HA1600A Power and Harmonics Analyser Harmonics analysis to EN61000-3-2
High speed compliance quality measurements Fluctuations & flicker measurement to EN61000-3-3
High performance power
analyser
The HA1600A is a high speed, high accu-
racy ac power analyser for single phase
loads of up to 16 amps RMS.
Dual power cables allow the supply to the
load to be independent of the supply to the
instrument. The output to the load is via a
front panel mounted ‘standard’ mains con-
nector. A wide range of power connectors is
available including most national types.
The HA1600A can measure Watts, VA,
Volts rms, Volts peak, Amps rms, Amps
peak, Crest factors, THD, Power factor, Fre-
quency and Inrush current.
The large display can show multiple param-
eters simultaneously as well as graphical
representations of voltage and current
waveforms.
Dual 16 bit Analog to Digital converters con-
tinuously sample both voltage and current
and give a wide dynamic range. A fast Digi-
tal Signal Processor gives the performance
needed for continuous real-time analysis of
the data. Advanced algorithms yield accu-
rate results, using extended precision or
floating point arithmetic wherever neces-
sary.

Compliance-quality
harmonics analyser
All electrical equipment sold within the EEC
must comply with legislation relating to the
harmonics content of the current waveform.
The HA1600A has been designed to make
these measurements both quick and simple.
It measures harmonics from the 1st to the
40th and updates the display in real time.
It is suitable for pre-compliance measure-
ments using a normal mains supply and is
capable of full compliance measurements
to EN61000-3-2 in conjunction with a suit-
able power source such as the AC1000A.
Support is provided for both the 2006 and
2000 editions of EN61000-3-2. Capabilities
include continuous monitoring of the supply
voltage, continuous automatic calculation of
harmonic limits, and timed test sequences
with analysis of fluctuating harmonics.
Optional low distortion
1kW power source
The AC1000A is a low cost pure power
source designed specifically for use with a
harmonics analyser such as the HA1600A.
The AC supply available at a standard wall
socket is usually distorted. This comes
about because of nonlinear loads (non–re-
sistive loads) on the AC supply such as
transformers, fluorescent lights,
switched–mode power supplies etc. The ef-
fect of this is to flatten off the top of the sine
wave causing significant distortion.
In a typical factory environment this distor-
tion is so significant that it is easily visible
using the HA1600A waveform display.
EN61000–3–2 requires that the source sup-
ply provides a pure voltage waveform to the
equipment under test. The harmonic cur-
rents can differ significantly when a pure
source is used, so for true compliance
measurements it is important that any test-
ing is performed with a device such as the
AC1000A.
Because of the large increase in the peak
currents that can result from having a pure
sinewave maims voltage supply, the
AC1000A is also very useful for stress test-
ing a wide variety of power supplies types
within electronic equipment.
Compact and portable, the AC1000A is
rated at 1000 V·A for 230 V operation at up
to 35°C ambient.
Maximum continuous rms current is 4.4A
with a peak current capability of 10A.
Overview
The HA1600A is a fast, easy to use mains
and harmonics analyser with a large and
high resolution graphical display, capable
of continuous real-time analysis.
The HA1600A is intended primarily as a
dedicated harmonics and flicker analyser
for compliance quality measurements,
but it can also be used as a general pur-
pose mains analyser.
The unit is available with range of power
connectors to suit different national stan-
dards.
A printer interface is included for record
keepinga/archiving, along with RS-232
and USB interfaces for PC connectivity.
The HA1600A is suitable for both the
product development environment, and
for production line test verification.
HA-PC Link Plus is Windows based
sofware supplied with the HA1600A.
It is intended to assist users in taking
routine compliance measurements and
archiving the results.
It can communicate with the instrument
through either an RS232 or a USB con-
nection.
The AC1000A is an innovative, low cost,
pure power source designed specifically
for use with a harmonics analyser such as
the TTi HA1600A.
It permitts compliance quality measure-
ments to EN61000–3–2 in situations
where the quality of the AC supply is poor
or variable, without the expense of a full
AC power source.
Compliance-quality
fluctuations & flicker meter
The HA1600A can operate as a compliance
quality flicker and fluctuations meter in con-
formance with EN61000-3-3 and
EN61000-4-15.
A current measurement method can be
used, as an alternative to voltage measure-
ment, thus eliminating the need for a refer-
ence impedance.
Flicker severity is measured in terms of Pst
and Plt using analysis periods as defined
within the standard.
Simultaneously full analysis of voltage vari-
ations is performed, including the calcula-
tion of the maximum value dmax, the
difference between steady states dc, and
the change characteristic d(t).
The HA1600A incorporates both RS232,
and USB interfaces for use with a PC, and a
Centronics parallel interface for direct con-
nection to a printer.
The firmware of the instrument is stored in
flash memory and can be updated via
RS232 or USB as the requirements of the
standards evolve.
Digital interfaces and PC software
HA-PC Link Plus software is supplied with
the instrument to assist users in taking rou-
tine compliance measurements and archiv-
ing the results.
Data updating is continuous, permitting
real-time viewing on the PC.
Harmonics can be displayed on the PC as
tabular reports or as graphical histo-
grams.
Voltage and current waveforms.
The mains voltage purity has been restored
using an AC1000A. Compare this with the
uncorrected mains voltage shown in the
instrument illustration.
