Power frequency is the frequency at which alternating current mains electricity is supplied and distributed, a standard value of 60 hertz in the United States.
Power frequency is the rate at which the alternating current of mains electricity cycles, expressed in hertz. In the United States the standard power frequency is 60 hertz, meaning the current reverses direction sixty times per second. Equipment and systems are designed to operate at the power frequency of the region where they are used.
The power frequency affects the design and behavior of electrical equipment, including motors, transformers, and the inductive and capacitive characteristics of circuits. Because the frequency is standardized, devices can be built to work consistently with the supply they receive.
In commercial and industrial systems, the power frequency is the baseline for power distribution, and the cable carrying power operates at this frequency. Understanding the power frequency is part of understanding how power is delivered throughout a facility.
Because the power frequency is standardized, devices can be built to work consistently with the supply they receive, and it shapes the design and behavior of equipment, including motors, transformers, and the inductive and capacitive characteristics of circuits operating at that rate.
Recognizing how the standardized power frequency shapes equipment and distribution helps illustrate the baseline at which a facility's power systems are designed to operate.
At Windy City Wire, the focus on properly rated low-voltage and power cable supports distribution at the standard power frequency. Supplying dependable cable for the circuits a facility runs helps ensure reliable operation of systems supplied at 60 hertz.
