Matalajännitteisestä

Matalajännitteisestä is Finnish grammatical form (elative/genitive singular) of the adjective matalajännitteinen, meaning related to low voltage. The base term matalajännitteinen is used to describe electrical equipment, systems or conditions operating at relatively low electrical potential. The elative form is used to express origin, source or context, as in “matalajännitteisestä järjestelmästä.”

Terminologia: matalajännitteinen describes voltages considered less hazardous than high voltage. International standards generally define low voltage as up to about 1000 V alternating current (AC) or 1500 V direct current (DC); national provisions may vary. In Finnish language, matalajännitteinen is applied to devices, installations and networks designed for such voltages, for example “matalajännitteinen jakeluverkko” or “matalajännitteinen laite.”

Käyttö ja turvallisuus: While low voltage reduces risk compared with high voltage, it still presents hazards. Design and operation emphasize insulation, protective enclosures, grounding, and proper protection devices. Safety standards such as IEC 60364 and EU directives influence Finnish practice. The term also appears in everyday contexts, to distinguish consumer electronics and household electrical installations from high-voltage industrial systems. The elative form “matalajännitteisestä” is typically used in phrases denoting source or relation, e.g., “matalajännitteisestä jännitteestä johtuva vika.”
