SF6-alternatives monitoringsolutions for middle voltages

2020-11-30At transmission voltages, the relatively low number of circuit-breakers means that a small specialist team can carry out maintenance on SF6 equipment. However, a completely different situation exists at distribution voltages. A city with fifty 132/11kV primary substations could have as many as 125,000 ring main units.
