46、 kV a.c. andfrequencies from 50 Hz to 60 Hz.This standard is applicable to two-pole phase comparators having a connecting lead betweenthem, two-pole phase comparators operating with a wireless connection and single-pole phasecomparators operating with a memory system.This standard is applicable to p
47、hase comparators used in contact with the part to be tested,as a single unit or as a separate device completed by an adaptable insulating pole coveredin IEC 60855 or IEC 61235.Some restrictions on their use are applicable in the case of factory-assembled switchgear andon overhead systems of electrif
48、ied railways (see annex B).Devices which can be used as voltage detector and phase comparator are not covered by thisstandard.NOTE Except when otherwise specified, all the voltages defined in this standard refer to phase-to-phase voltagesof three-phase systems. Phase comparators may be used in other
49、 than three-phase systems, but the applicablephase-to-phase or phase-to-earth (ground) voltage must be used to determine the operating voltage.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this International Standard.
