The ASCO 4000 Series Generator Paralleling Switchgear can start, synchronize, parallel, monitor and protect emergency, standby, and prime power systems. 4000 Series Generator Paralleling Switchgear power management provides the most powerful, reliable and advanced digital control by separating the control of generators from load distribution control, and independently managing each.
Generator load demand maximizes the efficiency of generator usage. After a stabilizing time delay, a generator may be started and connected to the main bus for high demand, or unloaded and shut down for low demand. This conserves fuel and reduces maintenance requirements by operating fewer generators at a more efficient level. Bus load optimization determines the capacity for adding loads to the bus. It evaluates system utilization, based on available capacity and distribution load ratings.
Effective power management derives from the assignment of unique and structured priorities to distribution loads, which are controlled by the 4000 Series Generator Paralleling Switchgear via transfer switches and/or electrically operated distribution circuit breakers. Because the 4000 Series Generator Paralleling Switchgear can control up to 32 individually prioritized transfer switches, individually controls each transfer switch per its unique priority, and allows operators to change priorities run-time, the ASCO 4000 Series Generator Paralleling Switchgear provides unsurpassed distribution control.
