RALEIGH, N.C. – Sensus is conducting utility site inspections and performing extensive lab testing to determine the root cause of recent smart meter incidents.
The results to-date from the clean technology company point to contributing external factors that caused the incidents such as water intrusion due to holes in meter boxes, hot socket conditions in the meter box and over voltage in the distribution system.
“I have been personally involved with our customers and Sensus quality and engineering teams as we work to collect fact-based and data-driven information on these specific incidents,” said Sensus President Randy Bays.
Product design engineers and quality teams are working closely with customers to understand the specific events that led to recent issues that impacted a number of iCON A Generation 3 2S remote disconnect meters, Sensus said.
Data received from seven recent issues in an installed base of 175,000 meters points to contributing, long-standing industry issues; one was caused by an issue with a meter base attached to a home, three were caused by utility over voltage, two were caused by water intrusion through the meter base, and one remains under investigation.
Sensus underscored the critical importance of careful meter installation procedures, including the examination of meter boxes and wiring at installation, training of meter installers and the need to have rapid remedial action when field problems are observed.
All manufactured meters are subject to ANSI standards including: ANSI C12.1-2008, Code for Electricity Metering and ANSI C12.20-2010, American National Standard for Electricity Meters 0.2 and 0.5 Accuracy Classes.
Given that there are more than 40 million meters deployed to date in North America, the failure rates seen in the industry are very low, according to the company.
Sensus remains focused on working with utilities to help them understand and address external issues that impact meter deployments.
