Описание
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 IEC 61010-1 and IEC 61010-2-031.The contents of the corrigenda of May 2000 and December 2000 have been included in this copy.
