Assessment of Sulphur Hexafluoride (SF6) gas insulation

Testing SF6 gas for impurities will therefore indicate potential issues with the switchgear.

Decomposition products arise during operation of SF6 gas-insulated switchgear through arcing in moist or impure SF6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear. In addition, while SF6 containers are designed to be gas-tight to ensure no environmentally hazardous SF6 gas escapes, it is important to monitor SF6 gas pressure both to ensure no leaks are present and also to ensure the switchgear is adequately insulated.
EA Technology is an accredited expert in all aspects of working with this valuable but potentially environmentally hazardous gas.

A typical survey would include:

The option is also available to take away a gas sample for laboratory chemical analysis.  This would provide a more detailed analysis of the gas content, providing additional information on any ongoing degradation of the equipment.

Test results will be provided in a written report with recommendations.
