Australian Square Kilometre Array Pathfinder (ASKAP) Telescope

In 2016, Tortech was proud to be selected as the supplier of the 3 dry type three phase transformers of the rating 1.6MVA, 1.5MVA and 250kVA to the CSIRO due to it’s previous reputation in delivering quality transformers that require specialised knowledge to design.

This project for CSIRO is the Australian Square Kilometre Array Pathfinder (ASKAP). This telescope is regarded as the world’s fastest survey radio due to the 36 ‘dish’ antennas placed together within a 6km radius. Their design is to function as one instrument called an interferometer which provides a wider field of view of surveillance for the satellite.

Tortech did face difficult challenges where our design engineers had to take into account the harsh, rural environments with high temperatures in the Western Australia deserts. Due to Tortech’s in-house simulation programs and experienced engineers, we were able to develop and test transformer models to meet the strict standards set by CSIRO to win the contract. As photographed below, our 1.6MVA transformer can be seen open with and without the enclosure.

This Tortech transformer was designed to be used with specialised Inverters which are supplied by Solar Powered batteries. The Transformer is used to convert the voltage to 6.6kVA to the mini-grid established for the ASKAP base array.

The most remarkable achievement of the design was the transformers’ ability to meet the very low electromagnetic interference requirements of the grid. Tortech is proud of it’s ability to design, manufacture and deliver such a high quality transformer for such an important facility in Australia.
