Sentence examples for industrial frequency from inspiring English sources

Particularly influential on both counts was the successful French pioneering of electrification with a direct supply of high-voltage alternating current at the industrial frequency.

In general, a low earthing resistance at industrial frequency is recommended, usually below 10 (mathrm{Omega }).

Such a new traction power supply system allows the industrial frequency single-phase AC power supply system of an electrified railway to achieve no phase split.

Using the industrial frequency AC, the given traction power supply system can connect to a utility grid directly and thus gains economic, reliable, and strong power supply.

The proposed industrial frequency single-phase AC traction power supply system for the urban rail transit consists of a main substation (MSS) and cable traction network (CTN).

Looking at the traction power supply mode in Germany, the power supply frequency is different from industrial frequency (50/60 Hz) of power systems.

In the early decades of high-voltage alternating current electrification, available alternating-current motors were not suitable for operation with alternating current of the standard commercial or industrial frequencies (50 hertz [cycles per second] in Europe; 60 hertz in the United States and parts of Japan).

To avoid complications and difficulties mentioned above, a new industrial frequency-based single-phase AC traction power supply system using 35 kV cables is proposed in this paper for urban rail transit, due to the fact that 35 kV cables have widely been used in metro systems.
