12.1. VOLTAGE ANOMALIES
• 说明：The instrument catalogs as voltage anomalies (sags, swells) all those RMS values,
• 说明：calculated every 10ms (@ 50Hz), which are out of the thresholds set upon configuration by
• 说明：±1% to ±30% of a set reference value with a 1% step.
• 说明：To prevent recording events attributable to electric noise only, a hysteresis threshold of
• 说明：1% is also present. These limits remain unchanged throughout the whole recording period.
• 说明：The reference voltage value must be set as:
• ➢ Rated voltage Phase-Neutral：for single-phase and three-phase 4-wire systems
• ➢ Rated voltage Phase-Earth：for three-phase 3-wire systems
• Example：Three-phase 4-wire system.
• 说明：Vref = 230V, LIM(+) = 10%, LIM(-) = 10%, => Hysteresis 1%
• 说明：Higher Lim = 230 + 23 = 253V, Lower Lim = 230 - 23 = 207V
• 说明：Recording swells
• 说明：The instrument starts recording an event if voltage exceeds 253V and stops recording if
• 说明：voltage drops below 253 – 2.53 = 250.5V
• 说明：Recording sags
• 说明：The instrument starts recording an event if voltage is lower 207V and stops recording if
• 说明：voltage rises over 207 + 2.07 = 209.1V
• 说明：For each event, the instrument records the following data:
• 说明：• The number corresponding to the phase in which the anomaly occurred.
• • The “direction” of the anomaly：“UP” and “DN” respectively identify voltage swell and
• 说明：sags
• 说明：• The date and time in which the event starts in a format day, month, year, hour, minutes,
• 说明：seconds, hundredth of seconds.
• 说明：• The duration of the event, in seconds with a resolution equal to 10ms.
• 说明：• The minimum (or maximum) value of voltage during the event.
• 说明：EN – 22
12.2. VOLTAGE AND CURRENT HARMONICS
• 说明：Any periodic non-sinusoidal wave may be represented by a sum of sinusoidal waves, each
• 说明：with a frequency which is a whole multiple of the fundamental, according to the
• 说明：relationship:
• 说明：v ( t ) V
• 说明：k 1
• 说明：V
• 说明：k
• 说明：s i n (
• 说明：k
• 说明：t
• 说明：k
• 说明：) = + ∑
• 说明：∞
• 说明：=
• 说明：+
• 说明：(1)
• 说明：where:
• 说明：V = Average value of v(t)
• 说明：V = Amplitude of the fundamental of v(t)
• 说明：V = Amplitude of the k-nth harmonic of v(t)
• 说明：k
• 说明：For network voltage, the fundamental has a frequency of 50 Hz, the second harmonic has
• 说明：a frequency of 100 Hz, the third harmonic has a frequency of 150 Hz and so on. Harmonic
• 说明：distortion is a continuous problem and must not be confused with short-duration
• 说明：phenomena such as peaks, drops or fluctuations. It can be seen how in (1) the index of the
• 说明：summation goes from 1 to infinity. What actually happens is that each signal has an
• unlimited number of harmonics：there is always a sequence number beyond which the
12.2. VOLTAGE AND CURRENT HARMONICS · value of the harmonics is negligible.
• 说明：Effect of the sum of 2 multiple frequencies.
• 说明：Standard EN 50160 suggests cutting the summation in the expression (1) at the 40th
• 说明：harmonic. A fundamental index to detect the presence of harmonics is the THD defined as:
• 说明：EN – 23
• 说明：T H D v =
• 说明：4 0
• 说明：∑h
• 说明：= 2
• 说明：V
• 说明：V 2h
• 说明：This index takes into consideration the presence of all harmonics, and the more distorted
• 说明：is the waveform, the higher is the index.
