500 MW Generator Failure: Lesson Be Observant

          A 500 MW generator failed catastrophically, it had an internal short that resulted in a phase to phase short. The generator stopped so suddenly that it sheared off 24 2 ½” bolts in the coupling between the generator and the turbine. The problem was traced to the phase leads resonance shifting to 120HZ as the generator aged. This problem resulted in the annual testing of the phase leads for the unit that had the failure and also on its sister machine. One of the key lessons learned during many hours of testing these generators was that [...]

Aircraft Generator Opportunity

Most military airplanes have extensive avionic systems, such as radar and radar jamming systems. The avionics are powered by small on-board generators. The size and weight of these generators are critical so they are designed to be very small and lightweight, while providing adequate power for the aircraft. After a set number of flight hours, these generators are removed from service and must be rewound to reduce the chance of failure. Our company has rewound many of these generators thanks to Don Morris and his many years of expertise. Don provided training and has been a mentor to Stephen Clippinger, a [...]

Hydro Electric Power Plant Generators

 The first hydro-electric power plant was commissioned in 1882 in Appleton Wisconsin. It was a collaboration between the owner of Appleton Paper and Thomas Edison. Since then there have been many power plants built to convert moving water through an impeller that turns a generator rotor to produce electricity. This is the original “green power” and was way ahead of solar and wind power to produce electricity without burning fuel. Horner Industrial Group began marketing efforts in hydro-electric power over 10 years ago by attending hydro-electric power trade shows. We quickly learned that most of the power plants are run by [...]

High Temperature Generator Project

We received a phone call one day from a Phd. Mechanical Engineer working on-site at an Air Force Base. I soon realized that this was a phone interview to see if our company was qualified to help him on his jet engine projects. After working together for about a year, successfully fabricating custom parts for the jet engine test stands, the engineer referred our company to a Phd. Electrical engineer who asked if we could help him develop a high temperature generator. On a jet fighter plane, space is at a premium as there is a need to produce more electrical [...]

Hydro Generating Station: Oregon

In January 2018, the Springfield Division was contacted by a large electrical contractor to quote a hydro generator collector ring assembly repair and replacement. The contractor received a RFQ to replace the Hydro Generating Station, in Ashland, OR, excitation system. Included in the work scope is the removal, refurbishment, and installation of the generator collector ring assembly. By the end of February, we received a PO to perform the work. A trip in May was scheduled for Jim Delawder & I to job walk thru at the hydro generating station. The job walk confirmed the generator collector ring assembly location on [...]

Horner Industrial Group Helps Manufacturer After Dayton Tornado

On Memorial Day, May 27th at 11:30 PM, an F-3 tornado packing winds up to 140 MPH hit several homes and businesses in Dayton Ohio. One of the businesses was a manufacturer of specialty motors for the railroad industry. The storm tore off half of the roof and destroyed the walls, leaving the steel structure intact. (see photos) Two weeks earlier, Dave Whited ran into a previous co-worker that he had not seen in 20 years. Corky Compton was a winder at our Springfield repair shop prior to leaving our shop to be the winding supervisor at the motor manufacturer. Dave [...]
