As required for routine tests of gas-insulated metal-enclosed switchgear, it is necessary to ensure that each equipment unit undergoes systematic routine tests before leaving the factory. These tests (also known as production tests) core on confirming the consistency between the equipment's operating status and design requirements as well as type-test parameters, serving as an indispensable quality control link after assembly. Test parameters are directly derived from type-test data, so routine

High Voltage Gas Insulted Switchgear (GIS) Field Testing According to IEEE C37.122The final assembly of the gas - insulated substation (GIS) takes place in the field. This is where all the diverse components that make up the GIS are brought together for the first time. Even if it were possible to fully assemble the GIS in a factory, it would still have to be disassembled for transportation, shipped, and then reassembled at the installation site.The objective of the field tests is to confirm that
