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