Short Circuit & Time Current Coordination
Short Circuit & Time Current Coordination
ensure safe & reliable electrical system operation
Short Circuit Analysis
Square D Power System Engineering performs computer-based short circuit analysis for all types of industrial and commercial electrical equipment to calculate fault levels throughout the system and address the ability of the protective devices to respond under short circuit or overload conditions. Where underrated or misapplied equipment is identified, we provide recommendations to help you adhere to the requirements of NFPA, NEC and other electrical industry standards. A short circuit and coordination study is vital to ensure the safe and reliable operations of your electrical system.
Advantages:
Square D Power System Engineering performs time-current coordination analysis with the aid of computer software and the study includes the determination of settings, ratings, or types for the overcurrent protective devices supplied taking into consideration service continuity and system protection goals.
Advantages:
