I fully support the sanity check on software because of the garbage in garbage out issue, but more importantly if you are doing fault calculations which are determining switchgear duty you are potentially putting someone at risk. If you get it wrong, switchgear is liable to fail explosively if...
thanks for the response, I am familiar with the use of galvanised pipe for electrodes, but the issue I am dealing with is diiferent in that the piece of pipe is forming part of a continuous electrical circuit within a substation i.e. there is significant power flowing all of the time as opposed...
I have encounted the use of galvanised steel water pipe as a connection to a disconnector in a lv substation, has anyone had experience of this and knows a reference to calculate the current carrying capacity.
thanks for your responses, they are helpful. However I should have explained a little more, I am setting some power system problems for engineering students and I wanted to do exercises in comparing supply options without going into detail parameter calculations. What I would like are examples...
has anybody got a ready reference to typical transmission line parameters e.g. for given voltage and current rating I want to get resistance, reactance etc.
