impedance diagrams

[tonyflair]

I'm performing a fault study on a small distribution system and I was wondering if anyone new of software that would generate impedance diagrams so that later, relay settings can be determined.

I've determined the positive/negative and zero sequence impedance at a variety of locations throughout the system.

Thanks in advance

Aspen One-Liner will put impedances on a one-line. See

SKM's Power Tools (Dapper) can include any system parameter on the oneline diagram. See

i propose the tcc121 and kubsplus from siemens.
you will find both by searching siemens sites. Good and simple.
