Now, standards such as IEC 61508 provide a framework from which new safety risks can be managed. This paper simplifies the complexity of integrating new devices into existing grid networks by explaining how to implement IEC safety and maintenance standards. Examples are presented for how to minimize cost and maximize safety benefits. 998-2095-02-21-14AR0 Impact of IEC 61508 Standards on Intelligent Electrical Networks and Safety Improvement Introduction Over the last several years utilities have replaced electro-mechanical technologies with new programmable electronic systems. While utilities have benefitted from the new technologies, it is difficult for operations personnel to determine every possible failure scenario and to predict issue-related network behaviors. The stakes are high as the tolerance for medium / high voltage electrical network downtime continues to erode. Costs are too high for both customers and utilities when network failures occur. In addition, the need to maintain safe network operation is a growing concern given the increase in complexity of the emerging networks. These programmable electronic systems (also referred to as Intellige nt Electronic Devices or IEDs), are characterized by failure modes that are different...
