Peak voltage(Secondary side value)
Unbalance factor of Voltage and current
Example:Read A phase Voltage wave peak coefficient,communication reading value “Val_t” is 1414
at address 0×0119,then Val_s ＝Val_t / 1000＝1414/1000＝1.414
7.5.4Voltage/current harmonic data
This series measuring value is read out by Modbus-RTU protocol 0×03 command,each item occupy
one word.Relation between communication value and actual value is shown as below：Val_s＝（Val_t /
100）%
Example:Read current third harmonics containing rate of phase A current,communication reading
value “Val_t” is 157 ,at address 0×01D0,then Val_s ＝(Val_t/100）%=1.57%
7.5.5Time
This series measuring value includeyear,month,day,hour,minute,second,is read out by Modbus -RTU
protocol 0×03 command,each item occupy one word,adopt BCD code format.
Example: Read the number of years, MODSCAN in HEX reading mode can be read directly in
the address bar 0X0081
7.5.6Event record
Event record 1- Event record 16 are recorded in chronological order, Event record 1 contains the
data of latest event, Event record 16 contains the data of earliest event.The data format is as
follows
Bit 0(The lowest bit):0 is DO,1 is DI
Bit 7(The highest bit):0 is
disconnected,1 is closed
Serial number of switching capacity
0 is first,1 is second and so on
Value of the alarm(the smallest is recorded when it is open-phase)
Note:0-Over line voltage、2-Over frequency、3-Under frequency、4-Under power、5-Over power、6-Over
current、7-Under power factor、8-Over voltage unbalance、9-Over current unbalance.
Example:DO1 is alarm of A phase voltage , under voltage alarm occurs in 15 January 22nd
