Introduction to Power System Harmonics

The complete guide for understanding, identifying and controlling harmonics current.

Harmonics disrupts the power source’s current sinewave and hence adversely affects various power system components. According to most published surveys, 65-85 percent of power quality issues are caused by anything occurring within the facility, on the customer side of the point of common coupling. The supplied voltage may be incompatible with equipment within the facility due to the wiring or the loads themselves. As a result, the process is disrupted, productivity is slowed, and money is lost.

Harmonics disrupts the power source’s current sinewave and hence adversely affects various power system components. According to most published surveys, 65-85 percent of power quality issues are caused by anything occurring within the facility, on the customer side of the point of common coupling. The supplied voltage may be incompatible with equipment within the facility due to the wiring or the loads themselves. As a result, the process is disrupted, productivity is slowed, and money is lost.
