COMTRADE file.
(OP)
Dear All.
I have several programs for COMTRADE files evaluation ( ABB, Siemens).
Only in one of them, I have option for build graph of frequency. But it's request some math. formulas and not so friendly.
One of my customer request some more easily tool and with
option of df/dt presentation.
What SW recommended?
Thank you for your help.
Best Regards.

RE: COMTRADE file.
Any suggestions on how to calculate frequency from the data?
RE: COMTRADE file.
I provide several tests on several tools ( Jghrist, sorry, I used your file for test also, it's file from US relays, that I have on this moment).
TOP is good tool, have several intresting options, but also have several serios disadvanteges ( of course, according to my requests only).
MathCAD, intresting option, but not so real for me, license price and devolpment time, for one customer only, isn't option.
Only one tool have option for the frequency calculation, but it open files from European relays and not open file from Backwith relay ( indicated: probblem with COMTRADE file).

I used your file ( COMTRADE format).
This file was open in TOP SW, but not in ABB (Swiss).

RE: COMTRADE file.
Used files from European and US ( Backwith) relays.
Used SW : Distdraw, WinEVE, Wavewin, Sigra, TOP.
Files from European relays was opened in all 5 SW's.
File from Backwith only in TOP and Wavewin SW.
Two ABB tools and Siemens tool indicated (NOT COMTRADE FORMAT).
I also see some term: IEEE COMTRADE standard.
Folks, it's not some comercial test, only for understanding.
Could you please add some information and if possible send some COMTRADE files from SEL and GE relays.
Regards.
