The SIPROTEC 4 7SA6 distance protection relay is a universal relay for protection, control and automation with a 4-line displayon 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)
