Insulation Testing of Turbo Generators
Wednesday morning-1/2 day course
Douglas Conley is an industry expert in insulation materials development and electrical testing of high voltage windings. Currently he is a Fellow Engineer at Siemens Energy in Charlotte, NC with over 35 years of experience. His contribution to IEEE working group over decades is essential to standards development
Turbo Generators are designed for operation over a long period of time. High quality stator winding insulation is an important factor to achieve the expected reliability and forced outage rates. This course will provide basic description of stator insulation components and systems. It will include an overview of technical principles, applications and testing requirements outlined in IEEE 56, IEEE Guide for Insulation Maintenance of Electric Machines, along with some points from IEEE 4, 43, 95, and 286.
- Who should attend:
- Engineers who require testing and inspection of electric machines especially turbo generators
- Maintenance, Service and Technical staff responsible for electrical machinery
- Management of any level
- Key Benefits:
- Provide a basic description of stator insulating components and insulation systems
- Describe the types of tests for machine insulation
Additional investigative tools such as: microscope, borescope and other visual and investigative methods
Review of typical parameters and example results
Provide pros and cons of various tests
