Innovative research at Strathclyde University, embodied in its spin out Diagnostic Monitoring Systems (DMS) Ltd, has enabled the Glasgow-based company to become the premier supplier of ultra-high frequency (UHF) systems for detecting harmful partial discharge (PD) activity in high-value gas insulated substations and power transformers. Annual sales rose from £6.7M in 2008 to £11M in 2012, and its staff doubled to 56 employees. DMS’ equipment is utilised in 27 countries, with total exports over 2008 – 2013 exceeding £45M. A sustained partnership with Strathclyde has yielded new sensor technologies and secured mainstream international recognition for UHF PD detection techniques, which are being incorporated within a new IEC standard. Economic value of Strathclyde’s UHF technology was further emphasised in 2009 when DMS was acquired by Qualitrol, part of the US $46B Danaher Corp that owns numerous global engineering brands including Tektronix, Fluke, Leica Microsystems and Gilbarco Veeder-Root.
