Electrical Protection And Switch Gear Training

Product Details:

Device with wire-wound resistors as voltage dividers (division ratio 10:1 or 20:1) to inject the excitation voltage into the underexcitation protection in the SIPROTEC 7UM62.

Product Details:

Resistor unit with 4 x 20 k resistors to connect the 1-3 Hz rotor ground fault protection in the SIPROTEC 7UM62.

Product Details:

We conduct the training on Electrical Protection Schemes such as Distance Protection, Differential protection, Bus Bar Protection, REF Protection, Generator Protection scheme etc. on site or in our office. With only 3 models that can protect motors from 1/4HP to 300H/P from Overload, Single Phasing and Locked rotor, you can relax in peace whilst this workhorse will continue to do its designated role – Protect your 3 phase motor

Features:

• Compact Design with 2 Integral CT’s (Current Transformers)
• Multiple protections – Overload, Single phasing & Locked Rotor
• Wide adjustment range results in drastic reduction of inventory

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

Product Details:

7XT71 controller unit used conjointly with the 7XR6004 for the 1-3 Hz rotor ground fault protection in the SIPROTEC 7UM62. A low-frequency square wave voltage of approx. +/- 50 V is injected into the rotor circuit. An AC voltage or a DC voltage can be used as supply voltage.

Product Details:

Coupling unit for the rotor ground fault protection with 50 Hz/60 Hz injection in the SIPROTEC 7UM6. A 3PP1336-0DZ is required additionally.

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.

Product Details:

20 Hz generator for the generation of a square wave voltage of approx. 26 V. The maximum power consumption is < 100 VA.
The 20 Hz generator is required for the 100% stator ground fault protection in the SIPROTEC 7UM62. An AC voltage or a DC voltage can be used as supply voltage.
