a Hochstadter type of cable?

    Hi all! I've got a really old 36 kV copper cable of Hochstadter-type, and no data sheets available. Anyone knows a decent table that can be used for max load of this cable? Or some resources as to which approximation can be made? The closest I have is looking at a load table for a...

    YNyn zero sequence of neutral earthing

    Thanks for the link ScottyUK. But I am looking more for a description of how this can be applied to fault calculations specifically. Consider a phase-to-earth fault on the secondary side - how would you model the zero-sequence impedance for that case (with this particular transformer)? Would...

    YNyn zero sequence of neutral earthing

    Hey all, currently working on a 145/40 transformer that is earthed (neutral) directly to the ground on the upside and through a 500 Ohm resistor on the downside (i.e. the neutral). My questions: - how to model the zero-sequence impedance correctly on the downside, with regards to the 500 Ohm...

    PSS/E Short circuit analysis output question

    Since I'm completely new to PSS/E I have a following question about the output of this file. I am analyzing a smaller network that is connected to a larger network through a transformer. A short circuit analysis is made on the bus of the larger network (meaning, I need the equivalent impedance...

    Fault analysis in an industrial network - software?

    Hi all! I have a coming up project to analyze an industrial network for fault analysis and relaying. Can any of you recommend some good software to accomplish this? Since I am new in the position, I don't have any prior experience with software analysis. There are many different vendors to...
