Punime nën tension - Dedektorët e tensionit - Pjesa 3: Dedektorët e tipit me dy pole për tension të ulet

Live working - Voltage detectors - Part 3: Two-pole low-voltage type

Scope

Is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1500 V d.c and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 V d.c.; voltage class B: up to and including 1 000 V a.c./ 1 500 V d.c. Low-voltage detectors covered by this standard are not intended to provide measurement of absolute values. Measuring devices are excluded form this standard. NOTE - The requirements for measuring devices are specified in EN 61010-1 and EN 61010-2-031.
