Project Description

Sanitation plant system, which includes five 12kV substations, a 12kV cogen plant, a 12kV standby power plant (3 generators), and many hundreds of 480V breakers was in need of a complete system modelling and relay settings updates.


PRE modelled the entire system and performed the short circuit analysis and arc-flash analysis for the entire facility. We also prepared medium voltage relay settings, and low voltage breaker settings for the entire facility.
