Excerpt from Watthour Meter
Considerable information may be derived from various sources relative to the watthour meter. Realizing the desirability and advantage of collecting and publishing such information in concrete form, the authors have endeavored to describe the prominent types and the best usage of modern domestic watt-hour meters.
It has been the intention to prepare the facts in a form which will impart to the central station manager, the practical meter man and to the student alike, information which will be edifying and serviceable for reference and as a guide for the proper installation, connection, testing and maintenance of that most vital factor in the distributing system - the watthour meter.
Especial attention has been given the induction type and a brief but concise explanation of its theory and operation has been made without the use of higher mathematics. Maintenance and testing are also treated in detail with the dominant idea of giving the practical man assistance in modern, effective and quick methods of obtaining efficient results. Comprehensive tables of testing constants and formula are incorporated in Chapter VIII.
