Product Description

The SIPROTEC 7SA64 distance protection relay is a universal relay for protection, control and automation with a graphic display on the basis of the SIPROTEC 4 system. Its high level of flexibility makes it suitable to be implemented at all voltage levels. With this relay you are ideally equipped for the future: it offers security of investment and also saves on operating costs. High-speed tripping time

  • Impedance setting range allows very small settings for the protection of very short lines
  • Self-setting detection for power swing frequencies up to 7 Hz
  • Current transformer saturation detector prevents non-selective tripping by distance protection in the event of CT saturation.
  • Phase-segregated teleprotection for improved selectivity and availability
  • Digital relay-to-relay communication by means of an integrated serial protection data interface
  • Adaptive auto-reclosure (ADT)

Protection Functions

  • Non-switched distance protection with 6 measuring systems (21/21N)
  • High resistance earth-fault protection for single and three-phase tripping (50N, 51N, 67N)
  • Earth-fault detection in isolated and resonant-earthed networks
  • Tele (pilot) protection (85)
  • Fault locator (FL)
  • Power-swing detection/tripping (68/68T)
  • Phase-overcurrent protection (50/51)
