Be Proactive, Not Reactive When It Comes To Your Maintenance Repair Operations

Every year, the rail industry spends billions of dollars to improve the national infrastructure. For example, American freight railroads spent $28 billion in 2014, and a projected $29 billion in 2015 on infrastructure and equipment. Although new projects draw the most attention, the majority of spend is on routine maintenance repair operations to ensure continuous safety and efficiency of the railroad system. There is a definite correlation between the increase in rail network investments and enhanced safety performance.

After a recent US passenger train accident last month, the Federal Railroad Administration issued a safety advisory for passenger railroads. The railroads are recommended to use an existing technology called Automatic Train Control (ATC) to alert trains appearing to be travelling at an excessive speed, in hopes they reduce their speed as they approach a curve or bridge. (On May 12, 2015, an Amtrak passenger train carrying 243 passengers and crew members derailed killing eight and injuring more than 200. The train was travelling well above the allowable speed limit for that area).

EMI Noise Mitigation – A Key Factor to Control Panel Optimization

One of the core issues affecting the performance and reliability of industrial EMINoise-sourcevictim control systems is electrical noise. It can cause field device misreads; devices to fail, reset, or enter a fault state; equipment damage; or signal retransmission that inflicts communication delays. The topic of mitigating performance issues caused by electrical noise is wide ranging, but we’ll look at three topics here: the types of Electrical Noise, the types of problems caused, and a multilayered approach to EMI noise mitigation.
