They connect only through tie lines where power must be converted from alternating current to direct current and back again. |
An integral inverter changes the direct current to alternating current for transmission into the facility's electrical distribution systems. |
There is a alternating current, instead of a direct current within the bobbin because of the motion of the string. |
The inverter changes the solar direct current into the alternating current used by most household appliances. |
Ac power is converted to a high-voltage Dc current, which an oscillator or resonator outputs as an alternating current. |
In fact, while the national grid relies on alternating current for transmitting electrons, the internal Texas grid transmits via direct current. |
