Electrical power is made up of two components: active power and reactive power. Active power is referred to as the 'useful' or working energy source, which enables the electrical equipment to perform its function. Reactive power, however, does not perform 'useful' work. Its only function is to develop the electromagnetic fields (EMFs) in order to grind the induction windings of the motor.

The imop works by reclaiming, storing and then supplying the reactive power element of electricity to inductive motors and loads. As the electrical equipment operates, this reactive power is 'pulled and pushed' to and from the imop by the motor. Reactive power is then recycled by the imop, which is able to supply it on the spot without having to draw it from the national grid. Savings on electricity bills is just one of the benefits because the motors will also run cooler and more efficiently, and of course require less maintenance. Since cooler motors live considerably longer there is the added bonus of reduced expenditure on capital purchases.

Myths and Misconceptions

Anyone who has global power factor correction installed may believe that they have already increased their building's efficiency. This is a common misconception. Global power factor correction only improves the power factor (or pf) from where the unit is installed back to the electricity supplier. In fact, the only savings that are being made are between the global pf correction unit and the meter. Often these are installed next to each other anyway!

Unlike global power factor correction, imops ensure power savings are made throughout the infrastructure of the building. The fact that they are located on individual pumps etc means that they are able to make the electrical savings from each point, throughout the building infrastructure back to the meter.
