Hi All,
Can someone please tell me how to soften black rubber?
I have a window cleaning squeegee with a rubber blade. I didn't notice at the time of purchase that the rubber blade is really hard. It's not old, hardened rubber. But, just too hard to wipe across my car windows.
Thanks
Andrew
Hi All,
I have been dropped into the deep end of reliability analysis and probabilistic planning for power systems (transmission and distribution) and need to get up to speed very quickly.
I have read several IEEE papers on the topic and am now starting to understand monte carlo analysis and...
HI All,
what is the difference between "Newton Raphson Classical" and "Newton Raphson Current Loop"?
The NR Current Loop method seems to solve much more easily, especially for my power sytem that has voltage problems in a particular area. Actually the NR Classical won't converge, but the NR...
Hi everyone,
I've been running power flow models and can't explain what I am observing and how to stop it. Can anyone help me understand what is going on?
This is a real life situation. I have a transmission circuit of 100km with a power station at each end.
At one end the voltage is set...
Hi all,
I am using digsilent and it provides a check box titled "LV-side, phase 2 internally grounded" when I create a single phase Y-D two winding transformer.
What does it mean to have a delta winding that is "phase 2 internally grounded"?
thanks heaps.
Hi all,
what does this phrase mean "a transformer with 5% impedance'? Is it just the p.u. impedance? Also, what are the formulae for calculating that percentage impedance?
Thanks,
Andrew
Hi All,
I need to purchase a second-hand tan delta measuring bridge that can measure tan delta at 12kV and 50/60Hz.
Does anyone know of some suppliers of second-hand measuring bridges?
Thanks for the help
Andrew
