We need a 80 kVA transformer which can create an Y-net with starpoint by using a threephase triangle circuit. At the output there will be very high unbalanced loads connected on one phase.
The transformer should have a switch so it can be turned on or off and it hast to be fused against overload. As the device will be placed in an outdoor area it must have protection class IP 54. Hum noise must be as low as possible. The transformer will be delivered to USA Las Vegas, thus the input voltage has to be 3 x 208 V ad additionally all used materials must be UL certified.
