Every relay setting, every breaker rating, and every protection coordination curve should be backed by rigorous analysis, not inherited assumptions or guesswork. PACS employs highly experienced power system studies engineers who deliver the analytical foundation your network needs to operate reliably, safely, and in full regulatory compliance.
Our studies have directly resolved live operational problems, including chronic nuisance tripping at the St. Regis Hotel Katara and Qatar Foundation industrial substations, and have informed the protection design for some of Qatar's most complex commercial, district cooling, and high-security facilities. When we deliver a study, we deliver a complete analytical narrative: the network model, the calculations, the settings proposals, and the documentation required for Kahramaa approval, all in one coherent package.
