C.16 Option 28: Power System Time, Frequency and Phase Monitor 165
Set Voltage Amplitude Correction
Command: v:kRV
“v:kRV” sets the system voltage amplitude correction.
Response:
C
Where: v = Voltage correction per unit with 1.000000 equal to no correction.
k = Security Key (e.g. 1084)
Return Time, Frequency, Phase Deviation with UTC Time
Command: nPD
“nPD” returns the System Time, Frequency and Phase Deviation with a UTC time reference, at
each issuance of the command.
Response:
(when n = 0) mm/dd/yyyy hh:mm:ssU ss +f.fff +t.tttt ppp.ppp vvv.vv
C
(when n = 1) mm/dd/yyyy hh:mm:ssL ss +f.fff +t.tttt ppp.ppp vvv.vv
C
Where:
mm/dd/yyyy = Date
hh:mm:ssU = Time of Day, UTC
(or)
hh:mm:ssL = Time of Day, Local
ss = Status (0 = Locked, 1 = Unlocked)
(first character is Reference Status:)
(second character is clock status per IEEE 1344)
+f.fff signed Frequency Error in Hz.
+t.tttt signed Time Deviation in seconds.
ppp.pp Phase Angle, 0 to 360 degrees.
vvv.vv Line voltage, rms Volts.
