Flammable gas found in the relay indicates some internal fault such as overheating or arcing, whereas air found in the relay may only indicate low oil level or a leak.
On a slow accumulation of gas, due perhaps to slight overload, gas produced by decomposition of insulating oil accumulates in the top of the relay and forces the oil level down.
在气体慢积累模式中，可能由于轻微过在，绝缘油分解产生的气体在继电器的顶部聚集，迫使油位下降。

SQL Relay has the potential to consolidate and streamline typical architectures involved in application development for oil-and-gas operations.
