Automated dairy farm, Mt Gambier South Australia powered by POLYPHAZ single to three phase rotary converter.
Mt Gambier dairy farm South Australia
This Automated dairy runs 24/7 and as such reliability , easy site fault diagnosis , and low power consumption , Vermin proof were all on the top of the list for this type of application.
Installed at Mt Gambier South Australia, this had a high specification with regards to three phase and single phase power output voltage , power consumption / losses, and short circuit fault rating.
"The Polyphaz unit is running very quiet and is much quieter than the small 2.2kW Vacuum pumps that are in the same room as the Polyphaz unit. The Dairy Farmer is very impressed with the unit." 15/9/2011
Site test results taken by 15/9/2011 , model: R37/480C:
POLYPHAZ converter output three phase voltage: L1 > L2= 418v, L1 > L3= 429v, L2 > L3= 426v.
POLYPHAZ converter output single phase voltage: L1 > N = 237v, L2 > N = 244v, L3 > N = 243v.

Load snapshot
Input power consumption: L1: 26amps , L2: 25amps @ 479volts
Input 1 phase watts: W= V x A x P.F = 479 x 25.5 x .99 = Watts: 12092.35
Output power consumption: L1: 13amps, L2: 18amps, L3: 16amps , averaged: 15.7amps
Output 3 phase watts: W= V x A x P.F x 1.732 = 424 x 15.7 x .99 x 1.732 = Watts: 11414.28
12092.35 - 11414.28 = 678 watts
Results :
3 phase voltage asymmetry: 2%
1 phase voltage asymmetry: 2%
loaded converter losses: 678watts
Efficiency loaded: 95%
unloaded converter consumption: 455 watts
Short circuit fault rating: 25 KA
Power factor .99
C-tick approved yes
These results are impressive, particularly the low power consumption from a 37KW or 50HP capacity rotary converter capable of 6 x F.L.C multi motor starting, the end user gets the benifits of a rotary converter without the downside of power consumption, this is achieved by using our unique floating pole rotary's and maintaining the Power Factor at unity throughout the load spectrum while maintaining a relitively high fault rating of 25 KA.
A high short circuit fault rating is important and often overlooked particular in larger installations like this, for example if a fault accures downstream of the converter and the converter is supplied by say a 100 KVA transformer with a high fault level
a low fault rated converter serves as a expence fuse in the event of a short circuit fault.
