Fire detection and alarm systems - NBS National BIM Library detection and alarm systems (105) Fire detection and alarm systems consist of control and indicating equipment, detection devices, manual call points, and visual/ audible alarms.
Field drying of transformer insulation - Siemens USA oil also passes through a vacuum chamber where gas and moisture is removed. While maintaining vacuum on the transformer tank, the oil is then removed, exposing the solid insulation surface(s) to deep vacuum. During this period that can be from 12-48 hours, the combination of temperature and vacuum causes the moisture in the insulation to boil.
