3.8 Harmonics / interharmonics
Harmonics presents voltage and current signals as a sum of sinusoids of power
frequency and its integer multiples. Sinusoidal wave with frequency k-times higher than
fundamental (k is an integer) is called harmonic wave and is denoted with amplitude
and a phase shift (phase angle) to a fundamental frequency signal. If a signal
decomposition with Fourier transformation results with presence of a frequency that is
not integer multiple of fundamental, this frequency is called interharmonic frequency and
component with such frequency is called interharmonic. See 5.1.7 for details.

3.13 Signalling
Mains signalling voltage, called “ripple control signal” in certain applications, is a burst of
signals, often applied at a non-harmonic frequency, that remotely control industrial
equipment, revenue meters, and other devices. Before observing signalling
measurements, user should set-up signalling frequencies in signalling setup menu (see
section 3.19.4).
Results can be seen in a tabular (METER) or a graphical form (TREND) - which is
active only while GENERAL RECORDER is active. See section 3.14 for instructions
how to start recording. In order to understand meanings of particular parameter see

4 Recording Practice and Instrument
Connection
In following section recommended measurement and recording practice is described.
4.1 Measurement campaign
Power quality measurements are specific type of measurements, which can last many
days, and mostly they are performed only once. Usually recording campaign is
performed to:
Statistically analyse some points in the network.
Troubleshoot malfunctioning device or machine.
Since measurements are mostly performed only once, it is very important to properly set
measuring equipment. Measuring with wrong settings can lead to false or useless
measurement results. Therefore instrument and user should be fully prepared before
measurement begins.
In this section recommended recorder procedure is shown. We recommend to strictly
follow guidelines in order to avoid common problems and measurement mistakes.
Figure below shortly summarizes recommended measurement practice. Each step is
then described in details.
Note: PC software PowerView v3.0 has the ability to correct (after measurement is
done):
wrong real-time settings,
wrong current and voltage scaling factors.
Preform measuremement
Save waveform snapshoots
Step 4:
On Line Measurement
Prepare instrument for new measurement,
before going to measuring site. Check:
Is it time and date correct?
Are batteries in good condition?
Is it Memory List empty? If it is not,
download all data from previous
measurements and release storage for
new measurement.
Setup Power Master according
to the measurement point
nominal voltage, currents, load
type. Optionally enable events or
alarms and define parameter
thresholds.
Double check Measurement setup
using Phase diagram, and various
scope and metering screens
Using power metering check if
power is flowing in right direction
(power should be positive for load
and negative for generator
measurements)

Page 99
MI 2883 Energy Master Recording Practice and Instrument Connection
Step 1: Instrument setup
On site measurements can be very stressful, and therefore it is good practice to prepare
measurement equipment in an office. Preparation of Energy Master include following
steps:
Always use batteries that are in good condition and fully charge them before you
leave an office.
Note: In problematic PQ environment where dips and interrupts frequently occurs
instrument power supply fully depends on batteries! Keep your batteries in good
condition.
Download all previous records from instrument and clear the memory. (See
section 3.17 for instruction regarding memory clearing).
Set instrument time and date. (See section 3.20.1 for instruction regarding time
and date settings).
Step 2: Measurement setup
Measurement setup adjustment is performed on measured site, after we find out details
regarding nominal voltage, currents, type of wiring etc.
Step 2.1: Synchronization and wiring
Connect current clamps and voltage tips to the “Device under measurement”
(See section 4.2 for details).
Select proper type of connection in “Connection setup” menu (See section 3.19.1
for details).
Select synchronization channel. Synchronization to voltage is recommended,
unless measurement is performed on highly distorted loads, such as PWM
drives. In that case current synchronization can be more appropriate. (See
section 3.19.1 for details).
Select System frequency. System frequency is default mains system frequency.
Setting this parameter is recommended if to measure signalling or flickers.
Step 2.2: Nominal voltage and ratio
Select instrument nominal voltage according to the network nominal voltage.
Note: For 4W and 1W measurement all voltages are specified as phase-toneutral (L-N). For 3W and Open Delta measurements all voltages are specifies
as phase-to-phase (L-L).
Note: Instrument assures proper measurement up to 150 % of chosen nominal
voltage.
In case of indirect voltage measurement, select appropriate “Voltage ratio”
parameters, according to transducer ratio. (See section 3.19.1 and 4.2.2 for
details).
99
Page 100
MI 2883 Energy Master Recording Practice and Instrument Connection
Step 2.3: Current clamps setup
Using “Select Clamps” menu, select proper Phase and Neutral channel current
clamps (see sections 3.19.1 for details).
Select proper clamps parameters according to the type of connection (see
section 4.2.3 for details).
Step 2.4: Event setup
Select threshold values for: swell, dip and interrupts (see sections 3.19.2 and 3.15 for
details).
Step 2.5: Alarm setup
Use this step if you would like only to check if some quantities cross some predefined
boundaries (see sections 3.16 and 3.19.3 for details).
Step 2.6: Signalling setup
Use this step only if you are interested in measuring mains signalling voltage. See
section 3.19.4 for details.
Step 3: Inspection
After setup instrument and measurement is finished, user need to re-check if everything
is connected and configured properly. Following steps are recommended:
Using PHASE DIAGRAM menu check if voltage and current phase sequence is
right regarding to the system. Additionally check if current has right direction.
Using U, I, f menu check if voltage and current have proper values.
Check voltage and current THD.
Note: ExcessiveTHD can indicate that too small range was chosen!
Note: In case of AD converter overvoltage or overloading current, icon will
be displayed.
Using POWER menu check signs and indices of active, nonactive, apparrent
power and power factor.
If any of these steps give you suspicious measurement results, return to Step 2 and
double check measurement setup parameters.
Step 4: On-line measurement
Instrument is now ready for measurement. Observe on line parameters of voltage,
current, power, harmonics, etc. according to the measurement protocol or customer
demands.
Note: Use waveform snapshots to capture important measurement. Waveform
snapshot capture all power quality signatures at once (voltage, current, power,
harmonics, flickers).
Step 5: Recorder setup and recording
Using GENERAL RECORDER menu select type of recording and configure recording
parameters such as:
