Twin lakes are located in Manjimup Western Australia; three phase power from the power utility was out of the question to run the three phase cool rooms to chill the broccoli at this rural location, an R/75/480b POLYPHAZ converter was specified to operate these loads via 2 x 50KVA single phase transformers.

The results taken 11/11/2005

Input single phase volts no load: 492volt
Underload      467volts amps: 90.7
Output three phase volts under load:  L1>L2: 419
L2>L3: 416
L1>L3: 407  (low due to supply volt drop)
Output three phase amps  under load:  L1: 70.3
L2: 73.7
L3: 61.5
