West Kentucky Rural Electric Automated Meter Testing Standards

All the automated meters purchased by WKRECC are manufactured and tested in accordance with the following standards:

ANSI C12.1 American National Standard Code for Electricity Metering, which establishes acceptable performance criteria for AC watthour meters, demand meters, demand registers, pulse devices and auxiliary devices. It establishes acceptable in-service performance levels for meters and devices used in revenue metering.

C12.10 American National Standard Code for Electromechanical Watt-hour Meters, covering the physical aspects of watt-hour meters including ratings, internal wiring arrangements, pertinent dimensions, markings and other general specifications. C12.10 references ANSI C12.1 and ANSI C12.20 for performance requirements. Dimensions and other relevant specifications are coordinated ANSI C12.7 that address meter sockets.

C12.20 American National Standard Code for Electricity Meters 0.2 and 0.5 Accuracy Class, establishes the physical aspects and performance criteria for a meter's accuracy class. It supersedes certain details in ANSI C12.1 and ANSI C12.10. and specifically address meters intended to operate in 0.2% or 0.5% accuracy class.

While compliance with C12.20 exceeds the requirements for residential and small commercial metering, WKRECC voluntarily complies and requires testing to the Class .2 criteria having ± 0.2% accuracy range.
