The intent of this volume is to provide general information on theory, checks, tests, adjustments, and records which will serve as a simple and convenient ready-reference guide for testing and servicing meters in the field. This volume is confined to the type of watt-hour meter most commonly used on Reclamation power systems-the 2-,2-1/2-, and 3-element alternating-current, induction watt-hour meter rated at 115 volts and 2.5 or 5 amperes used with instrument transformers for metering relatively large blocks of power. However, the material herein will provide sufficent information for testing single-phase and polyphase meters of other current and voltage ratings by simple application of the principles discussed. To supplement the general information in this volume, an appendix devoted specifically to revenue metering has been included.
