the siprotec 7sj66 unit is a numerical protection, control, and monitoring device. Siprotec 7sj66 is featuring the "flexible protection functions". Up to 20 protection functions can be added according to individual requirements. Thus, for example, a rate-of-frequency-change protection or reverse power protection can be implemented.the relay provides control of the circuit-breaker, further switching devices and automation functions. The integrated graphical logic editor (cfc) allows the user to implement its own functions, e. G. For the automation of switchgear (interlocking). The communication interfaces support the easy integration into modern communication networks. protection functions overcurrent protection directional overcurrent protection sensitive directional ground-fault detection displacement voltage intermittent ground-fault protection directional intermittent ground fault protect high-impedance restricted ground fault inrush restraint motor protection overload protection temperature monitoring under-/overvoltage protection under-/overfrequency protection rate-of-frequency-change protection power protection (e.g. Reverse, factor) undervoltage controlled reactive power protection breaker failure protection negative-sequence protection phase-sequence monitoring synchro-check fault locator lockout auto-reclosure control functions/programmable logic commands for control of cb and of isolators graphical visualization of switch positions control via keyboard, binary inputs, digsi 4 or scada system user-defined logic with cfc (e.g. Interlocking) monitoring functions operational measured values v, i, f energy metering values wp,wq circuit-breaker wear monitoring slave pointer trip circuit supervision fuse failure monitor 8 oscillographic fault records motor statistics languages english, spanish, russian, polish and turkish communication interfaces system interface protocols: iec 60870-5-103, iec 61850, modbus rtu, dnp3 electrical and optical interface rstp (redundancy protocol for ethernet) service interface for digsi 4 or rtd-box front usb interface for digsi 4 time synchronization via irig b, dcf77 hardware spring-type terminals 4 current transformers 4 voltage transformers 16/22/36 binary inputs 7/10/23 output relays graphic or 8 line display
