By a suitable choice of utility frequency, both lighting and motor loads could be served.

Most other countries electrified their railways at the utility frequency of 50/60 Hz.

The frequency of the alternating current generated needs to match the local standard utility frequency.

Beacon designs and develops products aimed at utility frequency regulation for power grid operations.

Utility frequency (50/60 Hz) induction heating is used for many lower cost industrial applications as inverters are not required.

Utility frequency, frequency of the alternating current (AC) in an electric power grid.

Even by the middle of the 20th century, utility frequencies were still not entirely standardized at the now-common 50 Hz or 60 Hz.

Bearings are routinely heated in this way using utility frequency (50/60 Hz) and a laminated steel transformer type core passing through the centre of the bearing.

Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.

The Mariazeller railway in Lower Austria operates on single phase AC at a 25 Hz utility frequency.

To reduce the size of the model components, the network analyzer often was energized at a higher frequency than the 50 Hz or 60 Hz utility frequency.

The Fuji River also marks the divide of Japan's electrical grid, with the utility frequency of 50 hertz to the east, and 60 hertz to the west.

In power distribution networks AC/AC converters may be used to exchange power between utility frequency 50 Hz and 60 Hz power grids.

Synchronous clocks rely on the 50 or 60 Hz utility frequency of the AC electric power grid as a timing source, by driving the clock gears with a synchronous motor.

Operating frequencies range from utility frequency (50 or 60 Hz) to 400 kHz or higher, usually depending on the material being melted, the capacity (volume) of the furnace and the melting speed required.

(Although small frequency drifts will occur over any given several hours, grid operators actively adjust line frequency in later periods to compensate, thereby keeping motor-driven clocks accurate (see Utility frequency).)

The electrical utility frequency in western Japan, South Korea, Taiwan, the Philippines, Saudi Arabia, the United States, and several other countries in the Americas is 60 Hz.

It is related to the utility frequency at which the electricity distribution system operates, to avoid flicker resulting from the beat between the television screen deflection system and nearby mains generated magnetic fields.

Frequency response of a high gain amplifier is limited to about one-tenth the excitation frequency, although this is often mitigated by exciting magnetic amplifiers with currents at higher than utility frequency.

The rotation rate of the motor shaft is synchronized to the utility frequency; 60 cycles per second (Hz) in North and South America, 50 cycles per second in most other countries.

Conversely, frequencies used for some railway electrification systems were much lower (e.g. 16.7 Hz and 25 Hz) than normal utility frequencies (50 - 60 Hz) for historical reasons concerned mainly with the limitations of early electric traction motors.

Solar inverter - or PV inverter, converts the variable direct current output of a photovoltaic (PV) solar panel into a utility frequency alternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.
