ground, with opposite polarity. Since these conductors must be insulated for the full voltage, transmission line cost is higher than a monopole with a return conductor, but this is more than com pensated for by its advantages, such as negligible earth-current flow, lower abso ute current rating (each line carries only half the current for the same power), fault tolerance and so on. Gotland 2 and 3, with a total rating of 2 x 130MW/t 150 kV featured new water-cooled converters This bipolar link has provided extremely good availability with no interruption of power transmission in 10 years
