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
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
