Self-Contained Polyphase Meter - Videos and Related Books
This 33-minute video demonstrates accuracy tests on a three stator self-contained polyphase meter and a two-and-a-half stator (split element) self-contained polyphase meter in the field. This demonstration includes details on bypassing the meter and connecting test equipment for both individual element and series element testing. In addition, a procedure for bringing the meter into acceptable accuracy limits is demonstrated.
Basic Meter Testing – 10 minutes
Describes accuracy tests typically performed on self-contained, polyphase meters. Identifies the basic test equipment used for testing these meters. Describes how a meter and the appropriate test equipment are connected to perform each type of accuracy test.
Testing a Polyphase Meter – 12 minutes
Describes basic preparations for testing a polyphase meter. Describes how series element tests may be performed on a three-phase, four-wire, three-stator meter. Explains how individual element tests may be performed on a three-phase, four-wire, three-stator meter. Describes the basic layout of a three-phase, four-wire, two-and-a-half-stator meter. Shows how series element tests may be performed on a three-phase, four-wire, two-and-a-half-stator meter. Explains how to perform individual element tests on a three-phase, four-wire, two-and-a-half-stator meter.
Polyphase Meter Adjustments – 11 minutes
Describes preliminary steps typically taken before adjustments are made to a polyphase meter. Describes how adjustments can be made to a three-phase, four-wire, three-stator meter.
