AUSGRID CT METERING

Large commercial and industrial supplies on the Ausgrid network use CT (current transformer) metering rather than direct-connected meters, because the load exceeds what a standard meter can measure. Sydney Power Group installs and connects CT metering across the Ausgrid supply area for commercial premises, strata and industrial sites.

When CT Metering Is Required

Once a supply exceeds the current rating of a direct-connected meter (typically large commercial, industrial or multi-unit loads), Ausgrid requires CT metering. Current transformers step the current down to a level the meter can safely read. This is common for warehouses, large strata blocks and commercial fit-outs across the Ausgrid network. See our metering service.

Installing the CT Chamber

CT metering requires a compliant CT chamber and correctly rated transformers wired to Ausgrid standards, alongside a three-phase supply. We design, install and connect the metering to suit your load, coordinating the switchboard and network sides for a large commercial connection.

For Builders & Businesses

Fitting out a commercial premises or building a multi-unit development on the Ausgrid network? We manage the CT metering as part of the connection so your energisation is not held up. We also coordinate with your electrical contractor and retailer.

Talk to a Level 2 ASP

CT metering connects to the Ausgrid network and must be handled by an authorised Level 2 ASP. We are accredited for commercial metering and lodge all compliance. Call 0466 125 125 or use the contact page.
