1 Power Quality Electrical power quality is the measurement and analysis of the voltage delivered to customers. These parameters (voltage amplitude, fl icker, harmonics, unbalance) describe the voltage waveform and offer very important information about the effi ciency of the electrical installation being analysed. A poor electrical supply may affect electrical installations in very different ways and cause signifi cant problems in the installation and connected electrical equipment There are currently a series of International standards that defi ne not only minimum levels of electrical power quality but also how to measure these parameters. Events These are voltage variations which affect the effective value of the half cycle of the voltage wave. According to this value, compared as a percentage to the declared nominal voltage at the point of measurement, events are classifi ed in the following way: Interruptions: Voltage event where the effective value is below 10 % (or 1 % according to criteria used) of the declared nominal voltage. Dips/ Sags: Events with values between 90 % and 10 % (or 1 % according to criteria used) of UDIN Dips/sags are drops in voltage caused by the variation of the system s impedance due to protective devices operating and usually last between 10 ms and 1 min. Overvoltages: A phenomenon where the voltage increases above 110 % of the declared voltage (107 % according to criteria used). These are classifi ed as temporary (when the duration is relatively long) or transient (when the duration is a few milliseconds). Overvoltage Dips Interruptions IEC This Standard describes the measurement method which must be used in equipment measuring the quality of electrical supply. This Standard provides two classes of equipment: Class A equipment. For contractual applications, resolving disputes or to be used as a reference. Class B equipment. For obtaining data for internal use where a high degree of accuracy is not required. It is vital that electrical power quality equipment measures in accordance with this Standard including (specifying the class), as it ensures the correct accumulation of results. Q2-2

2 harmonics Disturbance which affects the voltage and current waveform and is caused by nonsinusoidal loads. Generally, harmonics found in the system have relatively low frequencies and are usually responsible for transformers and distribution lines overheating. They are also responsible for generating high currents and losses in the neutral in some installations, overcurrent trips in some protective devices and differential relay trips, etc. Flicker This is periodical voltage amplitude disturbance which has direct repercussions on incandescent light fl uctuations. This effect causes visual annoyance and produces tiredness if the phenomenon is permanent. This perception value has to be measured objectively (Pst). In many quality standards, (EN50160), Pst < 1 is admissible and not damaging.

Communications RS-232 RS-485 GSM GPRS Ethernet SMS The equipment has two communications ports allowing for the following combinations: RS232/RS485 or GSM/RS232. RS-232 Communication. Direct connection to the equipment over short distances. RS-485 Communication. Allows the equipment to be connected within an internal multi-point network with more associated peripherals with one single PC managing everything GSM Communication. (GSM types only). Communication is established through a mobile telephone call. This type of communication is ideal for those installations with difficult access as it avoids requiring a communications cable from the equipment to the PC. GSM QNA 400 Series analyzers have a built in GSM MODEM which reduces the space required for installing the equipment and increases the degree of electrical protection for the MODEM since it is protected by the equipment itself. GPRS Communication (GPRS only). This type of communication is ideal for those companies with a PC operating as a server and who do not want to use modems to download information. Only the Internet address where the information is to be downloaded needs to be provided to communicate via GPRS. GPRS communication allows for the downloading of information at high speeds and in the most economical manner. GPRS equipment allows data to be sent as GSM. QNA 400 Series analyzers use the following communications protocols: CIRBUS: to question the equipment ZMODEM: to download fi les Discharge protection Protection against unforeseen discharges plus radiated and conducted electromagnetic emissions (EMI).
