Temperature rise standards tests differences and performance assessment for electricity meter and meter socket interface

A committed group of utilities, equipment vendors, and other stakeholders working under the auspices of ANSI with the “TRINIWOG” (Temperature Rise and Interface Issues Working Group) name have been investigating temperature rise issues related to the electricity meter/meter socket interface. These issues appear to be derived from the differences in tests between the governing standards, which lead to conflict instead of clear guidance. The devices operate as a system, but are not type tested as a system with the only major common element being the “standard jumper bar”.
