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’s designed for earth injection testing, which involves injecting current into an earthing system and measuring the response to assess grid integrity and simulate fault conditions for protection testing.
Yes. The unit can simulate earth fault conditions, making it suitable for testing earth fault relays, residual current relays, and verifying pickup thresholds.
It can inject up to 25 A, depending on output voltage and site load impedance. It’s designed for low-impedance, high-current injection typical of substation grounding systems.
• The 4023 is the control unit, allowing voltage adjustment, metering, and overload protection
• The 4024B is the injection transformer, stepping down the voltage to provide high current output
Yes. Both units are compact, ruggedised, and supplied in a transportable configuration suitable for field deployment in substations and switchyards.
• Substation earth grid continuity and impedance checks
• Verification of fault current paths
• Relay pickup point testing
• Current distribution across earth electrodes or structures
• 4023 control unit and 4024B injection transformer
• Power and interconnect cables
• Heavy-duty output leads and clamps
• Operation manual and transport case
Yes. We offer remote support and test connection guidance, particularly helpful for earth injection setups which vary by site.
