Current through Vol. 42, No. 7, December 16, 2024

Section 165:35-15-15 - Installation tests

(a)New meters. New meters shall be inspected and tested in a meter testing facility, or by the manufacturer, either on a one hundred percent (100%) basis or on a statistical sampling basis acceptable to the Commission, and appropriate action shall be taken by the utility to assure that the meters conform to the accuracy requirements outlined in this Chapter.

(b)Meters installed with instrument transformers. Meters installed with instrument transformers shall be tested on a one hundred percent (100%) basis and adjusted to conform to the accuracy requirement outlined in this Chapter prior to installation. In addition, a complete inspection shall be made of the wiring after installation to assure proper connections for metering.

(c)Separate test of meters and transformers. The watt-hour meters may be tested independently of instrument transformers, provided the transformer ratios and phase angles have been determined and are taken into account in the calibration of the meters. The transformer errors may be neglected in the calibration of the meters if instrument transformers are used that conform to the 0.3 accuracy class limits of the ANSI requirements with the actual secondary burden.
