How Siemens Reyrolle 7SR105 Motor Protection Numerical Relays Can Help Your Power Grid

Siemens Reyrolle 7SR105

Power system networks have noticed exceptional growth over the last few years and so is the demand for power requirements since the last decade. Electrical Power System protection is necessary for the protection of the user as well as the system equipment from fault and also any other abnormal conditions. Protection is critical in the proper operation & control of power systems. The occurrence of faults is common in any electrical power system. A power system fault can be defined as any unwanted condition that occurs in the power system. These conditions include short circuits, over-current,  over-voltage ground short and current leakage. As the system is growing increasing loads, voltages and short-circuit duty in distribution systems,  current protection has become more important today.  To provide proper protection to our system we need a device that can monitor current, voltage, frequency etc.

Siemens Reyrolle 7SR105 motor protection relays are numerical protection devices intended for use in multiple motor protection applications. The relay provides a thoroughly comprehensive functional software package with various integral application functions that are aimed at reducing installation, wiring and engineering time. The Reyrolle 7SR105 devices are reliable and also compact motor protection relays in a non-draw-out case with 6BI or Os, Serial interface, and RTD inputs with dependable current-based motor protection algorithms making them the simplest and also most comprehensive motor protection relay.

These relays are housed in a 4U high, size 4 non-drawn-out case and they provide protection, instrumentation, monitoring and also metering with integrated input and output logic as well as data logging and fault reports. Communication access to these relays functionality is easy with the help of a front USB port for local PC connection and a rear electrical RS485 port for remote connection. A broad range of measured values can be viewed on the front LCD and remotely via the communications channel. The integrated control feature enables the safe operation of a motor and monitoring of its start and stops operations.
