Power Systems Partners Ltd – Stand QE11

Power System Partners Limited is a Company representing a range of Original Equipment Manufacturers (OEMs) associated with the electrical supply industry. Originally formed in 2006, with the support of SGB Smit Transformers, Power System Partners grew the market for SGB Smit’s range of grid and super gird transformers along with SGB’s range of cast resin and distribution transformers. 

Always keen to add complementary equipment to the transformer ranges being offered, Power System Partners quickly added Coleme, a HV and EHV disconnector manufacturer, to the portfolio along with Tamco Switchgear, who provide 11kV and 33kV switchgear. 

The company has also expanded into offering complementary products based around cast resin and distribution transformers. This includes busbar solutions, surge arresters and protection devices. 

Power System Partners recently added representation for a novel permanent magnet fault current limiting device which can instantly reduce fault levels on the 11kV network. This enables connections onto the 11kV system where fault levels have previously been a limiting factor, helping the network to adapt to changes resulting from more distributed generation.
