IRG Power Systems goes beyond just resourcing your parts and supplies. With many locomotive spare parts no longer available or being obsolete and/or inactive from the OEM, IRG Power Systems can provide manufacturing services including reverse engineering to help a locomotive owner solve their spare part challenges. If needed, we can supply replacement components of our own manufactured items for Electro-Motive Diesel., General Electric, and Alco locomotives. (EMD), Wabtec-General Electric Transportation (GE), ABB, Siemens, and Alstom. We commonly partner with electric apparatus repair shops to serve industrial locomotive operators who need help with their traction motor, alternator, generator, and locomotive electrical systems maintenance.įor years, our company has been both suppliers to, and customers of the primary locomotive manufacturers including Electro-Motive Diesel Inc.
We understand the responsiveness necessary to keep your locomotive assets in production. IRG Power Systems focuses our service on industrial locomotive applications at mines, steel mills, refineries, and utility power plants. Applied incorrectly, either can lead to major headaches.IRG Power Systems supplies all the Locomotive New and Rebuilt spare parts and components that railroads and shops need for the repair and maintenance of GE, EMD and Alco locomotives. When applied properly, both medium-voltage circuit breakers and medium-voltage contactors should provide decades of reliable service. In contrast, users in the process industries have long favored the use of fused contactors for such applications and have enjoyed long service with lower maintenance costs. As a result, these applications have had higher maintenance costs than if medium-voltage fused contactors had been originally. As these stations have aged, and station operation has changed from base-load to peaking service, many of these motor-starting circuit breakers have experienced total operations well in excess of the endurance required by the ANSI standards. Historically, circuit breakers have been used for medium-voltage motors in certain industries, especially in utility generating stations. Reduced voltage starting is needed to reduce starting duty (and voltage fluctuation) on system Process continuity compatible with fuse replacement timeĮ. Switching is very frequent (i.e., daily or several times per day) very high endurance (100,000s of operations) is neededĭ. Continuous load current is low or moderate (i.e., smaller motors or transformers)Ĭ. Typical loads: motors, smaller transformersī. Medium-voltage NEMA Class E2 controllers (fused contactors) are favored when:Ī. Reduced voltage starting is not needed (RV starting complicates switchgear bus arrangements)Ģ. Process continuity is critical (i.e., no time for fuse replacement)į. Switching is not very frequent (i.e., weekly or monthly) high endurance (1000's of operations) is satisfactoryĮ. Continuous load current is high (i.e., larger transformers, larger motors)ĭ. Ratings required exceed those of contactors (360A or 720A at up to 5kV, 360A at up to 7.2kV)Ĭ. Typical loads: transformers, capacitors, larger motors, generators, distribution feedersī. Medium-voltage circuit breakers are favored when:Ī.
