FUNCTIONS

paralleling device siprotec 7ve85 is specifically designed for the synchronization of generators (power plant units) with the power grid or synchronization of 2 electricity-supply systems.

the 1.5- and 2-channel synchronization function is the made function of the siprotec 7ve85. To warrant a high level of security and reliability, the software works with various monitoring functions. In addition, the most important hardware components are duplicated. Two different measuring algorithms are used in accordance with the multi-channel redundancy. This avoids overfunctions through systematic errors. At the same time, the different methods of measurement are applied and processed independently of each other with different memory areas. The high level of reliability and flexible options to adapt to the equipment requirements allow a wide variety of applications.

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.

the siprotec 7ut612 differential protection relay is used for fast and selective fault clearing of short-circuits in transformers of all voltage levels and also in rotating electric machines like motors and generators, for short lines and busbars. The protection relay can be parameterized for use with three-phase and single-phase transformers.the specific application can be chosen by parameterization. In this way, an optimal adaption of the relay to the protected object can be achieved.in addition to the differential function, a backup overcurrent protection for 1 winding/star point is integrated into the relay. Optionally, a low or high-impedance restricted earth fault protection, a negative sequence protection, and a breaker failure protection can be used. With external temperature monitoring boxes (thermo-boxes) temperatures can be measured and monitored in the relay.therefore, complete thermal monitoring of a transformer is possible, e.g. Hot-spot calculation of the oil temperature. The relays provide easy-to-use local control and automation functions. The integrated programmable logic (cfc) allows the users to implement their own functions, e.g. For the automation of switchgear (interlocking). User-defined messages can be generated as well.the flexible communication interfaces are open for modem communication architectures with the control system. The protection relay can be parameterized for use with three-phase and single-phase transformers.
