Electrical Submeter—Current Sensor Accuracy ANSI/NEMA SM 31000-7-2021 is a new standard that covers metrological requirements and associated testing for current sensors used with electrical energy submeters to assess accuracy. It applies to multiple sensor technologies with a variety of outputs. These sensors enable current measurement for AC and DC electrical submetering.
The entire SM 31000 standards series assists policymakers and facility managers as they expand the usage of electrical submeters in energy management applications by giving them confidence in quality measurement.
This standard series is written for Nationally Recognized Testing Laboratories (NRTL) U.S. Department of Energy, state and local energy departments, facility managers, and electrical engineering firms.
It is available on the NEMA Standards Store for $67.
