Harmonic analysis page 

 

In the DCRG8 it is possible to enable the calculation of the FFT 
harmonic analysis up to the 31st order of the following measurements: 

o

 

phase-to-phase voltages 

o

 

phase-to-neutral voltages 

o

 

currents 

 

For each of these measurements, there is a display page that graphically 
represents the harmonic content (spectrum) through a bar graph. 

 

Every column is related to one harmonic order, even and odd. The first 
column shows the total harmonic distortion (THD). 

 

Every histogram bar is then divided into three parts, one each phase 
L1,L2, L3. 

 

The value of the harmonic content is expressed as a percentage with 
respect to the fundamental (system frequency). 

 

It is possible to show the harmonic content in numeric format, selecting 
the required order through 

and ►.  The lower part of the screen will 

display a little arrow that points to the selected column, and the relative 
percentage value of the three phases.  

 

The vertical scale of the graph is automatically selected among four full-
scale values, depending on the column with the highest value. 

 

Страница анализа гармоник

 

 

Устройство DCRG8 позволяет включить расчет анализа гармоник FFT до 31-
го порядка следующих измерений: 

o

 

междуфазное напряжение 

o

 

напряжение «фаза-нейтраль» 

o

 

сила тока 

 

На каждое из этих измерений имеется страница экрана, на которой 

графически в форме гистограммы представлен коэффициент гармоник 
(спектр). 

 

Каждый столбец относится к одному порядку гармоники – четному и 
нечетному. Первый столбец отражает коэффициент нелинейных искажений 

(КНИ). 

 

Далее каждый столбец гистограммы делится на три части – на каждую фазу 

L1, L2, L3. 

 

Величина коэффициента гармоник выражена в виде процента с учетом 

основной частоты (частота системы). 

 

Коэффициент гармоник можно отобразить в числовом формате, выбрав 

необходимый порядок с помощью кнопок 

 и  ►.  В нижней части экрана 

имеется небольшая стрелка в направлении выбранного столбца, а также 

показаны относительные процентные величины для трех фаз.  

 

Вертикальная шкала графика выбирается автоматически из четырех 

предельных значений в зависимости от столбца с самым высоким 

значением. 

 

 

   

 

 

   

 

Waveform page 

 

This page graphically views the waveform of the voltage and current 
signals read by the DCRG8. 

 

It is possible to see one phase at a time, selecting it with 

 

key. 

 

The vertical scale (amplitude) is automatically scaled in order to fit the 
waveform on the screen in the best possible way. 

 

The horizontal axis (time) shows two consecutive periods referred to the 
fundamental frequency. 

 

The graph is automatically updated about every 1s. 

 

   

Страницы формы сигнала

 

 

На этой странице графически представлена волна сигналов напряжения и 
тока, считываемых устройством DCRG8. 

 

Одновременно можно просматривать только одну фазу с помощью кнопки 

 

Вертикальная шкала (амплитуда) масштабируется автоматически в 
зависимости от размера формы сигналов на экране для достижения 

наиболее удобного представления. 

 

На горизонтальной оси (время) представлены два последовательных 

периода, относящихся к основной частоте. 

 

График обновляется автоматически с интервалом в 1 секунду.
