The Pro-N protective relays, thanks to the innovative performance concerning the digital signal processing, can be combined with different types of sensor size :

  • StandardCTs &¬† VTs
  • ThySensor
  • Low power Current Transformers (LPCT)

The NA60 protection relay, in conjunction with the new sensors combined ThySensor, can be used in all applications for the
measures with traditional CTs and VTs with significant user benefits:

  • Current, voltage, voltage-indicator lamp voltage and insulator in the same component
  • Low size and low weight; installation inside limited size MV switchgears is possible, thereby improving maintenance
  • Galvanic insulation for current and voltage measurements
  • Being a single model suitable for measuring electrical quantities of a wide range of applications, inventory management is optimized
  • Absence of saturation and ferroresonance phenomena
  • High measurement accuracy.
