KWHR METERS FORMS 5, 6, 8, & 9 FOR DIFFERENT TRANSFORMER CONFIGURATIONS PART2

How does a three-phase kilowatt-hour meter being connected to its distribution transformers?

As promised, here are the different illustrations of how various three-phase electric kwhr meters type are wired correspoding to its transformer-bank configurations. A simple electrical schematic showing the transformer configuration in its meter type connection will be carefully illustrated below;

Form 5 - A three phase kWh meter, three-wire, two-stator, instrument rated meter. To measure the loading of a 3-wire wye or delta service configuration transformers, with bigger loads that needs instrument transformers.

Form 6 - A three phase kWh meter, four-wire wye, two-stator, instrument rated meter. To measure the loading of a 4-wire wye service configuration transformers, with bigger loads that needs instrument transformers.

Form 8 - A three phase kWh meter, four-wire delta, two-stator, instrument rated meter.To measure the loading of a 4-wire delta service configuration transformers, with bigger loads that needs instrument transformers.

Form 9 - A three phase kWh meter, four-wire wye, three-stator, instrument rated meter. To measure the loading of a 4-wire wye service configuration transformers, with bigger loads that needs instrument transformers.
