The Tony Davies High Voltage Laboratory Laboratory Overview The Laboratory has been active on its present site since being constructed in 1991 with funding from STC Submarine Cable Systems. While primarily the Laboratory is a research facility, commercial testing and consultancy are undertaken on a regular basis. Personnel: • 7 academic staff • 5 full-time research staff • 25 full-time postgraduate students • 3 laboratory technical staff Expertise in the laboratory covers the full spectrum of high voltage engineering, from dielectric materials science to condition monitoring and testing of high voltage plant. Research Areas • Condition Monitoring of HV Plant, particularly cables/transformers • Environmental Modelling using techniques such as FEA and CFD • HTS Power Apparatus, notably cable terminations/generators • Liquid Dielectrics, including both conventional and novel oils • Plasma & Space Technology, focusing on electric propulsion • Solid Dielectrics, especially complex polymeric systems • Space & Surface Charge, as applied to HV cable and GIS systems Facilities & Testing Capabilities The Laboratory has a wide range of HV facilities which we use for both research and commercial testing to a range of BS and IEC standards: HV Facilities • Up to 1MV/50kJ impulse generator • Up to 300kV AC - pd free to less than 1 pC • Up to 600kV DC • Environmental chamber for fog, salt fog and rain tests on live components • Screened room for low noise measurements • Partial Discharge testing to IEC 60 270 Materials Analysis • Characterisation using UV/Vis and IR spectroscopy, Differential Scanning Calorimetry (DSC) and Raman microscopy • X-ray analysis • Dielectric spectroscopy - Capacitance and Tan Delta measurements Numerical Modelling • A range of finite element/CFD tools, plus the development of bespoke codes www.highvoltage.soton.ac.uk Contact: Neil Palmer Faculty of Physical and Applied Science [email protected] + 44 (0) 23 80 59 32 38
