Autorecloser and integrated power supply
Autorecloser and integrated power supply
(OP)
Please I want to design an integrated power supply for an autorecloser. This power supply will be a part of the recloser itself which means that the use of external distribution power transformer to supply auxiliary power to the recloser will be eliminated but the problem is that I don't know how to extract energy from the medium voltage line without the use of transformer. Please, I will be very glad if somebody can suggest to me how I can get out energy from the MV line without the use of transformer. Please, any technology that can solve this problem will be highly appreciated.






RE: Autorecloser and integrated power supply
If that's not an option, how about a UPS? You could run the recloser off of a distribution transformer, through the UPS. When the power is cut, the UPS will provide power for some amount of time depending on size and power requirements.
Or perhaps I do not understand the question...

If it is broken, fix it. If it isn't broken, I'll soon fix that.

RE: Autorecloser and integrated power supply
Thanks for the response so far. I am working on 15kV distribution line. The recloser is expected to get its primary auxiliary voltage from the distribution line without the use of a transformer. Therefore, I am actually looking at how I can get 120V usable voltage from the distribution line without the use of transformer. Please, is there any technology or small device that can help me achieve this aim? Thanks for your assistance.
