EnergyPro Energy Analyser
Introduction
The EnergyPro represents leading edge technology in operator
interfaces. Data can be viewed in real time on the front panel, or for
more detail, PowerView software can be used to examine data
collected by the EnergyPro.
The EnergyPro:
▪Record RMS voltage, current, power (real and reactive), true
power factor, energy, THD, harmonics and three phase unbalance.
▪Has graphical display.
The EnergyPro is a 6 channel data logger. It monitors 3 phases of
voltage and current and calculates the neutral current.
A memory card interface is used to store recorded data on a
removable memory card. The EnergyPro will not begin a survey
without a memory card installed. Once a survey has been started the
memory card may not be removed until the survey has been stopped.

Firmware Features
Connection Check
Before a survey is started the user can set the voltage and current
connections from the hook-up screen (press the button). See
the Hook-Up Configuration section of this manual for more details.
RMS Data Storage
The EnergyPro stores RMS data at set intervals which can be
adjusted from 1 second to 30 minutes. The minimum, maximum and
average values are stored at the end of each storage interval. The
averaged values are calculated from the sum of the RMS values
(updated every second) over the preceding storage interval. The
minimum and maximum values are updated every second over the
storage interval.
Power Calculations
The power calculations are updated every second. The average
values of power are recorded. Power factor displayed is the true
power factor (not the displacement power factor) and is calculated as
the ratio of the real power (KW) divided by the apparent power (KVA).
Frequency
The system frequency is measured from the signal on V1 input and is
updated every second. The minimum, maximum and average values
are stored at the end of each storage interval.
Total Harmonic Distortion (THD)
THD is calculated as the ratio between the square root of the squared
sum of the harmonic magnitudes (for harmonics 2…16) divided by the
fundamental value. The THD calculations are updated every second.
The minimum, maximum and average values are stored at the end of
each storage interval. The individual harmonic information is stored
with the data and is available for viewing in software.
Three Phase Voltage and Current Unbalance
Unbalance is calculated as the ratio of the negative sequence
component divided by the positive sequence component. The
unbalance calculations are updated every second. The minimum,
maximum and average values are stored at the end of each storage
interval.

Energy Usage Display
The EnergyPro displays the total energy usage during the survey.
The total KWHR and the average KW/HR are displayed.
Logger Connection
Connection panel
The voltage and current connections are colour coded according to
individual phases.
Either clamp CT‟s or Flex CT may be used to monitor current.
The EnergyPro is powered from the voltage between V1 and V2
(between 115V and 600 Vac). If a single phase voltage is being
measured then V2 should be connected to neutral in order to receive
power from the measured voltage. The EnergyPro has an internal
battery that will supply power to the instrument when there is no
voltage between V1 and V2. The internal power supply will power the
instrument when V1-V2 is between 115V and 150V but will not charge
the battery. To charge the battery when the voltage is less than 150V
the EnergyPro must be turned off.
LED Indicators
Green Charging LED indicator
The Green Indicator will come on when the internal power supply is
operating.
Red Logging LED Indicator
This Red LED will flash when the logger is recording data.
Green Charged LED indicator
This Green LED will come on when the internal battery of the logger is
fully charged.

different connection types.

13
EnergyPro Energy Analyser
Logger Operation
1P2W
This is for a single phase circuit. The
EnergyPro assumes that V1 and
CT1 (and CT2, CT3 if used) are
connected to the same phase. The
1P2W mode allows the use of CT2
and CT3 for monitoring multiple
single phase loads. V2 is connected to neutral for the internal
power supply.
1P3W
This is for a split phase circuit.
Usually 120V from each line -
neutral and 240V from line - line.
3P3W
This is a three phase circuit that
does not have a neutral (delta
system). For direct connection the
voltages are connected. A-B (ch1)
and C-B (ch3) and the CTs are
connected to A (ch1) and C (ch3). Vca is calculated from the two
voltage measurement and Ibis calculated from the two current
measurements.
Note 1. V2 and neutral are both connected to Phase B. V2 is
connected for the internal power supply and neutral is connected for
measurement purposes.
Note 2. For direct connection in a delta system the 3P4W connection
can be used with the neutral connection floating or connected to
ground.
Note 3. If the voltage and current inputs are connected to external
CTs and PTs, then the external PTs must be connected A-B and C-B
and the external CTs connected to A and C. The EnergyPro should
be configured for 3P3W, V1 connected to A secondary, V3 connected
to C secondary, V2 and neutral connected to the PT secondary
common.
14 EnergyPro Energy Analyser
Logger Operation
3P4W
This is for a three phase circuit where
three voltages, line to neutral, and
three currents are measured. If a
neutral connection is not available the
neutral input may be left floating or connected to ground. Line –Line
voltage measurements are available on the EnergyPro front panel and
in software.
2.5E
Used when there are two voltage (line
–neutral) measurements and three
phase current measurements.
EnergyPro assumes that the two
voltage measured are phases A and
C, and the voltage for phase B is calculated from measurements of
phase A and C. V2 is connected to neutral for the internal power
supply.
