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 12 - A three phase kWh meter, three-wire, two-stator, self-contained meter. To measure the loading of a 3-wire wye or delta service configuration transformers.
Form 14 - A three phase kWh meter, four-wire wye, two-stator, self-contained meter. To measure the loading of a 4-wire wye service configuration transformers.
Form 15 - A three phase kWh meter, four-wire delta, two-stator, self-contained meter. To measure the loading of a 4-wire delta service configuration transformers.
Form 16 - A three phase kWh meter, four-wire wye, three-stator, self-contained meter. To measure the loading of a 4-wire wye service configuration transformers.
