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.
