This white paper provides both theoretical and real-world examples with questions that can be used to gain experience with symmetrical components. The full solutions to these questions can be found in the white paper "Tutorial on Symmetrical Components, Part 2: Solutions."
Event reports have been an invaluable feature in microprocessor-based relays since the initial introduction of the technology. The days of unknown root cause for an operation, lengthy outages, or unexplained test results are largely over due to this tool and the ability of engineers and technicians to use it. We must practice to become proficient at analyzing event reports. This session provides real-world event examples, time to evaluate them, and solutions.
Event reports continue to be an invaluable feature in microprocessor-based relays. Some events are relatively straightforward to analyze, and others require experience and considerable knowledge of the power system and protective relay system in order to find root cause. This session provides several advanced real-world event examples, time to evaluate them, and solutions.
This white paper provides both theoretical and real-world examples with questions and solutions that can be used to gain experience with symmetrical components.
This paper describes how SEL software-defined networking (SDN) can significantly reduce the time and effort required to collect data and provide evidence for CIP-007-6 R1.1 and CIP-010-2 R1.1.4 compliance. It also describes how SEL SDN can assist with meeting NERC CIP-005-5 R1.1–3 requirements [3].
This white paper addresses the design considerations for modifying transformer protection at an existing nuclear station and the SEL equipment that can be used to implement that design.
This paper discusses how the SEL-735 Power Quality and Revenue Meter exceeds the nonsinusoidal test requirements for ANSI 0.1 accuracy class compliance. It also illustrates why the SEL-735 is highly qualified for revenue metering applications in today’s challenging power system conditions.
This white paper describes how to use the SEL Real-Time Automation Controller (RTAC) to build an automated system to continuously monitor and validate many of the components identified in the NERC PRC-005 standard.
