3. RANGE OF APPLICATIONS Generally, the power rating of an electrical appliance indicates the amount of work that can be done by it. The electric power required for operating an electrical appliance is not always equal to the output wattage of the appliance. The electrical appliances generally have a label showing their rated voltage, frequency, and power consumption (input wattage). The power consumption of an electrical appliance is the power necessary for using it. When using a generator for

(5) Appliances without any indication as to power consumption Some appliances have no indication as to power consumption; but instead the work load (output) is indicated. In such a case, power consumption is to be worked out according to the numerical formula mentioned below. (Output of electrical appliance) = (Power consumption) (Efficiency) Efficiencies of some electrical appliances are as follows : Single-phase motor . . . . . .0.6 to 0.75 (The smaller the motor, the lower the efficiency) Flu

NOTES : Wiring between generator and electrical appliances 1. Allowable current of cable Use a cable with an allowable current that is higher than the rated input current of the load (electrical appliance). If the input current is higher than the allowable current of the cable used, the cable will become excessively heated and deteriorate the insulation, possibly burning it out. The table below shows cables and their allowable currents for your reference. 2. Cable length If a long cable is used,

4. MEASURING AND CHECKING PROCEDURES 4-1) MEASURING INSTRUMENTS (1) VOLTMETER AC voltmeter is necessary. The approximate AC voltage ranges of the voltmeters to be used for various types of generators are as follows : 0 to 150 V : Type with an output voltage of 110 or 120 V 0 to 300 V : Type with an output voltage of 220, 230 or 240 V For AC For DC 0 to 150 V, 0 to 330 V : Dual voltage type (2) AMMETER AC ammeter is necessary. An AC ammeter with a range that can be changed according to the curr

(4) CIRCUIT TESTER For measuring resistance, etc. NOTE : The ordinary circuit tester may cause erroneous readings due to their measuring method. Use a high-grade, precise circuit tester to check the generator components. (5) MEAGER TESTER Used for measuring generator insulation resistance. Select the one with testing voltage range of 500V. (6) TACHOMETER Use the contactless type tacho meter for checking engine speed. – 15 –
