| Abstract |
Is applicable to portable phase comparators with or without a built-in power source to be used on electrical systems for voltages from 1 kV to 36 kV a.c. and frequencies from 50 Hz to 60 Hz.
This standard is applicable to two-pole phase comparators having a connecting lead between them, two-pole phase comparators operating with a wireless connection and single-pole phase comparators operating with a memory system.
This standard is applicable to phase 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 covered in IEC 60855 or IEC 61235.
