An energy meter is designed to have 100 revolutions of the disc per unit of energy consumed. The energy consumed by the load-carrying 50 A at 230 V and 0.8 power factor. Find the percentage error if the meter actually makes 950 revolutions.
Boards on which various control accessories like energy meter, iron-clad switch, fuses, etc. are housed are called ______ boards.
Direction: It consists of two statements, one labeled as ‘Statement (I)’ and the others as ‘Statement (II)’. You are to examine these two statements carefully and select the answer using the codes given below: Statement (I): A Watt-hour meter must be calibrated at both full-rated load as well as at 10% of rated load.Statement (II): The source of error at full load is inaccurate damping and at light loads, the torque is not exactly proportional to load.
Creep error may occur induction type energy meter due to
If an energy meter disc makes 10 revolutions in 100 sec when a load of 450 W is connected to it, the meter constant (in rev / kW-h) will be:
A domestic load consists of 10 lamps of 100 W each, three fans of 60 W each and two heaters of 1 kW each, all the loads operating for 1 hour. Energy consumed is measured using an energy-meter having a constant of 1500 revolutions per kWh. The number of revolutions recorded by the meter is 4500. The percentage error in the energy-meter reading is:
