We have critical loads driven by DC motors. Almost all are fed through the DCS600 ABB drive type.
Question: is it usual to run field protection testing of the motor? I mean, primary current injection to test OC and OL response of the drive embedded protection system.
Thank you for your time and...

dafo74, yes, it is from Siemens (DIGital SIemens, I guess)
jlazucena & DiscoP, thank you for your inputs.
Gentlemen,
in the medium voltage range, vacuum circuit breakers seem to have the largest share of the market nowadays. May I have your opinion about their performance compared to SF6 circuit breakers, in terms of switching and maintenance characteristics? Do anyone know of any 'independent'...
DanDel, thank you for the script offer, it will certainly help me since I have access to Auto CAD.
Bung, thank you for your comments, Mathcad 7 is the latest version I remember using for creating and plotting custome curves (unfortunately, no longer have access), among known commercial packages...
We need to plot customized protection curves on TCC charts and would appreciate links to download blank double-logarithm charts.
Thank you all for your assistance.
