EN 61481:2001

EN 61481:2001 is a standard published by CLC. Its full title is "Live working - Portable phase comparators for use on voltages from 1 kV to 36 kV a.c.". This standard covers: 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 EN 60855 or EN 61235.
