Ansi triping band for 250VDC system
(OP)
Dear all,
What is ANSI tripping band voltage for 250VDC system.
I know that ANSI tripping band voltage for 125VDC system is 70V to 140V. but do not know tripping band for 250VDC system.
I am working in 145kV ABB breakers which has tripping system of 250VDC.
is there any way, any link, where I can get this information.
Thanks in advance
