SF6-Air for testing

Hal ini terkait dengan tingkat kelembaban gas SF6, yaitu berapa banyak partikel air yang terkandung dalam isolasi gas SF6. Semakin tinggi nilai dew point maka dapat menurunkan nilai isolasi gas SF6 karena kontaminasi kelembaban air (CIGRE 15/23-1 Diagnostic Methods for GIS Insulating System, 1992).

  • The Importance of SF6 Circuit Breaker Testing and

    The SF6 is what helps cut off the power when there’s an overload. An SF6 Circuit Breaker also boasts a very high level of electro-negativity, which means it also has a high absorption capacity for free electrons. When these electrons collide with the SF6 molecules, they get absorbed immediately and turned into negative ions,
