Relay Design and Integration

Replacing electromechanical (EM) relays is the fast, low-cost way to get the advantages of digital relays without the expense of new switchgear. Add the benefit of self-testing, I/O, improved control, event reports, and fault identification to your existing switchgear. Digital relays provide the system information you need to improve protection, reliability, efficiency, and overall system performance. One digital relay can replace an entire rack of EM relays for a fraction of the price and improve all areas of performance. Upgrading to a digital relay makes use of existing CTs, breakers, and most wiring, but still enables all the advantages of a fully digital solution. Built-in communications protocols make data available anywhere on your system. Digital relays perform thousands of self-tests every minute and eliminate the manual testing and calibration needed for EM relays. Join the thousands of utility, industrial, and commercial users that have made the jump to digital.

Let Emerson help you design a new system or integrate an existing system and start reaping the benefits of digital technology today.

Benefits

 

  • Digital relays save space. One digital relay can replace multiple electromechanical models.
  • Digital relays offer fault location, time-tagged event reports, fault diagnosis, data recording, and communication
  • In most cases, digital relays cost less than EM relays
  • By replacing scheduled maintenance with predictive maintenance, digital relays pay off in as little as two years. Retrofitting offers a quick payback.
  • Improves safety by determining digital relays’ status remotely instead of making a trip to the field and adding arc-flash protection.
  • Digital protective relays are an integral aspect of a smart grid. Use them as the building blocks for a smarter system.
  • Fit new protective relays into your existing cutouts
  • New construction deferred because of budget constraints? Use resources to upgrade and retrofit existing switchgear.
  • Digital relays provide an excellent source of information for asset management.
Scope

 

Emerson can help you design and implement upgrades and replacement of your aging protection based relay components.  Digital relay upgrades, such as those from Schweitzer Engineering Laboratories, Mutilin, GE, Basler, and others will improve system reliability, safety, and allow for more flexible communication delivery within your facility.
