In the United States, power transmission is, variously, 230 kV to 500 kV, with less than 230 kV or more than 500 kV as exceptions. The Western Interconnection has two primary interchange voltages: 500 kV AC at 60 Hz, and ±500 kV (1,000 kV net) DC from North to South ( Columbia River to Southern California ) and Northeast to Southwest (Utah to ...
The new Celilo Converter Station went into service in January 2016 after the entire terminal had been replaced with a new two-converter terminal rated ±560 kV 3410 A (3800 MW), while the Oregon section of the transmission line was upgraded to ±520 kV and 3,220 MW. [3] [4]
The area required for a converter station is much larger than a conventional transformer, for example a site with a transmission rating of 600 megawatts and a transmission voltage of 400 kV is approximately 300 x 300 metres (1000 x 1000 feet).
Rural electrification systems tend to use higher distribution voltages because of the longer distances covered by distribution lines (see Rural Electrification Administration). 7.2, 12.47, 25, and 34.5 kV distribution is common in the United States; 11 kV and 33 kV are common in the UK, Australia and New Zealand; 11 kV and 22 kV are common in ...
HVDC converters capable of converting up to two gigawatts (GW) [2] and with voltage ratings of up to 900 kilovolts (kV) [3] have been built, and even higher ratings are technically feasible. A complete converter station may contain several such converters in series and/or parallel to achieve total system DC voltage ratings of up to 1,100 kV.

In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.
