That is, the product of voltage and current at the output or input end. The symbol for apparent power is represented by S, and the unit is volt-ampere (VA), kilovolt-ampere (kVA). or megavolt-ampere (MVA), etc., expressed in Used to express the capacity of the generator.
Active power is the electrical power necessary to maintain the normal operation of electrical equipment, that is, the electrical power that converts electrical energy into other forms of energy (energy mechanics, light energy, thermal energy). The symbol for active power is represented by P and units include watts (W), kilowatts (kW) or megawatts (MW). It is generally calculated using (apparent power × power factor).
Reactive power: Reactive power is relatively abstract. This is the electrical energy used to exchange electric fields and fieldsmagnetic fields within a circuit and for establishing and maintaining magnetic fields in electrical equipment. It does not perform work externally, but transforms into other forms of energy. Any electrical equipment with electromagnetic coils consumes reactive power to establish a magnetic field. The symbol for reactive power is represented by Q, and the unit is Var (Var), kVar (kVar) or megavar (MVar), etc.

Notes:
1. When installing the generator, it must be stable and firm. When using outdoors, a shed should be constructed and well ventilated.
2. No oil or other flammable objects should be placed nearby and a fire extinguisher village should be installed. In the event of a fire, the power supply should be cut off and ignited immediately.
3. The generator connection parts must be firm andreliable, rotating parts must have protective devices, output lines must be well insulated, and the instructions for each instrument must be clear.
4. During operation, the operator is not allowed to leave the machine. If a fault is detected, stop the machine immediately, investigate the cause, then continue working once the fault has been eliminated.
5. Work under tension is strictly prohibited. Before overhauling electrical equipment, the power supply should be cut off, an eye-catching warning sign should be hung, and a dedicated person should be appointed to monitor it.
