1. General Description
The harmonic wave analysis function is designed exclusively for use with the
8807-51/8808-51 MEMORY HiCORDER.
For detailed information on the product and product functions, please refer
to the manual for the main unit.
Features
(1) A range of harmonic wave analysis functions for commercial
power supplies
The 8807-51 is designed for analysis of single-phase 2-wire lines, while the
8808-51 is intended for analysis of single-phase 2-wire lines, single-phase 2-
wire lines of two different systems, single-phase 3-wire lines, and 3-phase 3-
wire lines.
The function measures power supplies with a fundamental frequency ranging
from 45 to 65 Hz.
(2) Fast Fourier transform in accordance with frequency
512 data points sampled at a rate of 400 kS/s are extracted for calculations.
(3) Two analysis modes to match specific applications
Instantaneous analysis mode for analysis of instantaneous waveforms during
measurement.
Time-series analysis mode for recording and analyzing analysis data as time-
series data.
(4) Extensive analysis items
Six types of analysis of harmonic waves of all degrees rms value, content
ratio, phase angle, active power, power content ratio, and power phase angle
and calculations of total rms value, total distortion, active power, reactive
power, apparent power, and power factor are available.
(5) Instantaneous analysis mode
Displays analysis results as spectral graphs or with numeric values, and
stores result data.
Displays all harmonic wave components from 1st degree to 40th degree on a
single screen.
(6) Time-series analysis mode
Data on 20 phenomena over a period of up to 30 days, or data on four
phenomena over a maximum of 150 days, can be stored in memory.
Four phenomena can be recorded in an overlapping manner on a single time
axis to allow an easy grasp of the interrelationships among phenomena.
The time axis can be set in seven levels from 5 min/DIV to 12 h/DIV.
Smoothing function for cancellation of unexpected phenomena
Pre-trigger function for observation of the signal prior to a trigger
(7) Harmonic wave trigger function
The trigger can be tripped for rms value, content ratio, all degrees power,
power content ratio, power phase angle, total rms value, and any type of
distortion of a selected harmonic wave component.
