More than ever, submetering is being applied in industrial as well as the traditional commercial and residential applications to encourage conservation and increase productivity. This article will describe what it is, why it's important and how to effectively apply it. |
Date: | Size: 133011 | Publication Number: SUBMETERING |
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. |
Date: | Size: 1032032 | Publication Number: DER-037 |
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. |

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. |
