What is included in an insulating gas analysis on a SF6 switch according to NETA-ATS?

In the context of insulating gas analysis on a sulfur hexafluoride (SF6) switch, moisture tension is a crucial factor. SF6 is a gas used for its excellent insulating properties, and moisture content can significantly affect its performance. High moisture levels can lead to reduced dielectric strength, increasing the risk of electrical breakdown and equipment failure.

Moisture tension refers to the amount of water vapor present within the gas, which must be monitored closely. By assessing moisture tension, technicians can determine whether the insulating gas is within acceptable limits for safe operation. Controlling moisture levels is essential not just for prolonging the lifespan of the equipment but also for ensuring the overall reliability and safety of the electrical system.

While dielectric strength and gas pressure are also important parameters for assessing the condition and performance of SF6 gas, moisture tension is particularly critical as it directly impacts the insulating properties of the gas. Voltage regulation, in this case, does not relate directly to the insulating gas analysis.
