THIS MULTIPLIER WHETHER USED FOR MEASURING POWER (WATT METER/KILOWATT METER) OR ENERGY (KILOWATT-HOUR METER) ARE USUALLY USED FOR HIGH AMPERE LOAD UNLIKE IN RESIDENTIAL APPLICATION THAT METERING ARE DIRECTLY CONNECTED TO SUPPLY LINE. THIS MULTIPLIER IS OBTAINED FROM THE RATIO OF CURRENT TRANSFORMER USED, FOR EXAMPLE 300:5 THIS MEANS YOU HAVE TO MULTIPLY YOUR GATHERED READINGS TO 60 TO HAVE THE ACTUAL CONSUMPTION. THE CURRENT TRANSFORMER (INSTRUMENT TRANSFORMER) IS NORMALLY SHAPED LIKE "DOUGHNUT" WHERE CABLE PASS THROUGH OR RECTANGULAR SHAPED FOR BUSBARS TO MEASURE ACTUAL LINE CURRENT AND COMBINED WITH POTENTIAL (VOLTAGE) TRANSFORMER FOR REMOTE METERING AND SYSTEM PROTECTION PURPOSES IN COMMERCIAL & INDUSTRIAL APPLICATIONS OR WHERE LOAD ARE HIGHER AND FOR SAFETY PURPOSES TO PERSONNEL/TECHNICIANS.

Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?

There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.


State the meaning of multiplying factor of wattmeter and with suitable example explain how it is determined?

watt meter is constructed such that it read only power on a single scale. Only single scale will available to read the measured power. In order to take the accurate reading just we measure the reading and we will multiple along with factor called multiplication factor. That's depends on on which voltage knob we connected and also the current. Multiplication factor can be determined by: Multiplication factor =(voltage range*current range*pf)/Max scale deflection.
