Introduction
1. Overview
eMCM is
the
device
that
combines
current/voltage
signal a
na

technique
and
motor protection
technique. It
performs
motor protection
and diagnosis at
the
same

that it operates as

While existing motor protection relay just detects current status
of

,
eMCM
,
in
addition,
can
predict
and
monitor motor condition
so
that it
ensures the motor safety
and stable
motor management.
eMCM performs motor
condition monitoring
based on
the technology
developed in NASA and
it
needs minimum user intervention. Furthermore, eMCM provides energy
consumption measuring, which enables user
to
come up
w
i

h
an effective
plan
for dealing
with
efficient energy
consumption.
eMCM is
t
he
convergence device which is
able to deal with protection,
condition monitoring
and energy measuring of
the motor
in one
devi
c

.
