Features :

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)
