Standards

IEC 61481-1

Application:

• Single-pole HV phase match checker.
• Maximum operating voltage: 36 kV.
  
  

Features:

• Single-pole device with C, K, W end-fitting.
• Storage of frequency and phase of distribution network voltages.
• Push-button test of the device, which also resets the memory.
• Class C: (maximum time for storing information in memory: 15 seconds when not connected to the line) . Non accordance (+110° to +250°)..
• LED indicators:
  • Orange (M) indicating the storage of a phase and the mains frequency;
  • Green (C) indicating that the mains phase is identical to the one previously stored (match); + dicontinuous beep buzzer.
  • Red (I) indicating that the phase of the network is of a different phase from that previously stored (mismatch) + continuous beep buzzer. 
• Voltage difference between the two networks to be compared: +/- 15%.
• Angle difference between the two phases (networks) to be compared: +/- 10°.
• The red ring indicates the physical limit to which the phase comparator can be inserted between live parts (57 cm from the red ring to the end fitting).
  
  

Composition :

• Option: Antenna Magnefix with a U Max utilisation : 18 kV, Ref C-921545.
