2020-10-23GIS is a kind of metal enclosed switchgear. That means, all the equipments of the electrical switchgear are enclosed by gas tight metal enclosure and SF 6 gas is used as insulation between live parts of the equipments and earthed metal enclosure. This type of switchgear, means, and gas insulated switchgear is

Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product

Assessment of Sulphur Hexafluoride (SF6) gas insulation. Testing SF 6 gas for impurities will therefore indicate potential issues with the switchgear.. Decomposition products arise during operation of SF 6 gas-insulated switchgear through arcing in moist or impure SF 6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear.

2020-1-8Leak testing is of paramount importance to ensure safe operation of the switchgear during its lifetime. Vacuum switchgear must maintain their vacuum in order to prevent arcing within the switch. Likewise gas insulated switchgear must maintain their pressure level to prevent arcing when the contacts open.

2021-1-20Gas-filled compartments cannot be opened, as they would then lose their functionality. Nevertheless, gas-insulated switchgear systems also receive a classification. Key to table 5.1.3 LSC2: On access to the cable terminations of a panel, the busbar and all other panels can remain energized. Note from IEC 62271-200:

2019-9-17The leak-rate test (MAC test):This test is based on the Penning Discharge Principle which is named after Frans Michael Penning (1894-1953). Penning showed that when a high voltage is applied to open contacts in a gas and the contact structure is surrounded with a magnetic field, the amount of current flow
