  • Reactive power compensation

    Reactive power compensation

    Apr , 12 2024
    The electrical equipment of the power system will produce active power and reactive power when in use. Active power converts electrical energy into mechanical, thermal, chemical, or acoustic energy, while reactive power converts electrical energy into another form of energy, such as electrical energy occupied by electromagnetic components to build up a magnetic field. The hazards of reactive power...

  • What happens when the neutral and ground wires are reversed?

    What happens when the neutral and ground wires are reversed?

    Apr , 12 2024
    AC power is basically generated by the generator in the power plant. The generator has three-phase windings with an electrical angle difference of 120 ° between them. When connected in a star connection method, there is a common point between the three windings, called the neutral point. This neutral point N is usually connected to the ground PE, so it is called PEN together. If the output current...

  • Advantages of Solar Gel batteries

    Advantages of Solar Gel batteries

    Apr , 02 2024
    Are Gel Batteries Better For Solar? The modern gel battery was invented in 1957. Gel batteries are one of two sealed lead acid batteries, the other being an AGM battery. Sealed lead acid batteries are distinct from other lead acid batteries in that they are maintenance-free What’s in a gel battery? A gel battery is a dry battery since it doesn’t use a liquid electrolyte. In a gel battery, the elec...

  • Effect of low temperature on battery performance

    Effect of low temperature on battery performance

    Mar , 30 2024
    When the lithium-ion battery is in a low temperature state, its available capacity is reduced and the charge and discharge power is limited. If the power is not limited, it will cause the evolution of lithium ions inside the battery, which will lead to irreversible attenuation of the battery capacity, and will bury a safety hazard for the use of the battery. The lower the ambient temperature, the ...
