4.2 Harmonics
Harmonics can be a huge hazard in electrical system, especially old ones. Test of
harmonics is very important. This device tests THD and harmonic voltage and harmonic
current for all phases with trend and spectrum (histogram). For comparison of testing
value with international standar ds like EN 50160, pl ease refer t o 7. PITE 3 5 61 DATAVIEW

select any two harmonics that will display in TRE. (Selectable in Fig.4.2.4).
TRE.: It presents the trending for measuring data. Click the top center; you could switch
between the two presett in g harmonics (Fig.4.2.4).
4.3 Power & Energy
This is for testing both Pow er and Energy. They include the functions as be lo w:
Power: 3-phase apparent power (kVA), ac tive pow er ( kW), reactive pow er (kV AR), pow er
factor (PF), voltage (V), current (A) and phase angle.
Energy: 3-phase apparent energy (kVA), activ e energy (kW), reactive energy (kVAR),
power factor, kVAh, kWh and kVARh.
In energy testing, the analyzer measures power consumpti on by integrated power
measurement over time. Y ou could use this function for quick verificat ion of revenue
meters.
To get started, click “POWER & ENERGY” in main menu and wait for 5 seconds, you will
come to the screen below:

by Clicking the button TRE.. These two items could be switched to each other in the
option box on the top (Fig.4.3.4).
4.4 Unbalance
Unbalance is expressed as the ratio of negative sequence and null sequence to positive
sequence components. A perfect balanced system has no negative sequence or null
sequence component s .
Before testing measurement of unbalance, you could alternatively set initial angle and
angle range of different way. For inst ruc t i on, please refer to 5.5 Phase Angle Setting.
Unbalance measurement will test 3-phase unbalance for both voltage and current. Click
UNBALANCE in the main menu and wa it for 5 seconds to start testing as Fig 4.4. 1.
It presents the 3-phase unbalance in negative sequence (“Ne.s.”), positive sequence
(“Po.s.”) and zero sequence (“Nu.s.”).
Fig 4.4.1
The data could also be v iew ed in vect or when y ou click th e butt on VECT and click TRE to
view the tendency of measurement data. I t will trac k the changes o f unbalanc e as dif ferent
loads come on and of f line.

4.5 Record
In the function “RECORD”, PITE 3561 will become a monitor for the testing functions of
Volt age/c urrent/fre quency, Power, Harm onics, Unbalance and Flic ker simultaneously. This
function will help you uncover some hard-to-find or intermittent issues by recording all the
testing data. Maximally PITE 3561 can r ecord up t o 960 hours wit h interv al of more than 2
minutes and 59 seconds. It will capture shorter time duration with recording inter val as low
as 3 second.
Page 15
PITE 3561 Power Quality Analyzer

Click ”RECORD” in the main menu you wi l l come to the next screen for parameter setting
as below:
Fig. 4.5.1 Fig. 4.5.2
Firstly do all the parameter settings. To change the way of wiring, please refer to 5.2.2
Parameter Setting. As recording interval changes, maximum recording time will
automatically be calculated.
After the setting, click START to proceed with recording measurement. The testing record
will be automatically saved in m ain unit memory. To vie w this information, please refer to
5.1 Data Management. Screen will display live data simultaneously for all functions. Click
on the left top box to shift to other events like harmonics, flic ker a nd s o on.
NOTE: To ensure sufficient power supply during data recording, you are suggested to
connect the Analyzer with proper AC source with power adaptor.
4.6 Fluctuation/ Flick er
Flicker measurement gives an indication of whether voltage fluctuations will cause
annoyance for a typical person working under incandescent lighting (60W). A reading
higher than 1 means most people will perceive the voltage changes. The testing is
optimized on a incandescent lighting powered by 120V/50Hz or 230V/60Hz. Short-term
flicker (Pst) and long-term flicker (Plt) for each phase will be displayed.
Voltage fluctuation is defined as a seri es of high-speed variation or continuous change of
voltage rms. variation cycle is more than power frequency cy cle. In pow er sy stem, volt age
fluctuation could happen many times. Variation process could be regular or irregular.
Voltage fluctuation is normally described as relative voltage fluctuation. It is numbered as
the ratio of two nearby extremums (keep changing in series of voltage rms) difference to
rated voltage.
Click “FLICKER“in the main menu, input the rated voltage an d wait for 6 secon ds, you w ill
see the screen as below (Fig. 4. 6. 2) . If there is any event, it will be displayed on the
screen.
Page 16
PITE 3561 Power Quality Analyzer
16
Fig. 4.6.1 Fig. 4.6.2
4.7 Dips/ Swells
Dips & Swells are used to recor d t r ansient changes of voltage as short as h al f a c ycle.
When the rms voltage exceeds the nominal voltage by 10 to 80% for 0.5 cycle to 1 minute,
the event is called a "swell".
A "dip" (in British English) or a ”sag" (in American English - the two terms are equivalent)
is the opposite situation: the rms voltage is below the nominal voltag e by 10 to 90% for 0. 5
cycle to 1 minute.
Dips & Swells mode makes rapid rms voltage and current r eadings on all phases.
To begin the test, clic k “Dips & Swells” for parameter settings.
Input the nominal voltage, s well t hresho ld and d ip thr esho ld, an d clic k START to carry out
the test. You will see the waveform in Fig 4.7.2. In this screen, nominal voltage is defined
as 100%. For example, if no minal voltage is 220V, then 264V will be descr ibed as 20%
upper. 176V will be described as 20% lower.
Fig 4.7.1 Fig 4.7.2
4.8 Inrush
Inrush is the dash current happens w hen there is high load or low impedance load.
Generally, when the load is in normal working condition, current will be stabilized after
some time, like the duration after so m e bi g loads (e.g. motor and frequency converter)
starts.
Inrush testing function could record the variation trend from dash curre nt to current
stabilization. This process is called one inrush.
Click “INRUSH” in main menu, you will come to the screen for par ameter setting as Fig
4.8.1.
Page 17
PITE 3561 Power Quality Analyzer
17
“Expected T” indicates th e expected time for testing inrush.
“Max Amp” indicates the maximal cur r ent t hat expected inrush may reach.
“Nominal Amp” indicates the curr ent value of device under normal working c ondition.
“Threshold”: it is call ed one inrush when current value reaches t he pr esetting threshold.
Fig 4.8.1 Fig 4.8.2
Nominal current is used as standard (100%), if current v alue reaches thresh old, it is called
one event. If nominal current is 20A, threshold is set as 30A. 30A is at 150% .
“Max Amp” is the maximal c urr ent that can be displayed during testing of inr ush.
For exact time when inrush happ ens , users can refer to PC software of PITE 3561.
After the parameter sett in g, click the button START to begin the test Fig 4.8.2.
PITE 3561 will automatically keep record when inrush is detected. To manually quit the
testing, please click the but ton BACK.
4.9 Scope
Oscilloscope function in PITE 3561 could simultaneously testing 3 phase 4 wire power
