Relays
are
the
“brains”
of
the
electrical
distribution
system.
If
an
abnormality
occurs
on
your
system,
they
keep
the
damage
to a
minimum,
helping
to
reduce
your
downtime
and
protect
your
people.
But,
if
your
relays
aren’t
working
properly,
watch
out.
An
overload
or
short
circuit
could
result
in a
long,
costly
outage
and
extensive
equipment
damage.
The
only
way
to
be
sure
that
your
protective
relays
are
up
to
the
job
they’re
intended
to
do
is
to
put
them
through
a
regular
program
of
inspection,
cleaning
and
calibration.
You
also
need
to
be
sure
that
relay
settings
are
strategically
selected
and
coordinated,
to
help
minimize
how
much
of
your
plant
is
affected
by
an
overload
or
short
circuit.
HVM
can
provide
these
services,
including
creating
and
updating
your
single-line
diagrams
and
short
circuit
and
coordination
studies
to
assure
proper
settings
and
coordination.
Replacing
electromechanical
(EM)
relays
is
the
fast,
low-cost
way
to
get
the
advantages
of
digital
relays
without
the
expense
of
new
switchgear.
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, Mulhlin,
GE,
Baster,
and
many
others
will
improve
system
reliability,
safety,
and
allow
for
more
flexible
communication
delivery
within
your
facility.
