The Powerstar SO-LO® range of super low loss transformers are the only amorphous core transformers designed and manufactured in the UK and provide a cost-effective way of reducing your energy consumption by upgrading your HV infrastructure.

Replacing your transformer with a low loss amorphous core could reduce core losses by up to 75% when compared to traditional CRGO transformers.

Why amorphous?

The traditional distribution transformer was made of carbon steel. This evolved to silicon steel and eventually to the cold rolled grain-oriented silicon steel (CRGO) laminations that make up the average present day traditional transformer.

Due to increased levels of interest in producing more sustainable and environmentally friendly equipment in line with the global movement of carbon reduction, materials that exhibit the qualities of low core loss and low magnetostriction, such as amorphous alloy, have become a particular point of interest.

Findings show that amorphous core transformers provide a super low core loss alternative to conventional transformers whilst providing higher efficiencies, longevity, and low magnetising current.

Enhancing savings with voltage management

Further efficiencies can also be made by combining a super low loss amorphous core transformer with voltage management technology.

By combining SO-LO with electronic-dynamic voltage management both the inefficiencies in the HV infrastructure can be improved whilst also generating additional savings through reductions in energy consumption and CO2 emissions from the LV side through patented voltage optimisation technology.

These benefits combine to maximise your return on investment, minimise your payback period, and provide a complete HV/LV solution. Find out more by clicking here.

A smart approach to low loss transformers

Transformers are critical infrastructure for many companies, yet they are not connected and online. Therefore, their health, performance, and efficiency are typically unknown or reliant upon manual inspections of antiquated gauges/meters.

Powerstar SO-LO remote monitoring allows 24/7 visibility to help you better understand how your transformers are performing and where efficiencies can be made to obtain the best return on investment.

Developed with Industry 4.0 in mind, which is defined by Mckinsey and Company as the next phase in the digitalisation of the manufacturing sector, Powerstar SO-LO remote monitoring provides comprehensive data and intelligence to provide useful grid information, conditional performance data, and energy efficiency reports. It has been designed to complement maintenance activities and allows for the remote monitoring of core temperatures, winding currents, oil temperature and, when integrated, the performance of voltage management functionality.
