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.

(8) Scaling function

Easy input setting for measurement using a clamp ammeter

(9) Equipped with anti-aliasing filter

Built-in low-pass filter prevents return distortion by eliminating all

frequencies other than measurement targets.

(10) Over-range check function

Automatically switches to a lower sensitivity range when an input waveform

exceeds the maximum input voltage.

3.1 Function Setting

3.2 Measurement Target Setting

UNIQUE

(Independent

channels)

Conducts power analysis only when

odd-number channel receives

voltage input and even-number

channel receives current input

(clamp). (Any input type can be

set.)

1P2W

Single-phase

2-wire

Analyzes single-phase 2-wire line.

Perform the setting so that odd-

number channels receive voltage

input and even-number channels

receive current input (clamp). (The

8808-51 can analyze two single-

phase 2-wire lines simultaneously.)

1P3W

(Single-phase

3-wire)

Analyzes single-phase 3-wire line.

(8808-51 only)

3P3W

(3-phase 3-

wire)

Analyzes 3-phase 3-wire line.

(8808-51 only)

3. Basic Setting Items

The 8807-51 and 8808-51 each provide a total of four functions.

To use the harmonic wave analysis function, follow the procedures given

below.

Setting Screen SET >>STATUS(1/4)/ CHANNEL(2/4)/ TRIGGER(3/4)/ ANALYZE(4/4)

1. Move the flashing cursor to the location shown

in the diagram.

2. Using the buttons, select HARM.

This screen is used to select the power supply type to be measured.

Setting Screen SET >>CHANNEL(2/4)

1. Move the flashing cursor to Wiring.

2. Make a setting using the buttons.

4.1 Waveform Display Color Setting

List OFF Does not display

waveform.

Red/Green Prints waveform at

standard print density.

Yellow/Light

Blue

Prints waveform at low

print density.

Blue/Gray Prints waveform at high

print density.

4. Analog Input Channel Setting

In instantaneous analysis mode, you can select the color of the displayed

waveform.

Setting Screen SET >>CHANNEL(2/4)

1. Move the flashing cursor to the location next to

the channel to be set, as shown in the diagram.

2. Make a setting using the buttons.

When the 8992 PRINTER UNIT is used to print a

waveform, the three print densities are used to

represent the selected waveform display color (6

colors).

Print density has no effect in real-time printing.

(*)When a 3283, 3284, or 3285 CLAMP ON

HiTESTER is selected, power analysis

(harmonic wave active power, harmonic wave

power content ratio, harmonic wave power

phase angle, active power, apparent power,

reactive power, power factor) cannot be

performed due to the phase characteristics.

If the 3283, 3284, or 3285 is selected, the

following warning message is displayed when

power analysis begins.

"Warning 635: 3283,3284,3285 can't analyze

power."

HiTESTER

Set the same measurement range for the 8807-51/8808-51 and the clamp.

Accurate measurements are not possible if improper ranges are set.

When using the 3283, 3284 or 3295 CLAMP ON HiTESTER for current

measurement, press the OUTPUT button on the 3283/3284/3285 unit and set to

MON

(

waveform out

ut: AC

)

The input type must be set for each analog input channel.

Voltage and current in combination with the HIOKI Clamp Sensor can be

measured.

When the name of clamp is selected, measurements are automatically

converted to current values and displayed.
