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 2wire lines of two different systems, single-phase 3-wire lines, and 3-phase 3wire 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 timeseries 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.

5.1 Analyses and Display Screens

_____________________________________________________________________________________________

NOTE

Harmonic wave analysis shows the results of analysis performed on sample data.

Based on analysis results, the rms value and content ratio are calculated independently with a greater number of decimal places than are actually displayed on screen. Therefore, the results calculated for rms value and content ratio may differ slightly from the results obtained by calculating with the values displayed on the screen.

If any of the following conditions is met, power measurement cannot be

erformed.

5.4 Analysis Example 1: Simultaneous Instantaneous Analysis of Two 100-VAC Single-Phase 2-Wire Lines

NOTE

Described below is a method for performing instantaneous analysis of two 100-VAC single-phase 2-wire lines simultaneously using the 8808-51.

In the example, the HIOKI 9018-10 CLAMP ON PROBE is used for current

measurement.

(1) Power supply on

Turn on the power switch for the 8808-51.

(2) Input connection

This equipment is designed to measure input voltage. To measure current, use a voltage-output-type clamp ammeter. We recommend our CLAMP ON PROBE and CLAMP ON HiTESTER for current measurements.

If a clamp ammeter is used to take measurements, the accuracy of both the 880751/8808-51 and the clamp affects the accuracy of measurements. Carefully check the specifications for the CLAMP ON PROBEs and select the unit most appropriate for the specific application. (Refer to Section 10 "Characteristics of Clam

-on Probes."

Before setting the timer trigger, be sure to set the current time in the system screen. (For information on time setting, refer to Section 10.5.1 "Time Setting" in the operating manual for the main unit.)

Make sure the start/end times are set later than the time at which the START button is pressed and measurement starts.

When using a single trigger mode, only one trigger that is tripped at the start time is valid. In such cases, the time interval and end time become invalid (when only the timer trigger function is turned On). Note that the end time setting becomes valid in the following conditions.

1. When the recording length is set to "CONT."

2. When the end time comes before the data of the set recording length is obtained.

To make recordings at regular intervals, set the trigger mode to "REPEAT" and the harmonic wave tri

er to "OFF."

10. Characteristics of CLAMP ON PROBES (Reference Information)

When a CLAMP ON PROBE is used to make measurements, the accuracy of both the CLAMP ON PROBE and the 8807-51/8808-51 will affect measurement accuracy.

In measurements of the direction of a harmonic wave, current value, or other

values, the phase characteristics of the CLAMP ON PROBE significantly affect the measured values. Carefully check the specifications of the

CLAMP ON PROBE and select the most appropriate unit for the specific

measurement application.

The characteristics of HIOKI CLAMP ON PROBES are given below.
