Regulation of the mains voltage down in 3 phase system
Regulation of the mains voltage down in 3 phase system
(OP)
Hello,
I am solving now a problem how to regulate down mains phase voltage in 3 phase system from 230VAC to 170 VAC. My first idea was to use transformer with one part with fixed ratio + in secondary connection of various secondaries in series. The problem is the huge variation of currents in secondary ( 170 VAC may be requiered at few tens of Amp and also few hundreds of Amp as well at the secondary ).
For this reason I have found some alternatives:
1.) Synchronous generator
2.) Induction regulator
Are some other alternatives to solve this issue except 2 mentioned above ?
Any advice will be appreciated.
Gabriel.

If you tell us the application we can help with the solution. What is your load?
What are your regulation limits?

This output voltage range should be avaiable for currents from 60A to 600 A / phase, now the particullary important area for me is 170V-180V area.
The aim of this system/device would be test system performances at the worst case low mains for various machines.
