| Abstract: | Several common problems in daily running of relay protection in Guangdong power system are briefly discussed, which include the naming of pilot protection, handling of busbar current different protection during the maintenance of a potential transformer in a double-bus scheme substation, what to do when 220 kV bus protection and line main protection are out, points for attention as to the use of by-pass circuit, and treatment during charging on single supply side of a 220 kV line, etc. The solutions for the above problems are explained theoretically as well. |
