What equipment is commonly used to counteract inductive loads in the power system?

Shunt capacitors are employed to counteract inductive loads in the power system primarily because they provide reactive power support. Inductive loads, such as motors and transformers, consume reactive power which can lead to a lagging power factor in the system. This lagging power factor can result in inefficient power delivery and increased losses. Shunt capacitors, when connected to the system, supply leading reactive power, which helps to correct the power factor by offsetting the lagging reactive power demand of the inductive loads.

The placement of shunt capacitors in the system allows for improved voltage stability, reduced losses, and enhanced overall system performance by balancing the reactive power flow. This is particularly critical in maintaining the efficiency and reliability of the power system, especially during periods of high inductive load demand.

In contrast, induction motors primarily serve as load devices that draw reactive power rather than counteracting it. Transformers, while critical in voltage conversion and regulation, do not address the need for power factor correction directly. Voltage regulators typically manage voltage levels rather than directly counteract inductive loads. Thus, shunt capacitors stand out as the most appropriate equipment for this specific purpose.
