Megavar engineers use this unit on commissioning projects across Australia. Hire it from a team that knows it inside out.
It is used to verify low-resistance bonding between earth grid components, ensuring effective fault current paths and compliance with substation earthing standards.
The tester outputs up to 100 A DC to accurately measure the continuity of large conductors or welded joints that require high-current verification.
Yes. It is specifically designed for substation environments and is widely used by utilities, HV contractors, and commissioning engineers.
• Welded and mechanical joint continuity
• Transformer bonding verification
• Switchyard and gantry bonding tests
• Cable tray and earth grid connection checks
Testing is initiated manually with a start switch. Visual (LED) and audible indicators signal test progress and result (pass/fail).
No. The 4022C is a go/no-go continuity tester. For actual resistance measurements, a micro-ohmmeter (like the DLRO series) should be used.
• 4022C main unit
• Output cables and heavy-duty clamps
• Power lead and user guide
• Rugged transport case
Yes. We offer remote technical support and connection guidance, especially useful when testing multiple or complex bonding points.
