GEs AKD20 Low Voltage Switchgear has unique and innovative features, which by design, greatly reduces the arc flash incident energy (severity) and the likelihood (probability) of its occurrence. These features give you the required protective and preventive control measures and forms as an integral part of the design of the switchgear. |

Modern power distribution systems, such as the common double-ended substation, contain multiple power sources integrated within one system. This presents significant complexity to the designer attempting to design a protection system that will not be fooled by circulating neutral currents. This paper describes how the âSingle Processor Concept for Circuit Breaker Protection and Controlâ provides ways to address this sensing problem. |

The authors explore a protection and control architecture based on a single processor that provides all the protection and control functions for a line up of low-voltage switchgear. They demonstrate how this changes the paradigm from individual circuit protection to system protection, while cost-effectively and significantly increasing system reliability and protection. |

In this paper, the authors explore a protection-and-control architecture based on a single processor that provides all the protection and control functions for a lineup of low-voltage switchgear. How this method of protection changes the paradigm from individual circuit protection to system protection, while cost-effectively and significantly increasing system reliability and protection is discussed. |

In this paper, the authors discuss a unique approach to low-voltage switchgear protection and the process of transitioning this concept to a realworld application. The paper describes the architecture and functionality of this approach and explains how a centrally controlled system can provide advanced monitoring and protection functions much more effectively than existing systems. |

GE’s zone selective interlocking with instantaneous protection (I-ZSI) has been developed to provide safety and selectivity at the same time, all the time. Zone selective interlocking schemes are limited to circuit breakers that are a short distance of each other. Selectivity between a circuit breaker and its downstream current limiting device without control signal connections between the two have also been developed. GEs waveform recognition (WFR) algorithm extends the zone of selectivity from the low voltage switchgear down to the low voltage MCCs, panelboards and any other equipment and at the same time reduces the arc flash energy at this equipment to a low level. This feature has no distance limitation. |
