Maintenance of switchgear and transformers

Humid ambient air is a problem for electrical systems. SZM ensures better air and a long transformer life by means of air absorbers.

A maintenance job took us to a quarry in the Harz mountains (Lower Saxony, Gemany) on a foggy day recently. For a construction company, we carried out maintenance and safety checks on the medium-voltage switchgear (Siemens and AEG) and checked the operational safety of the transformers.

In addition, we took oil samples in order to be able to precisely record the condition of the oil transformers with a Dissolved-Gas Analysis (DGA). Moreover, we installed our new adsorbers. These dry and purify the incoming air using valve technology by passing the air through a silica gel.

As a result, the transformers can now operate reliably for a long time and do not require shorter maintenance intervals because of the ambient conditions.
