Provide specialist technical review of new HV infrastructure, including incoming 66kV switch rooms, transformer sizing, busbar protection and substation layouts, identifying potential design deficiencies before construction. Provide SME support across HV testing, commissioning, maintenance, capital projects and fault/emergency response. Work across state and federal regulatory requirements to ensure a consistent and robust HV operating framework across NEXTDC's national portfolio.
  • ● + years' experience working with HV electrical systems within a mission-critical, utility, power generation, large industrial or hyperscale data centre environment.

Experience with protection coordination studies and relay settings management. Experience engaging with utilities, network operators and regulators on HV connection, protection and network interface requirements. The ability to lead or provide technical direction across HV testing, commissioning, maintenance and fault response.
