Distance protection relay for all voltage levels



SIPROTEC 7SA64 Distance Protection

Perspective view

  • media title1

    The SIPROTEC 7SA6 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)
