Objectives "Using an impedance earthing inversion trailer unit, the following are proposed:* an assessment of impedance earthing and a comparison with solid earthing (in the form of a written report)* the discussion of protection implications (modelling determining reliability, stability, and safety)* recommendations for other safety measures (insulated or conductive matting, building on some recent experiences with SPEN and others in this regard).* Trial of an inversion trailer unit and tests will be conducted at a facility where a variety of faults (or line energisations) can be applied to the system. The resulting EPR (earth potential rise), protection operation times, and safety voltages can be measured to ensure practice aligns with theoretical/modelled values and to give confidence in the reliable operation of the system. " "The project includes theoretical modelling, which will be undertaken to explore the viability of the proposed approach.Equipment development will utuilise UKPNs inversion trailer for prototype development and testing at PNDC.Comparison of the equipment testing results against theoretical models will be undertaken leading to the production of a high-level specification and report detailing list of recommendations with a view to post-project field implementation. " "Key objectives are as follows:*Complete desktop research on worldwide operations of unearthed or ASC/Petersen coil earthed systems*Create model 11kV system to represent typical overhead line networks and complete system studies.*Determine parameters for testing and test plan.*Testing of Inverter/Transformer and Protection Configuration*Analysis of Results & Comparison against Theoretical models*Develop technical specification for the inversion transformer unit*Produce report consisting of the earthing methodology, focusing on practicalities of impedance earthing, and a comparison with solid (low impedance) earthing. "
