You could propose some expensive step and touch potential measurements. How can you install anything on property you don't own. Paving the area would solve it till it got dug up.
It so close it can not be isolated. IEE665 states you don't have to bond grids if the separation is more than 200M.
But if you consider if it was a green field site you would not do anything beyond the power plant property line, which would be a grounded fence..
What waveform do get at 0 Hz, DC? How do they get starting torque? I have been trying to find a technical explanation of how this works.Do you have the field connected?
It seems that VFDs can start synscronous motors from standstill. Not sure about the special case of Generator Solid State Starting devices. Anyone doing it?
Basic theory about synchronous motors, they are not inherently self starting and usually start as induction motors using an embedded squirell cage in the rotor.
Read page 16. A sychronous motor can not start from standstill, so the turning or barring gear gets it rolling
and the VFD matches the speed frequency and applies the field. Then it becomes a synchronous motor.
Thanks Scotty. The GE Literature is much better than for the ABB megatrol.It seems then the barring low revs are matched by the VFD to produce synchronous motor operation. I note the GE is water cooled and ABB aircooled.
To operate as a synchronous motor it needs to start as an induction motor or be brought up to near synch speed by some other means. The barring gear is hydraulic and could be used to bring it up to a very low speed, perhaps the VFD is able to bring the frequency down to that speed to allow the...
Some vendors now offer a variable speed drive to use for acceleration and turning gear for Gas Turbines instead of starter motors.. Since synchronous motors are not inherently self starting, use an embedded squirrel cage, does any one have an explanation how this is applied to use the generator...
