ground window The area through which all grounding conductors, including metallic raceways, enter a specific area It is often used in communications systems through which the building grounding system is connected to an area that would otherwise have no grounding connection harmonic (component) A component of order greater than 1 of the Fourier series of a periodic quantity2 harmonic content The quantity obtained by subtracting the fundamental component from an alternating quantity harmonic distortion Periodic distortion of the sine wave See distortion and total harmonic distortion (THD) harmonic filter On power systems, a device for filtering one or more harmonics from the power system Most are passive combinations of inductance, capacitance, and resistance Newer technologies include active filters that can also address reactive power needs harmonic number The integral number given by the ratio of the frequency of a harmonic to the fundamental frequency2 harmonic resonance A condition in which the power system is resonating near one of the major harmonics being produced by nonlinear elements in the system, thus exacerbating the harmonic distortion impulse A pulse that, for a given application, approximates a unit pulse or a Dirac function2 When used in relation to monitoring power quality, it is preferable to use the term impulsive transient in place of impulse impulsive transient A sudden, nonpower frequency change in the steadystate condition of voltage or current that is unidirectional in polarity (primarily either positive or negative) instantaneous When used to quantify the duration of a short-duration variation as a modifier, this term refers to a time range from one-half cycle to 30 cycles of the power frequency instantaneous reclosing A term commonly applied to reclosing of a utility breaker as quickly as possible after an interrupting fault current Typical times are 18 to 30 cycles interharmonic (component) A frequency component of a periodic quantity that is not an integer multiple of the frequency at which the supply system is designed to operate (eg, 50 or 60 Hz) interruption, momentary (electrical power systems) An interruption of a duration limited to the period required to restore service by automatic or supervisory-controlled switching operations or by manual switching at locations where an operator is immediately available Note: Such switching operations must be completed in a specified time not to exceed 5 min

interruption, momentary (power quality monitoring) A type of short-duration variation The complete loss of voltage (<01 pu) on one or more phase conductors for a time period between 30 cycles and 3 s interruption, sustained (electrical power systems) Any interruption not classified as a momentary interruption interruption, sustained (power quality) A type of long-duration variation The complete loss of voltage (<01 pu) on one or more phase conductors for a time greater than 1 min interruption, temporary A type of short-duration variation The complete loss of voltage (<01 pu) on one or more phase conductors for a time period between 3 s and 1 min inverter A power electronic device that converts direct current to alternating current of either power frequency or a frequency required by an industrial process Common inverters today employ pulse-width modulation to create the desired frequency with minimal harmonic distortion islanding Refers to a condition in which distributed generation is isolated on a portion of the load served by the utility power system It is usually an undesirable situation, although there are situations where controlled islands can improve the system reliability isolated ground An insulated equipment grounding conductor run in the same conduit or raceway as the supply conductors This conductor is insulated from the metallic raceway and all ground points throughout its length It originates at an isolated ground-type receptacle or equipment input terminal block and terminates at the point where neutral and ground are bonded at the power source See NFPA 70-1993, Section 250-74, Exception #4 and Section 250-75, Exception7 isolation Separation of one section of a system from undesired influences of other sections ITI curve A set of curves published by the Information Technology Industry Council (ITI) representing the withstand capabilities of computers connected to 120-V power systems in terms of the magnitude and duration of the voltage disturbance10 The ITI curve replaces the curves originally developed by the ITI s predecessor organization, the Computer Business Equipment Manufacturers Association (CBEMA)9 See CBEMA curve linear load An electrical load device that, in steady-state operation, presents an essentially constant load impedance to the power source throughout the cycle of applied voltage long-duration variation A variation of the rms value of the voltage from nominal voltage for a time greater than 1 min Usually further described using a modifier indicating the magnitude of a voltage variation (eg, undervoltage, overvoltage, or voltage interruption)
