Feeder Manager Relay

Three-phase Current, Voltage and Earth Fault multifunction relay for protection and management of MV/HV distribution lines. Real time measurement of the primary value of the input quantities are continuously available from relay's display and from the serial communication port. Relay's programming and setting can be made directly by the front face keyboard or via the serial communication ports. Setting, event recording and oscillography are stored into nonvolatile memory. The relay is fitted with a multivoltage, auto ranging power supply unit self protected and transformer isolated.

2. Three levels for Earth Fault independently programmable as directional or non directional
3. Selectable Time current curves according to IEC and IEEE standards
4. Two over/under voltage levels
5. Two over/under frequency levels
6. Zero sequence over voltage level
7. Two Negative Sequence current levels
8. One Positive Sequence over voltage level
9. One Negative Sequence under voltage level
10. Two Reactive Power (VAR) control levels (optional)
11. Trip circuit supervision
12. Associated Circuit Breaker control (OPEN /CLOSE)
13. Breaker failure protection
14. Output relays totally user programmable
15. Digital inputs user programmable
