Hello all,
I’m trying to find the inrush current a new 12 (24MVAR future) 115kv Capacitor bank. I found the formula:
I(max)=1330*?(KVAR/LS) for 60hz,
Where, LS is the system inductance in microhenries.
Now, I know that:
Xl=2?fL=377*L
Or...
L=Xl/(2*pi*f)
So my question is, should I just...
I am curious to see how other people incorporate physical separation in primary and secondary line relays, I'm not talking about separate DC, CTs, etc.
On 115kV to 230kV transmission lines, is it necessary to use different panels?
If the two relays are on the same panel, is it best to put...
What is the proper way to show Control Switch contacts on DC Control schematics?
Is it best to:
1) show all contacts as a simple open contact symbol, having a contact development show which contacts are closed during different switch positions, labeling next to the contact what state the...
I am fresh out of college and entered a Substation/Transmission Engineering position, where currently there is a debate on Breaker Fail philosophy.
The question is:
On a radial 115kv substation (designed to expand to breaker and a half scheme) is it best to:
1. Use a separate 50BF relay...
