APD Engineering conducted detailed earthing studies as per AS/NZS 4853:2012 including; EPR, LFI and EMF hazard assessments as well as review of proposed cathodic protection and other gas pipeline ancillary services (below and above ground). Site testing works were also undertaken to validate the detailed CDEGS modelling results.
APD Engineering was engaged to undertake Insulation Coordination and Reactor Switching Studies for a 275kV substation in South Australia. Advanced studies based on PSCAD/EMTDC modelling were carried out to ensure the safe operation of the substation through surge protective devices.
Secondary scope to facilitate reconfiguration of 66kV transmission lines connecting to the Alinta Power Station on the BHP network, including Line protection relay upgrades.
Power line modelling and Design for the 66kv reconfiguration outside of Yarnima Substation.
APD’s Power System Studies team provided First Quantum Minerals (FQM) with end-to-end services from detailed site survey (data collection), to computer modelling and system analyses. With a model of the mine network, FQM can investigate various contingency events & plan for the most cost-effective network utilization.
