Hi,
I'm designing a pilot project for energy storage unit based on an induction generator coupled with a frequency drive.
there are also several large motors driven by VFDs as well so we are talking about approximately 2300kVA peak load on the transformer.
the problems are:
1. load varies...
Hi Colleagues,
Today wind turbines can go up to even 12MW at low voltage - 0.69kV.
this sounds very challenging with regards to low voltage equipment.
how would a connection of a 12MW generator look like?
at 0.69kV we are talking about 12kA current. biggest LV breaker and LV bus I know are...
Hi All,
The question is regarding an electrically excited synchronous generator.
Consider that this generator is not connected to the grid and thus not locked with the grid frequency.
This generator is spinning at variable speed and gets constant and similar excitation current
meaning that the...
I want to connect to 2 SEL700G relays at the same time to monitor their readings online.
I can't seem to be able to open 2 instances of the quickset software.
any suggestions?
Hello,
I'm looking to standardize a practice for cable abandoning in my company.
is there any common practice for this?
I'm specifically interested in cables that were cut at the end point (at a transformer terminals for example).
do you short the phases?
do you ground the phases?
maybe both...
