◎System
●Created data for motor protection : Voltage, Current/KW, Earth current,
Isulation resistance, Temperature, Power factor, Unbalance
●Building data base(DB) up based on 485/Modbus network
●Analyzing and managing DB DATA in order to check the motor condition and
to make alarm in case of unstable condition : able to preset alarm level for each factor
●Possible to analyze accurate trip cause through stored data of trip instant in
MWR-S(Motor working Recorder) connected with converter directly
●Office PC is able to do master job without installation for additional Server as master

Digital Motor Protection Relay
DigitalMotorProtectionRelay,DSPVIP-Series ,P-Series,C-Series,A-Series,
is useful forlowvoltagemotorprotection. It is aimed to protectamotoragainsta
troublewhich is happened fromover/underload[current],lockedrotor,stall[shock],voltage
(powertype)/currentunbalance,phase loss,reversephase, short circuit,
groundfault,over/undervoltage(powertype) in motoroperation.
Also it is able to raisethe efficiency formotoroperationas being possibleto realizea
supervision, aprotectionand acontrol,furthermoreeach kind of series itemtakesit's own
specialized function, respectively, in order to meet variouscustomerneed such
as short circuit,alarm beforetrip,4~20mA output forloadcurrent,insulation
resistancemeasureemnt,vibratedfrequencydetectionthrough4~20mA output from
sensor,RS485 or Ethernet communication.
EspeciallyCurrent-Resistancetype canmeet twokind of differentjob which is
consistedof powerfulmotorprotectionduring amotorrunning stateand the insulation
resistancemeasurementforapowerline of the motorduring amotorstopstate.This
wouldbe morepowerfulto preventan industrialdisastercausedby adegradedpower
line of the motorused forthe longtermsincefirstinstallation
Nowwe launch newitemsuch as DSP-2SD/3SD which is based on 2CTor 3CTwith
basic essentialprotectivefunction except GR fault matched with ZCT. However, we
prepared 3SD-RG with GR fault protection through residual circuit for user who
want to take specific function like GF. We will do not cease R&D to meet customer's
need in any conditionin todayand in future.
