Why Hire HV Test Equipment from Megavar?

Unlike general equipment rental companies, Megavar is a specialist high voltage engineering firm. Our commissioning engineers use the test equipment we hire out every day on live substations, BESS installations, wind farms, and solar plants across Australia.

When you hire from Megavar, you get more than a piece of equipment in a case. Whether you need an Omicron CMC 356 for protection relay testing, a CPC 100 for primary injection, or a Megger insulation tester for transformer diagnostics, it is in our fleet.

No lock-in hire periods. Flexible delivery and pickup. Fault support when you need it. That is what sets Megavar apart from the rest.

Why Megavar

Our Approach

Practising Engineers, Not a Rental Desk

Megavar’s commissioning engineers use our test equipment every day on live substations across Australia. When you work with us, you get engineers who operate the gear, not staff reading from a manual. When you hire from our fleet, you get the instruments they run on site.

End-to-End HV Services

From substation design and protection engineering through to commissioning, maintenance, and HV test equipment hire, Megavar delivers the full project lifecycle. Our integrated service model reduces handovers, minimises delays, and gives you a single point of accountability from design through to energisation.

National Coverage, Local Knowledge

With offices in Hobart, Launceston, Adelaide, Newcastle and Gladstone, Megavar delivers fast response across every state and territory. We commission substations on networks from TasNetworks to ElectraNet to Ausgrid, so we understand regional standards, utility requirements, and local conditions.

ISO Accredited and Licensed Nationally

Megavar holds ISO 9001, ISO 14001, and ISO 45001 accreditation and electrical contractors licences in every Australian state. When asset owners and head contractors require qualified, accredited service providers, Megavar meets the standard every time.
