PreSenTeDBy BehroUzGhorBanIan BSC,MSC,MIeaUST Behrouz completed his degrees in Telecommunications andelectrical engineering in 1985 and 1993 respectively, and thenconcluded his studies in electrical Utility engineering at CurtinUniversity(Perth)in2004.Behrouzstartedhiscareerintheoilandgas industrywherehis rolegothim involved in themaintenanceand repairofelectronicandnavigationalmarineequipment (VhFandSSBradios,Satnav,enginecontrolpanelsetc).hethenmovedtothepowerindustryandwasinvolvedinthedesign,installation,andcommissioningofsubstationsmainlyforconsultanciesandutilities.hehasalsoestablishedagoodreputationinteachingpowersystemprotectionoverhislongtermserviceslecturingatCurtinUniversity,andalsoovertheperiodheworkedasaProtectionengineerinnewzealand.

overthepastyears,Behrouzhasbeeninvolvedinmanymajorprojectsacrossaustralia(Porthedland,Barrow Island, Tamar Valley, Karratha, and newman for example). his most recent experience isrelatedtocostestimationandriskassessmentofmajorsubstationprojectswithaspecialfocusonthesecondarysystems(Protection,CoMMS,SCaDa).hehasalsoworkedasanengineeringManagerandSenior Project engineer on major copper mine projects overseas. Behrouz has also gained goodknowledge in substation design, hV cables sizing and installation, transmission system design,earthingsystemdesignandapplications,andpowersystemprotectiondesignandapplications.
