scope:

SM 31000-7 covers metrological requirements and associated testing for current sensors used with electrical energy submeters. The standard applies to multiple sensor technologies with a variety of outputs. These sensors enable current measurement for AC and DC energy submetering.

The standard applies to indoor and outdoor applications and covers temporary and permanently installed sensors for AC and DC applications.

The SM 31000 standard is broken into the following parts:

a. SM 31000-1 General Requirements

b. SM 31000-2 AC Active Energy Accuracy

c. SM 31000-4 Additional Measurements Accuracy

d. SM 31000-5 DC Energy Accuracy

e. SM 31000-6 Power Quality Measurements and Accuracy

f. SM 31000-7 Current Sensor Accuracy

g. SM 31000-8 Demand Metering

h. SM 31000-9 Field Testing

i. SM 31000-10 Voltage Sensor Accuracy
