@EddyWirbelstrom, Sir Thanks alot for the effort and explanation.
If we go to any TCC and select the curve of any relay, right click, click Selected device TCC Settings (see attached Image), there is Time Multiplier and Current Multiplier. What is the importance of this and how we can calculate...
Dear All
Being new user of SKM PTW, I have the following questions for the attached files.
In the attached file named: "VAMP-40 Settings" the relay component editor is shown. The first Parameter is I> (0.1-5 x PA), what PA stands for? The second parameter is " IEC Normal Inv." and in the...
In the attach link you can see that the value of I30cycSLG is 2231.75A. The FLA of Chiller#1 is 873.6A at 380V with starting inrush of 5.88 x FLA.
Now the starting inrush for Chiller#1 is much higher then the minimum fault current (I30cycSLG i.e. 2231.75), so I want to now at how many times of...
I have carried out ANSI 30cycle Short Circuit Study in SKM but the Values of ANSI_30cycle_3P & SLG is 20A & 12A respectively at 13.8kV. The utility is rated as 500MVA.
What might be the problem.Why the Value is so small? I cannot do the settings for the relays unless I rectify this.
Hello Everybody....
Power System Studies and especially Relay coordination and settings is my passion. But its very unfortunate that even in today's age of internet, guidelines and help on these topics is not available. Like for Relay Coordination, only one standard document "ABCs of...
Hello Everybody
I am conducting a Relay Coordination Study on SKM. Before this I have worked on ETAP.
While working on SKM, there are too many attributes for Shortcuits based on IEC and ANSI. Which short circuit attribute I shall choose for my study.
Thanks
