And makes it much easier to stabilize the power flow between regions. (A 2000 km long transmission line makes for all sorts of interesting things with reactive sources at one end and reactive loads at the other). The Pacific DC Intertie terminates at Sylmar (in the San Fernando Valley, about 20 miles north of downtown Los Angeles).. +/-500kV at 3000A. They just recently (last 10 years) changed from mercury pool inverters to solid state thyristors. Both are quite impressive. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
