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 | - | Remote monitoring and control for up to 8 generator sets via high-speed network. Enables paralleling a group of EMCP 4.4 equipped generator sets to a single utility source. |
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 | - | Emergency standby, island, utility paralleling |
