Personnel in Hope Water & Light’s Electric Metering
Department are responsible for monitoring Electric meter accuracy and
performing tests to ensure residential, commercial and industrial rated meters
are meeting specifications. In addition, personnel install Current Transformer
(CT) rated meter sites and perform a series of tests to verify all components
of a CT meter site are meeting specifications. Hope Water & Light values
the accuracy of the systems and meters that are installed at customer locations
and we strive to ensure all meter systems are performing within specifications.
Hope Water &
Light’s test procedure includes visual inspection of the meter and its location
for proper installation, meter type, and physical damage. Our procedure also
includes a calibration test at our meter shop to determine the accuracy of the
meter and any needed adjustment of the meter to within acceptable limits before
returning it into our system. Should a meter require testing, we normally
replace your meter at the time of removal to eliminate additional trips and
interruption of your service.
The Arkansas Public
Service Commission requires that the meter shall not have an error of more than
plus 2% or minus 4% at light load (5-10% of capacity), or plus or minus 2% at
heavy load (60-200% of capacity). We test our meters at 10% for light load and
100% for heavy load.
