integrity period can be dynamically configured by IEC client. (The Shark® 200
meter does not support Goose nor Journals.)
• The node LPHD1 defines physical parameters such as vendor, serial number,
device name plate and the software revision number.
• The node "nsMMXU1" contains the "normal-speed" basic electrical measurements
such as Volts / Amps / Watts / VARs / Frequency / Power Factor / etc. The elec-
trical measurements are data objects in hierarchical structure as per the IEC
61850 specifications.
For example, Phase A voltage:
• which is in the object "PhV"
• which is of type "WYE_ABC_mag_noDC"
• which in turn has the object "phsA"
• which again has an attribute named "instVal" to represent instantaneous
values, and also the "mag" attribute, which represents the magnitude as
an analog magnitude, with the attribute "f" to get the value in 32-bit
floating point.
Thus the voltage of phase A, would be referred in this nested structure as
"Meas/nsMMXU1.PhV.phsA.instVal.mag.f".
• The node "nsMHAI1" groups together the THD per phase measurements taken at
normal speed.
Following the previous example, the THD for phase A would be referred as
"Meas/nsMHAI1.ThdPhV.phsA.instCVal.mag.f".
• The node "eneMMTR1" groups together all measurements related to energy
counters, like +/- Watt;hours, +/- VAr-hours and Total VA-hours.
• The nodes "setTCTR1", "setTCTR2", "setTCTR3" and "setTCTR4" contain the ratio
of the current used by the measuring device, for phases A,B,C and Neutral,
respectively. In this way, the user can take the IEC measurements (primary)
and convert them to Secondary using the ratios contained in these nodes.
