Relay Protection and Control Device Quotation

Fiber and communications infrastructure knowledge brief Published 14 Sep 2023

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Relay protection and control devices are available from leading manufacturers like ABB, Siemens, DEIF, and Eaton, with online platforms and engineering tools to request quotations and configure devices to your system requirements. Available Devices and ManufacturersABB offers a wide range of digital and numerical relays suitable for medium- and high-voltage applications. Their relays are multifunctional, programmable, and can be ordered through the ABB Relays-Online platform, which allows you to select, configure, and track your order globally.

Siemens SIPROTE

C relays provide modular solutions for feeders, lines, motors, transformers, and generators.

The SIPROTE

C 5 and SIPROTEC 7 series include universal protection relays, differential relays for multi-winding transformers, generator protection relays, and busbar protection devices. Siemens' DIGSI 5 software enables full engineering control, configuration, and tailored functionality, allowing you to pay only for the features you need.

DEI

F offers the MVR-200 series, which integrates protection, monitoring, and diagnostics for busbars, feeders, generators, motors, and transformers. These relays provide under- and over-voltage protection, single-phase measurement, and advanced communication capabilities. Eaton provides digital protection relays including Arc Flash Relays, Bus Differential Relays, and Distribution Relays.

Eaton relays combine metering, protection, and control in compact designs, reducing panel space and wiring costs. Their relays are suitable for high-impedance differential protection schemes and general distribution system protection. How to Request a QuotationIdentify the Device Type: Determine whether you need feeder, busbar, transformer, generator, or motor protection.

Consider voltage level, system configuration, and required functionalities. Use Manufacturer Platforms: ABB: Use Relays-Online to configure and request a quote. Siemens: Use the SIPROTEC product selector and DIGSI 5 software to identify suitable relays and request pricing.

DEI

F and Eaton: Contact local sales representatives or use online inquiry forms to request quotations. Provide System Details: Include voltage levels, load ratings, protection requirements, and any communication or monitoring needs to ensure accurate pricing and configuration. Compare Options: Evaluate features, modularity, expandability, and compliance with standards (IEC 61850, ATEX, etc.) to select the most suitable device.

By following these steps, you can obtain a detailed quotation tailored to your protection and control requirements, ensuring compatibility with your electrical system and operational needs.
