Australia has vast expanses of outback terrain and scattered, remote mining areas, which are often served by single-phase overhead power lines stretching for tens of kilometers. As the transmission distance increases, line impedance leads to significant voltage drops, creating an urgent need among customers to address the problem of the voltage at the grid’s endpoints falling well below the requirements of the Australian standard AS/NZS 60038.

Core Pain Point:

Large voltage fluctuations occur because voltage levels are barely acceptable during the day when loads are light, but they drop sharply to between 160V and 180V at night.

Solution:

A customized single-phase step voltage regulator has been developed to suit the specific characteristics of the Australian power grid. Unlike ordinary automatic voltage regulators (AVRs), this device employs “stepped voltage regulation” technology, which achieves distortion-free voltage compensation by controlling a multi-tap autotransformer.

Strong Power’s single-phase stepped voltage regulator offers an efficient, economical, and reliable solution to the voltage drop problems commonly experienced in remote areas.
