Comprehensive High Voltage Capabilities When You Need

When your business relies on critical electrical assets, you need a partner who understands the complexity of these systems, power authorities, local regulations and the environments in which they operate. Our engineers and technicians are here to help with high-voltage services, covering system audits, earthing studies and designs, protection studies and arc flash studies, high voltage equipment upgrades, HV switching programs, substation works and HV protection upgrades, transformer testing and installation, and a deep understanding of HV substation design in Melbourne. All of this completed in house at ARA Electrical Services.

We apply structured, registered, engineering processes to reduce risk and enhance network resilience, ensuring that your assets operate reliably over the long term. This includes modelling system behaviour, reviewing fault ratings, analysing incidents, and developing improvement strategies that align with both site requirements and industry best practice, an approach strengthened by collaboration with high voltage network design consultants in Melbourne when applicable.

Engineering & System Design that Works

Many facility challenges begin at the design stage, which is why our engineering team plays such a central role in every project as we integrate lessons from broader high voltage network design in Melbourne. We develop detailed plans for cable routes, reticulation, switching procedures, protection coordination, and distribution layouts. Our experience allows us to manage complex projects involving brownfield upgrades, expansions, and connections to utility networks.

This engineering-driven approach ensures continuity between the conceptual design, construction, commissioning, and long-term maintenance, allowing your site to benefit from high-voltage assets that are robust, maintainable, and efficient.

We are also here to support clients who require detailed technical documentation for compliance, electrical authority approvals, or internal safety management systems drawing on established principles used in high voltage engineering design in Melbourne. Our goal is simple: To make the process straightforward while upholding the highest standards of reliability and accuracy.

Get Installation, Upgrades & Commissioning Expertise

High voltage equipment must be installed and commissioned with absolute accuracy. Our field team is trained and authorised to work within the stringent safety and compliance frameworks that govern high-voltage environments. We follow proven standards recognised for high voltage engineering in Melbourne.

We provide installation of HV switchgear, cables, transformers, earthing systems, and auxiliary components. During upgrades and expansions, we will see that your equipment integrates seamlessly with existing assets, minimising disruption to your operations.

Commissioning activities follow structured tests and verifications to help your system perform exactly as designed, covering functional testing, relay configuration checks, interlock validation, HV switching programs, and energisation support.

Asset Maintenance & Lifecycle Support

High voltage assets require ongoing maintenance to prevent failures, reduce operational risk, and prolong equipment lifespan. Our maintenance programs are tailored to each client’s facility, considering asset age, manufacturer recommendations, operational load, and environmental conditions.

We offer scheduled inspections, thermographic analysis, cable testing, partial discharge assessments, transformer oil sampling, and protection relay testing. For facilities with critical operations, we also provide rapid response for unexpected outages, fault investigations, and breakdown recovery.

With long-term asset planning, you will understand when upgrades are required, how to manage an ageing infrastructure, and plan operational budgets accordingly.

We Can Help with Safety, Compliance & Risk Mitigation

Safety underpins every high-voltage project and we understand it for the better. Our methodologies are compliant with Australian standards, electrical authority requirements, and site-specific rules. We assist clients in strengthening their high-voltage safety frameworks by providing documentation such as switching plans, risk assessments, isolation procedures, and hazard controls.

Our commitment to safety extends to project execution, where our teams follow strict protocols to manage electrical risk, mechanical hazards, confined spaces, and environmental factors.

Integrated Project Management is at the Heart of Our Process

Complex HV projects require careful coordination across engineering, procurement, construction, commissioning, and handover. Our project managers oversee the full process to ensure that timelines are met, stakeholders are briefed, and every stage complies with design intent and industry standards.

We work collaboratively with consultants, utility partners, facility managers, builders, and maintenance teams to deliver a seamless project outcome.
