4 Negative Effects Of Reactive Power

The effect of harmonics on electrical power systems is well-documented. But there are other power quality issues to watch out for, such as an excessive increase in reactive power. Reactive power can be defined as the power that simply flows back and forth from the source to the end point without being utilized. This is the opposite of power factor, and it must be mitigated along with harmonics with harmonic filters and other tools. To further elaborate on why it must be removed, ADM Engineering Inc., a distributor of active harmonic filters and other power quality solutions, shares 4 unforeseen effects of reactive power on a system.

Consequences Of Reactive Power

Voltage Instability

With the presence of excess reactive power, the electrical system and the grid will experience voltage instability. With increased voltage in the system, appliances will malfunction as they are not designed to operate at such a high level. It can even lead to insulation breakdown in extreme situations.

Grid Instability

The presence of excess reactive power is also detrimental to the power grid itself, as it can cause voltage fluctuations and even an outright collapse, thereby causing blackouts in some cases.

Increase In Resonance And Harmonics

With an increase in reactive power, it can lead to a phenomenon known as resonance, wherein some frequencies match the frequency of the grid. This can lead to a major increase in harmonic distortion, and lead to additional stress on sensitive equipment in the form of overheating.

Increase In Energy Inefficiency

If the reactive power is too little or too much, it can also lead to an unforeseen increase in energy inefficiency. Therefore, waste of power and energy losses are natural outcomes with reactive power.
