500kv gil process

This paper is an in-depth analysis on a 500kV GIL fault resulting in the tripping operation of a substation chief transformer. The causes of the accident are discussed from several aspects, such as insulation defect, design of gas inlet port, and effect of temperature on the water in the GIL.

    The GIL, or Global Interpreter Lock, is a boolean value in the Python interpreter, protected by a mutex. The lock is used by the core bytecode evaluation loop in CPython to set which thread is currently executing statements. Another issue is that file handles belong to the process, so if you have a file open for writing in one interpreter
