Megavar engineers use this unit on commissioning projects across Australia. Hire it from a team that knows it inside out.
All Megavar test equipment is maintained under a documented calibration programme. Instruments are calibrated either by external calibration laboratories or in-house against reference standards that are themselves laboratory-calibrated, with measurement traceable to Australian national measurement standards held by the National Measurement Institute. A current calibration certificate is available on request. If your project requires a specific calibration interval, test standard, or documentation for a client submission, tell us at enquiry on 1300 730 499 and we will confirm what applies before you commit.

It is used for high-voltage AC withstand testing on long-length cables, GIS, and transformer windings. It validates insulation performance under stress conditions as per international standards.
Resonant systems require far less input power to reach high voltages because they rely on resonance between inductive and capacitive elements. This makes them compact and efficient, ideal for testing very long or high-capacitance loads.
It complies with IEC 62067, IEC 60840, IEC 60060-3, and IEEE 400.4, depending on configuration and application.
Typical systems can output 100–600 kV AC RMS continuously, with test durations of up to 60 minutes. Duration and voltage depend on the application and the system configuration.
• Extra-high-voltage cable systems (HV and EHV)
• GIS switchgear assemblies
• Large power transformers
• Shunt reactors, cable terminations, and insulators
Yes. Resonant test sets are often skid-mounted or containerised and configured for transport to substations, wind farms, or industrial test yards.
Yes. You can connect MPD 600 systems to monitor PD during the withstand test.
• HV resonant test system: control unit, excitation transformer, reactor(s), HV divider
• Interconnect cables and earthing system
• Technical drawings and connection guide
• (Optional) MPD 600 for delta testing
• Setup support and on-request commissioning assistance
Yes, due to the specialist knowledge required, this set will only be wet hired along with Megavar’s testing resources to operate it.
Typically 3–5 days, depending on mobilisation and demobilisation requirements. Weekly and monthly hire rates are available.
Submit your rental request online, and our team will respond promptly with availability, pricing, and expert advice.
Once confirmed, we’ll quickly process your booking and dispatch the equipment. Delivery and collection can be arranged to suit your schedule.
