Engine Generator Integrated Switchgear

Caterpillar offers standard paralleling solutions, which can be provided in a wide variety of market applications. The Engine Generator Integrated Switchgear (EGIS) product line provides a standard paralleling system (circuit breakers, bus, and controls) using pre-engineered structures in an integrated controls / switchgear lineup. EGIS allows for operating generator sets in pre-configured Emergency Standby, Prime power and Parallel with Utility configurations. The modular EGIS system utilizes the industry proven Caterpillar EMCP 3.S dedicated controller to perform synchronization, power factor control, load sharing, and system monitoring. The user is able to monitor and control the system through an industrial touchscreen HMI.
