CASE STUDIES   Single to Three phase   POLYPHAZ Rotary converters

Toolibin  Lake converter   Dept. of conservation & land management
 

Lake Toolibin is located approx. 250 Km from Perth Western Australia , three phase power was required to operate 2 x 7.5kw compressors , 1 x 7.5kw pump operated by a Danfoss VSD , however three phase power was many Kms away & very expensive to get connected.
A rotary converter was selected as the most cost effective solution . The converter operates continuously with compressors cycling  off /on load to supply compressed air to the AIRWELL pumps , both pumps supply the tank with salt water  which  in turn is pumped out of the tank via the 1 x 7.5kw pump.
The VOLTRAK option was required as a good voltage asymmetry was necessary to operate the VSD & to get the required performance from the air compressors at this location.

Three phase power was a expensive option to operate the air-conditioning units for the three villas at this winery, a R/37/480hd unit was used to operate all the units via 2 x 25kva transformers, as all the A/C units have power supply monitoring as standard so the VOLTRAK power monitoring was required.
