SF6 Circuit Breaker Testing and Maintenance
When a pole on a circuit breaker with SF6 gas fails to clear, the cause can be external, such as the spring assembly, insulation, or resistance. The cause can also be internal. To assess the internal cause, SF6 Gas Analysis is done to assess signs of internal component failure.
Testing your SF6 gas on a routine basis is part of NETA’s recommended maintenance practice. It is an early warning sign that helps set priorities before they become emergencies. Keeping up on routine maintenance can save you from downtime, costly repairs, and unnecessary emergencies. UIS Technicians are trained to collect the component and report on the gas condition.
