Instantaneous Analysis and Long-term Recording of Harmonic
Waves for Maintenance of Commercial Power Systems
Are the harmonics in your company's power lines in
order?
The new 8807
-51
/8808
-51
is an economical tool that
will clearly identify and analyze the current harmonic
state of your power system.
To the

MEMORY HiCORDERs
with
their popular detachable printers,
HIOKI
has added the
8807-
51
/8808-
51
MEMORY HiCORDERs
with harmonic
analysis function. Capable of both instantaneous analysis and
time series analysis of harmonics, these units can measure
and analyze harmonic current flowing into and out of a
commercial power system, as well as harmonic components
piggybacking on power line voltage.
Instantaneous harmonic analysis
• Can measure harmonics up to 40 orders from the fundamen-tal
wave
• Analysis display includes RMS value, content factor, phase angle,
active power, and power phase angle for each order of harmonics
(numeric and graphic display)
• Analysis display of total RMS value, total distortion, active/
reactive/apparent power, and power factor (numeric display)
• Bar graph and numeric data display
• Power phase angle can be displayed as a vector
Time series recording
• Harmonic analysis of up to 20 items
• Data recorded in time series
• When analyzing four items
simultaneously, data can be recorded for
up to 150 days
Flexible connection options
• Supports independent channels, single-
phase two-wire, single-phase three-wire,
and three-phase three-wire
• Full isolation of all analog channels
Useful measurement functions
• Connection check
• Level check
• Over-range function

harmonic components (up to 40 orders from the
fundamental wave) that are included in voltage
and current in a power line with a base frequency
of 45 to 65Hz. Based on the waveform that was
captured, the
8807-
51
and
8808-

can analyze
the RMS value, content factor, phase angle, active
power, and power phase angle for each order of
harmonics. The measurement results can be
displayed and recorded as a bar graph, numeric
data, or power vector diagram. The
8807-

and
8808-

can also display numerically the
total RMS value, the total distortion, the active/
reactive/apparent power, and power factor.

Time series analysis mode for continuous measurement of changes in harmonics
This mode is used to continuously measure changes in the
RMS value, content factor, phase angle, active power, and total
distortion for each order of harmonics. Measurements are made
at specific intervals and are displayed and recorded as a graph.
Through long-term monitoring of the correlation between the
timing of harmonic waves and their relationship to phenomena,
the
8807-
51
and
8808-
51
become useful tools for finding the
causes of harmonic interference and taking appropriate action.
Time series graph display screen
In time series recording mode, the
8807-
51
and
8808-
51
are
capable of recording up to 20 harmonic wave analysis items
simultaneously. The recording time can be set over a range
of 30 minutes to 150 days and the data is stored in internal
memory. If "continuous" is set as the recording time, the
8807-
51
and
8808-
51
are able to draw a continuous graph
on recording paper. Only the measurements for the last 60
divisions are stored in internal memory.

The

and

both capable of measurement of
single-phase two-wire lines, while
the
8808-
51
is also capable of
measurement of single-phase three-
wire*, dual single-phase two-wire*,
and three-phase three-wire* lines.
Both units can display numeric data
or a graphs for the active power,
active power content factor, and
power phase angle for each order of
harmonics. Because all analog input
channels are isolated, no problems
are encountered when measuring
two different single-phase two-
wire systems simultaneously, or if
connections are made incorrectly.

only
The
8807-
51
and
8808-
51
both
allow you to input voltage on
channels 1 and 3 and current
on channels 2 and 4
(through the
clamp-on probe)
and then display a
power vector diagram for each
harmonic wave. This diagram
can then be used to determine
whether the harmonic waves are
flowing from the power supply
system or from the load.
