Why is it important to test SF6 gas?

As part of preventative maintanence in most substations, measurement of humidity in SF6 gas should be completed. If the humidity content is within manufacturers’ specified limits, then the possibility of HF and SO2 creation is very low. If the humidity level is extreme, then those by-products will be created in high enough concentrations that corrosion will occur in the insulators, resulting in undesirable short-circuiting within the equipment.

SF6 purity has an effect on its efficiency in the circuit breaker. If the purity is exceptional, there is confidence in the effectiveness of the equipment.

With new equipment installations, a purity test can indicate if the circuit breaker was properly emptied prior to filling.
