UL works on safety standard for Canadian electric utility meters


UL-Canada-electrical-meter-safety-standardGlobal standardization and safety company Underwriters Laboratories announced yesterday that it is developing an electric utility meter standard for Canada in a bid to address safety concerns in the wake of smart meter failures in the country.

UL said in a statement that it will work with Canadian stakeholders to develop a new standard to cover the electrical safety of meters.

The team working on the project will base the new standard on a current protocol for electric utility meters – UL 2735 – in order to speed up the process.

UL 2735 is already used in both Canada and the US for testing and verification.

Robert A. Williams, vice president of standards at UL, said: “The ability to use the existing UL standard as a base document will assist a more efficient and cost-effective process in meeting those needs.”

Call for participation

UL has put out a call for participation from interested stakeholders across Canada.

UL is actively involved in international standardization with both ISO and IEC and facilitates the participation of US and Canadian stakeholders on international technical committees.

Canadian smart meter fires

The news comes as the tally of smart meter failures in the Canadian province of Saskatchewan climbs to nine.

An investigation into the cause of the fires at the homes of state utility Saskpower’s customers revealed that “shortcomings” in the design of the Sensus Generation 3.3 meters triggered them to overheat.

SaskPower is currently developing a new smart meter module with US manufacturer Sensus.

It is unclear at this stage whether the new meters will have to wait until the new safety standard has been approved.
