An overhead electric distribution system typically contains which type of reactive power?

In an overhead electric distribution system, lagging vars (reactive power) are typically present due to the inductive loads frequently connected to the system, such as motors, transformers, and other inductive equipment. These loads consume reactive power, which is characterized by a delay or lag in the current relative to the voltage waveforms.

The presence of lagging vars is essential for voltage regulation within the system, as they help support the voltage levels needed to ensure reliable power delivery. This is why utilities often aim to manage or compensate for lagging reactive power by installing capacitor banks or other forms of reactive power compensation to improve overall system efficiency and maintain higher voltage levels.

On the other hand, leading vars represent capacitive loads and are generally used in specific scenarios aimed at correcting power factor issues but are not the primary reactive power type in overhead distribution systems, which predominantly deal with inductive loads. Net vars and phantom vars are not standard descriptions used in the context of typical reactive power in electrical distribution systems. Thus, the presence of lagging vars is characteristic of the reactive power used in such systems.
