Inductive Load Bank

Power Factor Correction Systems - Banks

Low-voltage inductive load banks are essential for optimising reactive power management in electrical networks operating at low voltages. These systems are widely used in industrial plants and large commercial buildings.

Facilities with lengthy medium-voltage underground cables or powerful uninterruptible power supplies often exhibit capacitive characteristics, which can be effectively compensated for by inductive compensation systems. Additionally, some solar power generation facilities may also require inductive compensation systems. The power factor correction system comprises stages of inductive load reactors.

What is Inductive Power?

Inductive power is the reactive power generated by inductive loads, which create magnetic fields in alternating current circuits. This power is vital for energy transmission and magnetic field generation, but it does not contribute directly to productive work.

Inductive loads cause a lag in current relative to voltage, reducing the power factor of the system. This inevitably results in energy losses and excessive loading on the grid. To migigate the negative effects of inductive power, capacitive power (capacitor bank) is frequently used to enhance energy efficiency and reduce transmission losses.

What is Inductive Power Factor Correction?

Inductive power factor correction is the solution to reactive power problems caused by capacitive loads in electrical grids. This approach guarantees the optimal utilisation of energy and a reduction in associated expenses.

Benefits of Inductive Load Banks

Inductive power factor correction systems offer specific benefits by mitigating reactive power problems stemming from capacitive loads within electrical networks.

  1. Mitigating Capacitive Loads in Cables and To Assess the Associated Costs:
    Extended cable runs generate capacitive reactive power, resulting in additional charges on the electricity bill.
    Inductive power factor correction systems are designed to counteract the effects of capacitive reactive power through the use of shunt reactors, thereby eliminating the associated charges.
  2. Preventing Capacitive Reactive Charges in Solar Power Facilities:
    Solar power plants often produce excess electricity during the day, which they sell back to the grid.
    At night, they must purchase electricity from the grid, which may result in the incurrence of capacitive reactive charges.
    Inductive load banks are automatically activated when electricity is sold to eliminate these charges during zero-consumption periods.
  3. Neutralising reactive power from large, high-capacity UPS systems:
    Large UPSs are known to generate capacitive reactive power. Inductive load banks have been developed to neutralise this capacitive reactive power generated by UPSs, thereby eliminating any capacitive reactive energy cost.

Characteristics of Inductive Load Banks

  1. Modular Design: The modular design allows for capacity adjustments to be made in accordance with the specific requirements of the user, thereby providing adaptability to a range of load profiles and simplifying the installation and maintenance processes.
  2. Copper Main Busbar: Inductive load banks are equipped with main copper busbars that are capable of withstanding high currents. This ensures that the system can operate reliably for an extended period of time. Furthermore, copper busbars facilitate the cooling of the system by optimising heat dissipation.
  3. Efficient configuration placing the busbar at the top, followed by a sequence of components including fuse switching disconnector, contactor, shunt reactor: This specific configuration serves to enhance the system’s overall safety and functionality. The fuse switch provides a safeguard against overcurrent incidents within the system. The contactor is employed for the purpose of switching reactors on and off, thereby providing automated control of the system. The shunt reactor serves to optimise the efficiency of the system, compensating for the reactive power generated by capacitive loads.
