Technique

USED BY ELECTRIC COMPANY TO MONITOR AMOUNT OF ELECTRICITY USED FOR BILLING PURPOSES. AS SUCH, IT WAS OFTEN PLACED OUTSIDE THE HOME OR IN BASEMENT. CONSEQUENTLY,ACCURACY OF SUCH INSTRUMENTS, WHILE SUFFICIENTLY HIGH FOR THE PURPOSE, IS NOT SO IMPORTANT A 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 THEN BOTH COMMUTATOR WATTHOUR METERS AND MERCURY WATTHOUR METERS.
