Design 3 in 1 module of a drawout MCC panel

Abstract

Low-voltage motor control center (MCC) are numerous and consume portion of maintenance and operator interaction in an industrial power system. The extensive human interaction withs these low-voltage circuits makes a low-voltage MCC significant potential hazard. Due to which The large number of low-voltage MCC panel significantly more human interface time with the low-voltage MCC equipment than with medium-voltage MCCs and switchgear. This is modern protection and control systems derived power systems have much to offer solution of low-voltage MCC systems. Proactive maintenance indicator based on load characteristics and motor start characteristics, and thermal measurements are described. Sequence of events are to Time synchronization modern Ethernet-based protocols, sequence of events records oscillargy monitoring and alarming for protection functions, and other previously features medium- and high-voltage protective relays are available in modern low-voltage MCC protective relays. Increased safety in the form of advanced protection elements and arc-flash detection are now also available. This paper focuses on the philosophy of a comprehensive low-voltage MCC protection and control system.
