2.1.- Basic features
The QNA-P/PV is an analyzer specifically designed to check electrical power
supply quality in accordance with the IEC 61000-4-30 standard.
In addition to the A.C. voltage inputs (insulated by transformers), the
instrument is equipped with 4 inputs of 2V (clamps) . which allows the QNA-P/PV to
also be used as a network analyzer.
Its design in suitcase of high robustness (IP67) that makes an equipment ideal
to measure in severe environmental conditions.
Moreover, the great variety of available models makes the QNA-P/PV suitable
for any situation and communication mode.
The instrument’s internal battery ensures continuity of measurement by the
QNA-P/PV analyzer in the event of any loss in voltage supply (short or long-term line
interruption).
QNA-P/PV is equipped with three A.C. voltage inputs which permit
simultaneous voltage measurement in all three phases, together with frequency
measurement in any power system.
To analyse electrical power supply quality in accordance with IEC 61000-4-30,
the QNA-P/PV uses a DSP to analyse all cycles from all three voltage phases to
detect the occurrence of any event (voltage dip, voltage swell, interruption).
Harmonic and flicker is also calculated in accordance with IEC61000-4-7 and
61000-4-15, respectively,.
The QNA-P/PV’s input 2V (2V / 5A) can analyse the main electrical
parameters in 4 quadrants (Energy consumption and generation).
The QNA also has a Neutral current entry and another for Neutral-Earth
voltage measurement. These parameters complete the information that the QNA is
able to supply to study the electric network.
The QNA-P/PV analyzer is equipped with a built in 4 Mbytes memory to
receive quality, events and electrical parameters.

The different information recorded in the QNA-P/PV’s built in memory is
distributed in four file types:
• *.STD files: This file contains all periodically recorded values (voltage,
current, frequency, power, energy, flicker, harmonic distortion, harmonic
content, unbalance).
• *.EVE files: File containing all incidents referred to the QNA-P/PV itself (file
readout, setup modification, memory erasure, power supply on/off, battery
on/off...).
• *.EVQ: This file contains all events observed in the electrical power supply
(voltage dips, voltage swells, interruptions) together with supplementary
information about these events (time of the event occurring,
maximum/minimum voltage, average voltage, voltage prior to the event).
• *.H24: This file contains the data required to obtain a statistical analysis of
the harmonic evolution in one day.
• *.STP: This file stores average values for voltage, frequency, flicker (pst
and plt) and the THD over one week.
Measurable parameters by the QNA-P/PV analyzer are listed below:
Parameters L1 L2 L3

Active power X X X
Reactive power L X X X
Reactive power C X X X

The above parameters will be measured and recorded regardless of energy
consumption or generation in the installation.

2.2.- Electrical features
Using the QNA-P/PV as a recording instrument for evaluating electrical power
supply quality means that the analyzer must have a high degree of protection against
severe electrical conditions:
• High-energy varistors absorbing surges to avoid any costly repairs.
• Noise filters in voltage and current inputs to ensure reliable measurements even
under the most adverse operation conditions.
• Power supply: transformers with extra power dissipation and insulation.
• Built-in battery power supply to ensure voltage supply to the QNA-P/PV analyzer
in the event of voltage loss.
• Insulation transformers guaranteeing the proper insulation of inputs.

3.- ANALYSIS MODES
QNA-P/PV series analyzers can be used in different operating modes
according to their setting.
The most striking features of the analysers are:
• Measurement and storage in memory of main power quality parameters
(voltage values, flicker, harmonics and unbalance).
• Measurement and storage in memory of main electrical parameters (voltages,
currents, frequency, power, PF...).
• Neutral current and Neutral-Earth voltage measurement.
• Setting a voltage threshold to define different events (voltage sags, voltage
swells and interruptions). Also an optional setting of an hysteresis value for
each individual threshold.
• QNA-P/PV can carry out quality analyses in 3-wire or 4-wire distribution
systems. All quality measurements will be referred the line-to-neutral or line-toline voltage according to selection.
• QNA-P/PV can also be used to measure through voltage and current
measuring transformers.
4.- DATA STORAGE IN MEMORY (AUTOMATIC MODE)
QNA-P/PV is equipped with an internal date and time clock to store automatic
data recordings and quality events in the memory at regular time intervals..
The QNA-P/PV storage memory is divided into four independent blocks. Each
discrete block is allocated to every file type to be saved. Every file type contains the
following information:
• *.STD files: This file contains all values which are periodically
recorded (voltage, current, energy, frequency, voltage harmonic
distortion, harmonic content and unbalance…).
• *.EVE files: File containing all incidents referred to the QNA-P/PV
itself (file readout, setup modification, memory erasure, power
supply on/off, battery on/off...).
• *.EVQ: This file contains all events observed in the electrical power
supply (voltage dips, voltage swells, interruptions) together with
supplementary information about these events (time of the event
occurring, maximum/minimum voltage, average voltage, voltage
prior to the event).
• *.H24: This file contains the data required to obtain a statistical
analysis of the harmonic evolution in one day.
• *.STP: This file stores average values for voltage, frequency, flicker
(pst and plt) and the THD over one week.

QNA-P/PV is equipped with a built in rotating memory for data collection; this
means that once this memory is full, new values overwrite the oldest ones. Therefore,
if no data is to be lost, data must be retrieved from the memory before the oldest
values are overwritten.
5.- INSTALLATION & START-UP
This manual contains information and warnings about the
QNA-P/PV analyzer which must be followed to guarantee the proper
operation of all instrument functions and to maintain it in a safe
condition.
If the instrument is not used according to the manufacturer’s
specifications, the instrument’s protection may be damaged Note that when the
instrument is switched on, the terminals may be dangerous when touched and
opening or removing parts may access dangerous areas. Therefore, the instrument
must not be used until it is properly installed
Where any protection failure is suspected to exist (for example,
if there are signs of external damage), the instrument must be
immediately switched OFF. In the event of this contact a
qualified technician.

5.1.- Connection terminal
The QNA-P/PV analyzer may be installed in any three-phase distribution line with
neutral conductor (4 wires) or without neutral conductor (3 wires). Measurements
solely depend on the connection mode and the analyzer configuration
The connection of an earth terminal is essential to ensure
the efficiency of QNA-P/PV protection elements.

5.1.1.- Communication cables for RJ connectors
The most usual configurations for QNA-P/PV communication cables are as
follows:
• RS-232 connection to PC or to external modem:
QNA-P/PV
PC
1–DSR 5–GND
2–Rx 3–Tx
3–TX 2–Rx
4–CTS 7–RTS
5–RTS 8–CTS
6–GND 5–GND
The RS-232 communication cables must always be disconnected to
establish communication with a QNA-P/PV-
GPRS/GSM via a mobile phone. If
the RS-232 is connected, then modem operation is completely disabled.
