CRE, responsible for design of Network Rail Substation upgrades at various sites including TPH to substation conversions, DC Switchgear renewal, HV Switchgear renewal and Transformer Rectifier renewal.

Responsible for safety assurance documentation and independent design check for the Jubilee Line Earth Distribution Network, Jubilee Line traction power upgrade and the Northern Line traction power upgrade.Investigate rate of ageing of track feed cables subject to temporary overload, to determine risk of increased loads on existing cables.Interpretation of Multi train simulator results to determine the need for conductor rail upgrade in the context of London Underground standards. Assess the impact of modelling deviations from the reality on the validity of the results to propose an economic and efficient solution.

Power system study for ALSTOM Australia for the new Parramatta Rail Link in Sydney. Computer simulation of the high voltage AC, traction DC and catenary current collection system. Calculation of train performance, overhead wire voltage and current, rail to earth voltage, 33 kV loads as well as traction rectifier loading. Electromagnetic compatibility (EMC) study for Network Rail. Determine the longitudinal and transverse voltages under 33kV AC load and fault conditions that may arise when signalling and telecommunication cables are positioned adjacent to 33 kV traction distribution cables. Assess the performance of direct acting overload (DAOL) and impedance protection on a specific section of the London Underground (LU). Power system study for COBRA Instalaciones y Servicios on the Delhi Metro Corridor (25 kV). System analysis with a multi-train simulator to determine the equipment loading, and calculation of stray currents and induced voltages. Develop recommendations for bonding and earthingCalculate touch voltages induced in telecommunications cable for various scenarios of ballast resistance, earth resistivity, booster arrangements, and screening arrangements. This investigation was done for a new electrification between Rawang and Ipoh in Malaysia.
