An alarm condition used by the EGCP-2 for various alarm settings which will cause the audible alarm relay output to energize when reaching or exceeding the alarm parameters. Automatic Sequencing The automatic addition, or subtraction of generators to/from the load based on predetermined load levels being crossed for specific periods of time. Automatic sequencing is a function of a multiple generator system that is operating in load sharing mode isolated from the mains, of process control mode in parallel with the mains.
Automatic Voltage Regulator
A device that controls the field excitation of an AC generator in such a way as to maintain a specific voltage level over the operating load range of the generator. The EGCP-2 control biases the voltage setting of the AVR to voltage match during synchronization and to control reactive load during load share and mains parallel operation. Base Load A term used to describe a generator loading condition in which the generator is paralleled to another source of power, typically the mains, and loaded to a fixed kW level. The generator maintains this kW level regardless of load on the Mains.
A device used to connect one power source to a load
or to another power source. Breakers can be either manually or automatically operated, and will usually contain overcurrent protection. The EGCP-2 controls motorized breakers by issuing a momentary breaker close output to energize the breaker coil, and a separate breaker open output to shunt trip the breaker to open it. Contactor A device used to connect one power source to a load, or to another power source. Contactors are typically automatic in operation, and are energized for closure from an external source. The EGCP-2 controls contactors by issuing a contactor close output to close the contactor, and removing this output to open the contactor.
