MountingWall Mounting,Panel mounting

The 7SR11 series of relays provide overcurrent and earth fault protection. These relays are typically applied to provide the main protection on feeders and interconnectors and the backup protection on items of plant such as transformers. On distribution system circuits overcurrent and earth fault protection are often the only protection installed.

Features

The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protection.

 

The relays are available in single and four pole variants housed in E4 cases with the IEC 61850 protocol option housed in an E6 case. Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue inputs and binary input/output circuits.

 

Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection or rear electrical RS485 port for remote connection is provided.

7xt34 20 Hz Band Pass For 100 % Stator Ground Fault Protecti

Device with a 20 Hz band pass. It smoothes the square wave voltage of the 20 Hz generator (7XT33) and protects it against ground faults with maximum displacement voltage. At 20 Hz the series resistor is 8 and at rated frequency (50/60 Hz) it is more than 100 . Moreover, the device features a voltage divider for reducing the measured displacement voltage (division ratio 5:2 or 5:1) at a grounding transformer or neutral-point transformer. The external divider 3PP1336-1CZ is not applicable

The operating and parameterization program Reydisp is the basic software used for the configuration of the Reyrolle range of protection relays. It provides a user-friendly tool with the built-in tutorial, help file, and manual which reduces the requirement for additional training. This intuitive software allows the viewing and editing of settings, viewing fault information, configuring the relays language, IDMT curves, and communication data points.

When configuring Reyrolle devices with the optional IEC 61850 Ethernet communication ports the Reydisp Manager PC software should be used. This software provides the additional configuration tools to ensure an efficient 61850 engineering process.

The Reydisp Manager can also be used with the latest releases of the 7SR210 and 7SR220 devices.

Reydisp Evolution and Reydisp Manager are free of charge and can be downloaded directly from this site. The PC-program works with common Windows operating systems incl. Windows XP.

Reydisp Evolution is a Windows based suite of software tools, providing the means for the user to fully configure the relay and is common to the entire range of Reyrolle protection relays.

 The setting configuration tool allows the user to apply settings, interrogate settings and retrieve events and disturbance waveforms from the device.

The Language Editor software gives the user the ability to customize the text displayed in the relays, Menu structure, and instrumentation views.

The tool allows a language file to be created and transferred to the relay containing any Western European characters.To facilitate easier interfacing to a substation the relays default Protocol configuration may be modified using the communication editor software tool. The communication editor is a PC-based software package provided within the Reydisp suite which allows modification of the data points available from the relays associated with the IEC 60870-5-103, DNP 3.0 and MODBUS Protocols.

The Curve Editor software allows the creation of IDMTL curves for Reyrolle relays, to allow the user to have more flexibility when grading with other devices. It can import existing curves, create new curves from templates and send the curves to the relay.

Further Features:

  • Configuring device settings
  • Create and edit logic diagrams
  • Configure time zones
  • Firmware upload
  • Configuration upload

A copy of Reydisp Evolution is also embedded in the tool for ease of use.

All of the software tools contain the basic tools for saving, printing data and opening template files.
