2.3.2.2 Currents
Permanently installed 1 A or 5 A CT’s, or clamp-on CT’s interface directly to the
galvanically isolated current inputs.
The instrument calculates the “missing current” by assuming the sum of all currents
is zero. (Please refer to Section 2.4.5 for more info)
Alternatively, 1 VRMS voltage output current transducers or Rogowski coils with 5 VDC
power supply can be used to measure current.
Current to voltage transducers can interface directly to 4 low voltage differential
inputs. (Please refer to Section 2.4.6 for more info)
2.3.3 Power sources
The instrument is powered from a power factor corrected AC supply input (90–300 V
AC/DC).
It can also be powered from an IEEE 802.3-2008 compliant PoE Plus (< 12 W) source.
The internal LiFePO4battery powers the instrument in the absence of power. This
battery guarantees 2,000 charge/discharge cycles. If cycled once per day, it translates
to at least a 5-year useful life.
Please refer to Section 2.4.3 for more detail.
2.3.4 Communication
Two (2) Gigabyte Ethernet ports facilitate local and networked external
communication. One port is used to interface with corporate networks (DHCP or
fixed IP support). The second Ethernet port is used to create a local network by
means of being a local DHCP server. Please refer to Section 2.4.10 for more detail.
The Vecto III supports WIFI communication. Please refer to Section 2.4.12 for more
detail. The Vecto III has an optional built-in cellular modem. Please refer to Section
2.4.13 for more information.
The remote support software supports automatic service discovery protocols.
Laptops, when connected to the Vecto III, will receive an IP from the instrument. The
remote support software can automatically discover which instruments are
connected to the local network. Please refer to the Osprey LiteTM user manual for
more information.

2.3.5 Osprey Pro (Enterprise Support)
When connected, each instrument automatically establishes a permanent secure
communication link to a corporate server (local or internet based). An instrument
management system (IMS) keeps track of each instrument’s location, configuration,
health (telemetry) and PQ data recorded.
Downloading of data is automated and recorded data can be accessed via the
Internet in graphical, tabled and report form as and when it becomes available. Raw
data can be analysed in Osprey LiteTM or exported for further analysis in for example
Microsoft ExcelTM or MatlabTM.
Osprey LiteTM simplify the analysis of waveform events such as dips and swells by the
time-aggregation of multiple waveform events to single network incidents.
Osprey LiteTM classify and report on recorded data according to industry standards
such as NRS048, EN50160 and IEE1158. All communications are encrypted and each
instrument is password protected. More information can be obtained at
ospreypro.com.
2.3.6 Sampling Rate
The instrument samples all analog input signals at a rate of 500 kHz (10 000 samples
per cycle) and then digitally down-sample the data to 50 kHz (1000 samples per
cycle). All IEC 610000-4-30 parameters are calculated based on this 50 kHz resolution
for both voltage and current.
Waveform and other events are triggered from the 500 kHz digitised waveforms.
These waveforms are locked to the fundamental frequency to prevent multiple zero
crosses.
Captured waveform data can be further subsampled to reduce stored data size. The
user can configure the waveform-sampling rate from 1 kHz to 50 kHz.
Please refer to the Osprey LiteTM user manual for more information on selecting the
down-sampling rate.
2.3.7 The 1/6th Sense
The Vecto III calculates a complete set of 1-cycle sliding RMS and fundamental
phasor parameters on each of the 3 voltage phases resulting in a resolution of 6
values per cycle per phase. The IEC 61000-4-30 Class A requirements are based on a
½ cycle sliding approach. This higher resolution data improves the detail of the event
profile and enable more accurate depth/duration calculations.

Please refer to the Osprey LiteTM user manual for more information on 1/6th cycle
data.
2.3.8 Event Recording
Users can customise the recording of an event. The IEC 610000-4-30 definition of for
example a dip event, can be changed to improve the understanding of phenomena of
concern.
Upper and/or lower thresholds to define an event can be set by the user based on
waveform, 1/6th sense, 10/12-cycle block and aggregated parameters.
Single-phase and multiple-phase triggers can be defined.
When a threshold is exceeded, the Vecto III will retain pre- and post-diagnostic
information of the event.
Please refer to the Osprey Lite user manual for more information on event
recordings.
2.3.9 10/12-Cycle Block Recording
The Vecto III records all RMS and harmonic data from each 10/12-cycle block
(≈200ms block) for both voltage and current as prescribed the Class A performance
requirements of the IEC 61000-4-30, edition 3.
These block values contain both amplitude and angle information of all voltage and
current harmonic components up to the 63th harmonic order.
Each block is time-stamped with a 20 s time resolution and within a 1 s time
uncertainty

2.3.10 Variable time interval trends
10/12-Cycle block RMS and harmonic parameters are aggregated according to IEC
61000-4-30 requirements over a user-defined time interval (1 to 30 minutes).
Clock synchronised parameters are time-stamped with a 1 second time resolution.
2.3.11 Synchrophasors
The Vecto III is also a phasor measurement recorder. Recording of 50 Hz (or 60 Hz)
synchrophasors can be activated in the configuration setup.
