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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
