Advanced Event Analysis Tutorial Part 1: Questions

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.

Event Analysis Tutorial Part 2: Answer Key

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.

RTAC System Performance

The SEL-3530, SEL-3530-4, and SEL-2241 Real-Time Automation Controllers (RTACs) are ultrarugged remote terminal unit (RTU) and programmable logic controller (PLC) systems. An RTAC can operate as the controller for the SEL-2240 Axion, which is a modular I/O system where up to 60 modules can connect to a high-speed, deterministic EtherCAT network. We performed processing analysis and testing to determine the performance of the RTAC with the Axion I/O system. This paper summarizes these tests results and provides recommendations to determine an optimal processing cycle time for any particular application.
