North American transformers usually power homes at 240 volts, similar to Europe's 230 volts. It is the split-phase that allows use of 120 volts in the home. Japan's utility frequencies are 50 Hz and 60 Hz. In the electricity sector in Japan, the standard voltage is 100 V, with both 50 and 60 Hz AC frequencies being used Basically, the Range A service voltage range is plus or minus 5% of nominal. The Range B utilization voltage range is plus 6% to minus 13% of nominal. For range A, the occurrence of service voltages outside of these limits should be infrequent. Utilization equipment shall be designed and rated to give fully satisfactory performanc The four major voltage classes are 5, 15, 25, and 35 kV. A voltage class is a term applied to a set of distribution voltages and the equipment common to them; it is not the actual system voltage. For example, a 15-kV insulator is suitable for application on any 15-kV class voltage, including 12.47 kV, 13.2 kV, and 13.8 kV According to the U.S. Energy Information Administration Exit, the U.S. power grid is made up of over 7,300 power plants, nearly 160,000 miles of high-voltage power lines, and millions of miles of low-voltage power lines and distribution transformers, connecting 145 million customers throughout the country (EIA, 2016) Many manufacturers design equipment with varying voltages in mind, and may list an ability to handle input ranging from 110-240 volts, indicating that it will work in Europe and the United States. In addition, the equipment is usually rated at 50/60 hertz, and will function on either cycle

In the U.S.: we use 120/240. The first power systems were 110 volts. Edison chose that as a good compromise voltage to make his light bulb work well (this voltage was high enough that the bulb gave off a good amount of light, but this voltage was. For single phase voltage, the voltage is expressed as a Line to Neutral voltage between two power conductors (plus a safety ground). The neutral conductor is normally at ground potential while the Line conductor is a sinusoidal AC voltage with an RMS value of 120Vac. That means the peak of the AC voltage alternates from +169.7Vac to -169.7Vac every 16.667 msec on the US 60Hz grid frequency.

TenneT transmits electricity at 110,000 volts (110 kV) and higher. In Germany, the operators of the high-voltage grids, i.e. the 220 and 380 kV grids, are designated as Transmission System Operators. Our high-voltage grid has a frequency of 50 Hz, in line with European standards Short answer: The range is usually held within ±0.5%, so its from 59.7Hz to 60.3Hz for a 60Hz grid. Long answer: Frequency is regulated tightly because it's how the overall load in the grid is controlled. If there's a runaway to lower frequencies, that usually means there is a short-circuit near a major power station or hub Transmission-level voltages are typically at or above 110,000 volts or 110 kV, with some transmission lines carrying voltages as high as 765 kV . Power generators, however, produce electricity at low voltages.

Voltage can readily be taken up to about 765,000 volts (765 kV) for an AC powerline (this is the current maximum AC voltage in the US) but beyond that, power dissipation through dielectric loss becomes significant. (Dielectric losses are caused when dipoles in matter align with a changing local electric field. As the polar structures turn to follow the field, the movement causes local heating. This is the basis of microwave ovens. The dielectric loss during transmission is equal to the total. Three Grids in the United States. There are three separate grids that actually come together to create the United State?s complex full network. There is the Eastern Grid, the Western Grid and the Texas (ERCOT) Grid, with the Eastern Grid being the largest of the three.
