In extreme cases, if you notice a really low power factor, you could have what's known as three phase power imbalance, which can be due to improper wiring. If you do have an imbalance, your very expensive equipment is working against itself, creating a lot of wear and tear on the motors, shortening its life span, and generating a lot of heat, which could be a safety hazard.

By contrast, a wholly inductive ac circuit theoretically could have a power factor that is very low or zero, if the real power approaches or equals zero. Although many industrial circuits have both resistive and inductive components, it will take more current to deliver the required amount of real power to a plant that has a low power factor due to induction motors.
