Page 5: Basic Features
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. - Page 6 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 •...

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. •... -
Page 8: Analysis Modes
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). •... -
Page 9: Installation & Start-Up
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. -
Page 10: Connection Terminal
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. -
Page 11: Communication Cables For Rj Connectors
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 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. -
Page 12: Starting The Qna-P/Pv Analyzer
Voltage: 100-240 V AC (QNA-P) Voltage: 100-400 ± 30% V c.a (QNA-PV). Frequency: 50... 60 Hz. 2) Ground terminal: The ground terminal of the analyzer must be connected to earth. If it is not connected some of the protective parts may not work properly. - Page 13 Points to consider: Voltage values flashing on the display is a sign that the analyzer is incorrectly installed or configured. Possible causes might be: − The analyzer detects an event: This can mean a real event in the network, or a wrong rated voltage setting where the set value does not match the actual network voltage.

Page 17: The Qna-P/Pv Analyzer's Internal Battery
6.- THE QNA-P/PV ANALYZER’S INTERNAL BATTERY The analyzer has an internal battery to ensure power supply to the analyzer when any event occurs. This battery keeps the analyzer continuously powered for 2-4 hours in the event of the mains power supply being cut. This operating period after voltage supply loss is user-programmable in order to save the battery and to ensure that any possible intermittent voltage interruptions are detected. -
Page 18: Turning The Analyzer On
7.2.- Turning the analyzer on When the QNA-P/PV is turned on, the first screen appears with the analyzer’s identification: After some seconds, the display will show a screen displaying the three voltages measured by QNA-P/PV in each phase. Use the buttons to move through each available display screen. -

Remarks The QNA-P/PV analyzer may indicate that it is incorrectly installed or configured. Possible causes might be: • Voltage values flashing on the display. Possible causes might be: − The analyzer detects an event: This can mean a real event in the network, or a wrong rated voltage setting where the set value does not match the actual network voltage.. -
Page 20: Features Of The Monitored Electrical Network
8.1.2.- Features of the monitored electrical network • Rated voltage: The rated voltage of the power system to be monitored by the QNA-P/PV analyzer. For a 3-wire configuration the line-to-line voltage must be set (ex. 400 V~), and for a 4-wire configuration the line-to-neutral voltage must be set (ex. - Page 21 Voltage swell hysteresis: A voltage swell hysteresis value can be defined at • a different value for the voltage swell event starting and finishing. Therefore, a voltage swell event starts when the voltage swell threshold is exceeded and ends when the voltage value is below the value defined by subtracting the voltage swell hysteresis value from the voltage swell threshold.

The following incidents may be detected and recorded by the QNA-P/PV: Battery OFF: Indication of the time when QNA-P/PV stopped operating. This time depends on the value set by the user for the operating period after a voltage supply loss. -
