SUMMARY

The discussion centers on Peter Hammond's contributions to the development of medium-voltage drives, highlighting innovations from the 1990s. Key advancements include the use of fiber optics for isolating control signals and the implementation of a cellular setup where each cell generates its own control power. Participants emphasize the importance of balancing systems, such as voltage dividers, to prevent cells from floating apart. This conversation showcases the blend of creativity and engineering principles in medium-voltage system design.

What is innovation ? ... here is a great example.

I'm in this field and know this product pretty well. I though it may be interesting to both the old and new PF members...

Very nice, thanks @Windadct -- nice touch on using fiberoptics for isolating the control signals. :smile:

Aha moments (or weekends) are one of the best parts of Engineering, IMO. :biggrin:
 
In in this MV cellular set up - each cell effectively has it's own ground, and has to generate it's own control power, lots of small innovations - and to think this was not that long ago (90's). Every cell's superstructure has to be isolated from the next, but then also you need balancing system - like a voltage divider, so that no one cell "floats" too far away from the others. Isolation of structures in MV systems is "fun".. haha
