SF6-Air Grid Solutions for testing

This involved testing the individual processes, first with nitrogen, and then with carbon dioxide before final extensive testing using sf 6 went ahead. These tests allowed the process parameter models to be refined, and also proved that the technology is capable of separating out contaminants from sf6-gas.

  • Air insulated switchgear | SF₆-free | Eaton

    SF 6 or sulfur hexafluoride is a colorless, odorless, synthetic gas. It has a profound chemical robustness that protects it from reaction. Its high dielectric strength, which increases further under pressure, makes it an excellent electrical insulator.

    This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class SF6 dead tank breaker, two to three exposures per phase are required to provide adequate data. For this breaker size, Siemens can typically complete inspections on one to two breakers per day. Slide 1 of 1
