The SIPROTEC 5 Bay Controller is a control and automation device with optional protection function. It is designed for use in all voltage levels from distribution to transmission. As a full member of the SIPROTEC 5 family, it allows the use of a large number of protection functions from the SIPROTEC library with identical parameters like in the protection devices. The modular hardware enables the user to integrate as many IO's as needed.Main function:Bay Controller for medium and high voltage switchgear. Integrated operator panel and key switches (optional). Powerful automation functionality, easily configurable with DIGSI. A large number of protection functions available.Inputs and outputs:-5 predefined standard variants with 4/4-current/voltage transformers,-11 to 75 binary inputs,-9 to 41 binary outputsHardware flexibility:Flexible adjustable HW IO-quantity within the scope of the SIPROTEC5 modular system. The use of a second row allows more than 400 in- and outputs.Width of housing:1/3 x 19 Inch - 2/1 x 19 Inch DIGSI 5 permits all functions to be configured and combined as required. FUNCTIONS Integrated bay controller with versatile protection function from medium to extra-high voltage Control of switching devices Synchrocheck and switchgear interlocking protection Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE) Up to 4 pluggable communication modules, usable for different and redundant protocols (IEC 61850,IEC 60870-5-103, IEC 60870-5-104, DNP3 serial and TCP, Modbus TCP, PROFINET IO) Redundancy protocols PRP and HSR Arc protection Cyber security in accordance with NERC CIP and BDWE Whitepaper requirements Graphical logic editor to create powerful automation functions in the device Optional overcurrent protection for all voltage levels with 3- pole tripping Also used in switchgear with breaker-and-a-half configuration Overcurrent protection also configurable as emergency function Selective protection of overhead lines and cables with single-ended and multi-ended feeders using protection communication Secure serial protection data communication, also over great distances and all available physical media (fiber-optic cable, 2-wire connections and communication Networks) Capturing operational measured variables and protection function measured values to evaluate the plant state, to support commissioning, and to analyze faults Phasor Measurment Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol integrated Powerful fault recording (buffer for a max. record time of 80 s at 8 kHz or 320 s at 2 kHz) Auxiliary functions for simple tests and commissioning Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system
Breaker Management Protective Relay

The SIPROTEC 4 breaker management relay 7VK61 is a highly flexible autorecloser, synchro-check, and circuit breaker failure protection unit. This unit is used for the single and three pole auto-reclosure of a circuit-breaker after this circuit breaker has tripped due to a fault.The synchro-check function ensures that the two circuits being reconnected by closing the circuit-breaker are within a defined safe operating state before the CLOSE command is issued.The 7VK61 is also applicable as circuit breaker failure protection. A breaker failure occurs when the circuit-breaker fails to correctly open and clear the fault after single or three-pole trip commands have been issued by the protection.It is then necessary to trip the relevant busbar zone (section) to ensure fault clearance. Together with the above-mentioned protection functions, the following additional functions of the 7VK61 can be applied: end-fault protection, pole-discrepancy protection, overvoltage protection and under voltage protection. As a member of the numerical SIPROTEC 4 relay family, it also provides control and monitoring functions and therefore supports the user with regard to a cost-effective power system management.
