The invention relates to a sectioning device for separating or connecting two parts of a three-phase electric circuit, intended to be positioned in an enclosure of a GIS substation.

Alstom Grid will manufacture the GIS equipment in France and Switzerland.

Rehabilitation of one 132/33 kV, 3 x 63 MVA GIS substation and three 132/33/11 kV AIS substations

AREVA T&D will deliver a 400/132-kV GIS substation, which will strengthen power supply for the fast-growing Northern Emirates region.

The existing 220-kilovolt (kV) air-insulated switchgear (AIS) substation will be replaced by a compact 380 kV GIS substation, increasing transmission capacity and flexibility.

The embedded GIS system includes a GIS engine and a electronic map database.

Since 2010, GIS AG is managed by our CEO, Ivan Muri, who was in charge of the development for several years previously.

Ivan Muri, who previously was the development manager at GIS, is promoted to the position of CEO on January 1, 2010.

A method for simulating very fast transient overvoltage（VFTO）generation in a gas insulated switchgear (GIS) transformer substation and a test loop thereof are provided.
