Technical Summary

Configuration - Application-specific switchgear with control logic designed to meet any customer's sequence of operations. Examples are 3+ Utilities, CHP applications, complex load shed schemes, etc - Configurable PLC based switchgear capable of controlling and monitoring multiple generator sets, tie and load breakers in conjunction with downstream transfer switches for standby or emergency applications
Modes of Operation - All modes of paralleling generator sets to each other and to other sources (utility, alternative fuels, wind, etc) can be supported. Caterpillar generation and control experts can design and program the most complex power schemes to meet your critical pow - Multi-unit Island and multi-unit standby mode with optional redundant controls and components.
Application - LV and MV ( 208V - 38 kV) 50 / 60 Hz - LV and MV (208V - 38 kV)
