Introduction This introduction is not part of IEEE Std 1159-2009, IEEE Recommended Practice for Monitoring Electric Power Quality. This recommended practice encompasses the monitoring of electrical quality
3、 of single-phase and polyphase ac power systems. It is important that all power quality monitors, as well as users of monitors and monitoring data, use consistent terminology and definitions of power quality phenomena. Therefore, this recommended practice provides consistent descriptions of electrom
4、agnetic phenomena occurring on power systems. It describes nominal conditions of the power supply and of deviations from these nominal conditions that may originate within the power supply or in the load equipment or may originate from interactions between the source and the load. Monitoring and mea
5、surements can be utilized for power system performance studies as well as compatibility assessment. Brief, generic descriptions of load susceptibility to deviations from nominal power supply conditions are presented to identify which deviations may be of interest. Further, this recommended practice
6、discusses the selection of appropriate measuring instruments, limitations of these instruments, application techniques, and the interpretation of monitoring results. While there is no implied limitation on the voltage rating of the power system being monitored, signal inputs to monitoring instrument
7、s are generally limited to 1000 V ac root mean square (rms) or less. Instrument transformers and attenuators enable the use of monitoring equipment on a wide range of voltages and currents. Typically, the frequency ratings of the ac power systems being monitored are in the range of 45 Hz to 450 Hz.
8、Some monitors can also acquire dc signals from the load or control system to assist in the interpretation of load response to deviations from the nominal. The interpretation of dc signals is beyond the scope of this recommended practice. It is also recognized that these instruments may perform monit
9、oring functions for environmental conditions (e.g., temperature, humidity, high-frequency electromagnetic radiation); however, the scope of this recommended practice is limited to conducted electrical parameters derived from ac voltage or current measurements, or both. The definitions presented and
10、used in this recommended practice are intended solely for characterizing common electromagnetic phenomena to facilitate communication between various sectors of the power quality community. The definitions are not intended to represent performance standards or equipment tolerances. For example, elec
11、tric power providers (e.g., electric utilities) may utilize different thresholds for undervoltage and overvoltage in the supply from the descriptions in Table 2. On the other hand, sensitive equipment may malfunction due to electromagnetic phenomena that lie within the thresholds of the Table 2 crit
12、eria. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations.

Overview 1.1 Scope This recommended practice encompasses the monitoring of electrical characteristics of single-phase and polyphase ac power systems. It includes consistent descriptions of conducted electromagnetic phenomena occurring on
41、 power systems. This recommended practice presents definitions of nominal conditions and deviations from these nominal conditions that may originate within the source of supply or load equipment or may originate from interactions between the source and the load. Also, this recommended practice discu
42、sses measurement techniques, application techniques, and the interpretation of monitoring results. 1.2 Purpose The use of equipment that causes and is susceptible to various electromagnetic phenomena has heightened the interest in power quality. An increase in operational problems has led to a varie
43、ty of attempts to describe the phenomena. Because different segments of the technical community have used different terminologies to describe these electromagnetic events, this recommended practice provides users with a consistent set of terms and definitions for describing these events. An understa
44、nding of how power quality events impact the power system and end-use equipment is required in order to make monitoring useful. Proper measuring techniques are required to safely obtain useful, accurate data. Appropriate location of monitors, systematic studies, and interpretation of results will en
45、hance the value of power quality monitoring. The purpose of this recommended practice is to assist users as well as equipment and software manufacturers and vendors by describing techniques for defining, measuring, quantifying, and interpreting electromagnetic disturbances on the power system.
