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.
