5.Lhpplianceswithout any indication as to power consumption

Some appliances have no indication as to power consumption: but instead the work load (outpurj is indicated. In such a case.power consumption is to be worked out according to the numerical formula indicated below.

(Output of slectrical appliance) = (Power consumption) (Efficiency,l

Efficiencies of some electrical appliances are as follows:

Single-phasemotor _ . . _ . . 0.6 - 0.75 -

- The smaller the capacity. the wors2 the efficiency.

Three-phase motor . _ . . _ . . . . . 0.65 - 0.9 ~

and dce versa.

Fluorescent lamp . . . . . . . _ . . 0.7 - 0.8

Example 1: X 4ON fluorescsnt lamp means that its luminous output is 4OK. Its efficiency is 0.7 and accordin&. pow- er consumption will be 40 - 0.7 = 5XV. As explained in Item 2. multiply this pow2r consumption value of 57lV b>- 1.’ - 2 and you will get th2 figure of necessar>-capacity of a generator. In other Lvords.a gen- erator with a rated output of lOOON-capacity- can li@t nine to fourteen 4017 tluorescent lamps.

Example 2: GeneraIl!- speakin,0. a -lOON-motor means that its work load is -lOON-.Efficiency oi this motor is 0.7 and power consumption Lvill be 100 +- 0.7 = 57OK. W12n this motor 1sus2d ior a motor-driven tool. the capa- city of the generator should be multipled b>- 1.Z to 3 and 5701V as explained in Item 3. Moreover. when this motor is used for the submerged pump or air compr2sser. it requir2s 3 - 5 times as powveriul a genera- tor as in Item 4.
