Improper relay logic threatens your electrical assets and investments
After all of the possible hardware components have been moved into relay logic, self-monitoring and diagnostics provide a means to alert the operators of system component failures prior to an entire system failure or misoperation occurring. Previously, the only way to determine whether or not the system would function as intended was through manual testing, often requiring a complete system shutdown.
2. Event-recording capabilities
Microprocessor-based relays offer built-in event recorders, capable of capturing and time stamping event information at one millisecond resolution. Following a fault, the relay can reproduce a report summarizing the sequence of operations prior to the event. Information collected by event recorders can include trip sequence, the amount of time a breaker was open, where the fault occurred, nature of the fault, pre-fault conditions, and power quality monitoring waveform. These details expedite troubleshooting and can help operators more quickly identify the root cause of a fault. Ultimately, faults are cleared quickly and safely, minimizing costs and downtime.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
