Over the weekend, I was asked if I was interested in getting involved in setting up a network that would operate as follows:
- Primary Voltage 10kV / Secondary Voltage 400V.
- 4 substations each approximately 250metres apart.
(four corners of a square).
- Network primary AND secondary selective...
I have been asked to size a generator to start two 75HP motors at star-delta(wye-delta), starting on-load and at the same time.
The machine is a wood-shredder so I assume that there is a high starting torque requirement.
It seems to me though that a star delta start (with open transition)...
