THIS ONE WAS KEPT AT THE DEPT. OF TRADE AND COMMERCE, STANDARDSBRANCH, IN OTTAWA AS PART OF ITS LEGAL OBLIGATIONS TO TEST AND MAINTAIN EXAMPLES OF METERS SOLD COMMERCIALLY IN CANADA./ ALSO TO DETERMINE THE STANDARD FOR THIS PARTICULAR MODEL OF WATT-HOUR METER.

Function

A METER WHICH INTEGRATES, OR SUMS UP THE SUCCESSIVE VALUES OF POWER SUPPLIED THROUGH IT TO A DISTRIBUTING CIRCUIT & REGISTERS THE SUMS OF THESE VALUES IN COMMERCIAL UNITS: IT MEASURES THE TOTAL ENERGY USED.

Technical

ARTIFACT WAS USED BY ELECTRIC COMPANY TO MONITOR THE AMOUNT OF ELECTRICITY USED FOR BILLING PURPOSES. AS SUCH, IT WAS OFTEN PLACED OUTSIDE THE HOME OR IN THE BASEMENT. CONSEQUENTLY, THE ACCURACY OF SUCH INSTRUMENTS, WHILE SUFFICIENTLY HIGH FOR THE PURPOSE, IS NOT SO IMPORTANTA FACTOR AS PERHAPS SOME OTHER QUALITIES; SUCH AS RUGGEDNESS, READABILITY, AND LOW COST. THE INDUCTION WATTHOUR METER IS SIMPLE IN ITS STRUCTURAL ASSEMBLY. THIS INSTRUMENT IS ACCURATE OVER A WIDE RANGE OF LOAD, POWER FACTOR, VOLTAGE, FREQUENCY, AND TEMPERATURE. THE ONLY DRAWBACK OF THIS INSTRUMENT IS THAT, AS IT RELIES ON INDUCTION, IT CANNOT BE USED IN DIRECT CURRENT CIRCUITS. IT IS, HOWEVER, THE LEADING CHOICE FOR ALTERNATING CURRENT CIRCUITS. IT IS SIMPLER, COSTS LESS, AND REQUIRES LESS MAINTENANCE THAN BOTH COMMUTATOR WATTHOUR METERS AND MERCURY WATTHOUR METERS.
