    4-3 DESCRIPTION of GENERATOR 4-3-l PRIMARY EXCITING ACTION (RGV12000) When the generator is started, the perma- nent magnet on the engine rotates to genera- tor a voltage in the exciting coil. This voltage is regulated by a diode in the AVR to feed a current to the generator field coil.
  • Page 20 4-3-3 CURRENT TRANSFORMER When the engine starts, a permanent magnet implanted in the rotor rotates, creating voltage in the main coil (MC). When a load makes contact with the coil, the load current passing through the primary coil of current transformer causes a magnetizing current to flow in ratio to the load current flowing through the current transformer primary coil.

    5. SAFETY PRECAUTIONS 1. Use extreme caution near fuel. A constant Do not fill the fuel tank while the engine is running. Do not smoke or use open flame near the fuel tank. Be careful not to spill fuel when refueling. If spilt, wipe it and let dry before starting the engine.

  • Page 22: Range Of Applications

    6. 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 show- ing their rated voltage, frequency, and power consumption(input wattage).
  • Page 23 NOTE 2 : Motor-driven appliances mentioned in lets (3) and (4) vary in their required motor starting power depending on the kind of motor and start-up load. If it is difficult to determine the optimum generator capaciv, select a generator with a larger capacity. (5) Appliances without any indication...
