Preventive maintenance - Hitachi ABB Power Grids organic products in a transformer degrade over time and finally they lose the capability to withstand the stresses a transformer might see in daily life (short circuits, energizing, vibration, etc.). It is possible to reverse the ageing of mineral oil through oil reclamation that can restore the material properties close to the values when new.

TechTopics No. 101 | TechTopics | USA - Siemens Global construction of the Siemens type 8DA and type 8DB gas-insulated switchgear makes the likelihood of a short-circuit fault or an arcing fault inside the switchgear extremely low, far, far lower than in air-insulated switchgear. For this reason, use of bus differential protection with gas-insulated switchgear is considered unnecessary.
