Web1.Introduction. High-voltage switchgear is a widely used electric energy distribution equipment in power systems. However, condensation often occurs on the surface of the insulation equipment inside the switchgear due to the 1) accumulation of water in the cable trench, 2) poor sealing of the switchgear and, 3) existence of dehumidification blind areas. WebTAW ® Custom Equipment developed Technical Field Services in the mid-1990s, to test CE-built switchgear before it was released to customers. At the time, the group, known as TFS, also helped with equipment field installations. TFS quickly evolved from installing and servicing TAW switchgear to working on all of TAW customers’ switchgear.
