CCJ ONsite’s coverage of technical highlights from the Generator Users Group’s Third Annual Conference, held in Phoenix, Aug 27-30, 2017, concludes below with the third and final installment of lessons learned and best practices shared among attendees. Presentations and discussions are arranged in these five sections: Stator frames and magnetic cores. Stator windings and bus systems.

Generation assets in competitive markets must perform at a high level year in and year out to meet their contractual obligations. Failure to embrace a philosophy of “continual improvement” in plant operations means it’s only a matter of time before the competition will eat your lunch. The focal point of continual-improvement efforts typically is the

Paul Tucker called CCJ’s editorial offices a few weeks back with a generator experience to share with users. Say Whaaat? Tucker is well known to engineers and technicians at power and process plants for his ability to identify the root causes of turbine problems. There isn’t much he hasn’t experienced in his 50 or so

You don’t hear much at industry meetings these days about physical security of power generation and delivery infrastructure and personnel. Cybersecurity topics get most of the attention. But that doesn’t mean work on physical security solutions has stopped. Certainly not. One recent development concerns transformer protection. Six years ago (Apr 16, 2013), you may recall,

There are numerous instrumentation systems used in attempts to assess the condition of powerplant electrical equipment. The library of papers about them is vast. But papers discussing detection of failing electrical connections inside generators or bus systems are limited in number, Consultants Clyde V Maughan and James E Timperley told the editors. The focus of

In successful powerplant projects, either in the early project bidding or the engineering execution stage, before designing any water distribution, production or treatment system, you must know the water. The only way to fully understand the water type and its characteristics is with a thorough study of the water analysis report, says Wendy Wong, a

Turbine Tip No. 5 from the PAL Turbine Services O&M solutions library applies to General Electric Frame 5 models L, LA, and M equipped with Oilgear fuel pumps, Frame 5N machines with New York Air Brake pumps, and 5P and 5PA gas turbines with Roper Pump Co equipment. This is a follow-up to Turbine Tip

The sixth annual meeting of the European HRSG Forum (EHF), May 14-16, 2019, Athens, Greece, was a global event with representatives from 17 countries. There were more than two-dozen presentations on the agenda, plus a workshop on water chemistry. CCJ ONsite’s recent report on film-forming substances (FFS), a topic discussed at all recent HRSG conferences,

The negative impact of moisture on electrical equipment has been a serious concern since the beginning of the industry. Most senior plant personnel have had experiences with low insulation resistance (IR) and low polarization index (PI) values that have extended an outage. One example provided by subject-matter experts Neil Kilpatrick, GenMet LLC, and James Michalec,
