LEGACY CONTROLS FORUM, NO. 6 IN A SERIES By Luke Williams, PE, consultant www.geLegacyGasTurbineSupport.com An MS7001B gas turbine with Mark I Speedtronic™ controls and SCR static exciter-regulator experienced overcurrent damage to its exciter on a normal startup. Operators think the overexcitation event lasted for several minutes. However, an overexcitation alarm was not received and the

If you’re managing MK4, MK5, or EX2000 platforms, this Technical Information Post (TIP) from AP4 Group demands your attention (Download here). These “classic” control systems rely on EEPROMs—and in the case of MK5 and EX2000, the U9 chip—to store essential software and configuration data. Failures of these components, increasingly common in systems over 25 years

To some, here’s the distinction between reliability and resiliency: Reliability is avoiding a punch; Resiliency is recovering as quickly as possible from a punch. Aging assets, such as those with older turbine models, are likely going to take more punches than they avoid because the resources to avoid the punch are devoted to newer, more
With all the sophisticated gas-turbine inspection technologies available today—including ultrasonic, eddy current array, and phased-array ultrasonic—one might think the borescope had lost a step in status. Nothing could be further from the truth. Borescope capabilities have improved dramatically over time and they put your eyes right into the guts of critical plant equipment—to warn of
Borescope inspections often more important than ever Read More »
