Chartered Electrical Engineers in Melbourne
ARA Electrical Services provides chartered electrical engineering for industrial and commercial projects across Melbourne, Victoria, and key industrial sites nationally. Our chartered engineers hold accreditation through Engineers Australia, with practice experience across power system design, HV infrastructure, protection engineering, earthing system design, process automation, and hazardous area electrical engineering.
ARA’s chartered engineers are engaged on projects where technical decisions carry significant consequences for system performance, safety, and regulatory compliance — high-voltage infrastructure, protection relay scheme design and verification, power system studies, grid interface works, and major industrial installations where the engineering is required to meet a standard that withstands client review, regulatory scrutiny, and long-term operational reference.
Power System Studies and Protection Engineering
ARA’s chartered engineers carry out power system studies covering fault level analysis using IEC 60909 methodology, load flow assessments, protection coordination and discrimination studies, short-circuit withstand verification, and voltage regulation analysis for LV and HV distribution systems. Protection relay scheme design includes relay characteristic selection, time multiplier and definite time setting calculations, instantaneous element coordination, and inter-trip and transfer trip scheme design for HV substation and feeder protection applications.
Study outputs include written reports, time-current characteristic plots, relay settings schedules, and recommendations for device selection or setting changes to achieve the required coordination margins. These outputs are structured for use by client engineering teams and form part of the project commissioning and asset management documentation.
Hazardous Area Engineering
ARA’s chartered engineers provide hazardous area electrical engineering across chemical, petrochemical, oil and gas, pharmaceutical, and food and beverage facilities. This covers hazardous area classification to AS/NZS 60079.10.1 and AS/NZS 60079.10.2, electrical design and equipment selection for Zone 0, 1, 2, 20, 21, and 22 classified areas, and preparation of area classification drawings and documentation to AS/NZS 60079 series requirements.
Chartered engineering input on hazardous area projects covers Ex equipment selection and certification review, installation design to AS/NZS 60079.14, inspection and maintenance scheme development to AS/NZS 60079.17, and technical support for hazardous area management plans. For complex or high-consequence hazardous area installations, chartered-level review provides the engineering accountability and documented technical basis that clients and regulators require.
HV System Design and Grid Interface Engineering
ARA provides chartered engineering support for HV switchgear specification, substation and transformer design, protection relay scheme development for HV feeders and transformers, and technical coordination with distribution network service providers on connection, metering, and protection interface requirements. Grid-connected projects are engineered to satisfy both client technical standards and DNSP connection conditions, including power quality assessment, protection relay settings submissions, and metering scheme design. For embedded generation and renewable energy connection projects, ARA provides protection scheme design covering loss of mains detection, islanding prevention, rate of change of frequency and vector shift relay settings, and coordination with upstream network protection to satisfy DNSP technical requirements for generation connection.
Earthing System Design and Analysis
ARA provides earthing system design for LV and HV installations, including substation earthing design to AS 2067, touch and step voltage analysis, soil resistivity assessment and electrode configuration, mesh and rod earthing grid design, bonding strategy for industrial facilities, and earthing system performance verification. For HV substation earthing, fault current distribution analysis is carried out to determine earth potential rise and confirm that touch and step voltages remain within the limits specified in AS 2067 under maximum fault current conditions.
Technical Documentation and Design Review
ARA electrical prepares and reviews engineering documentation to the standard required for construction, commissioning, regulatory submission, and long-term asset management. This includes single-line diagrams, protection relay settings schedules, earthing design reports, power system study reports, technical specifications, and functional design specifications for control and automation systems. For projects requiring independent design verification, ARA provides formal design review against the relevant Australian Standards and project technical requirements.
Multi-Discipline Engineering Capability
Many of the projects ARA works on require engineering input across power systems, protection, automation, machine safety, and hazardous area design. ARA’s in-house capability across these disciplines, developed and reviewed under chartered-level oversight, means the engineering on complex industrial projects is developed with a clear understanding of how each system interfaces with and affects the others.
