I am searching for information with regard to assessing the need for increased winding clearances in HV generators due to higher altitude siting, due to higher potential for corona discharge damage.
Clearly the atmospheric pressure will be reduced & hence the resistance to discharge reduce over...
Could anyone provide enlightenment on a problem I am facing with a Gas engine driven 11kV genset?
We have a gas engine, direct coupled (frame close coupled) to a 11kV 2/3rds pitch 3250kVA generator.
Connection is in start with a floating neutral.
Customers load lead connections are made in...
Can anyone suggest reading material or have some knowledge of investigating a main field shorted turns problem on synchronous machines?
I have a 3 phase synchronous machine, but am concerned that at some point during operation, it gets into a slip operating condition, such that it effectively...
Hello,
I'm an electrical engineer in need of some direction pointing!
Has anyone got information on high horsepower natural gas engines, where a study of torsional analysis has been completed to discover the effect of cylinder misfire on the power provided to a shaft driven, direct coupled AC...
Could some learned gentleman please advise where I might obtain reference material for HV DC testing of rotating electrical machines.
It is recognised practice to verify the condition of a synchronous generators main stator winding insulation system with a High Voltage AC withstand test at (2x...
Could someone provide information with regard to the theory of how HV elecrical impulses travel in transformer motor and generator core steel laminations, from the windings through the insulation coating?
I am presently involved with form wound winding interturn tests and have noticed that a 0...
I am looking for authoritive 'best practice' information on generator output connections, i.e. where a contractor would use something akin to steel wire armoured flexible cable to connect through a bushing box onto the generator output bushings. This is primarily for generators up to 13.8kV, in...
I'm working on a dissertation comparing static & rotating excitation systems, design, performance characteristics, cost & reliability. However, all my experience is with brushless rotating excitation systems on small salient pole synchronous generators.
Could someone point me in the right...
