AC Power Source
Available in a choice of power levels ranging from 1250 VA to > 45,000
VA, the CTS Systems covers the complete range of single and three
phase products that require testing to conform with existing and
pending IEC standards. All iX Series AC sources meet IEC requirements
for low voltage distortion and offer arbitrary waveform generation,
precision measurements, and waveform analysis capabilities. Actual
AC Source voltage distortion is measured in real-time during the
harmonics test and any distortion that could affect the test results is
All iX Series based CTS systems support full compliance testing for
several IEC 61000-4 AC immunity standards as well (certain options
may be required, see ordering information for details).
Direct PC Data Acquisition
A high-speed digital signal processor based data acquisition system is
used to implement the required IEC compliance measurement system.
Direct access to the PC bus ensures a much higher data throughput
capability than typically found in single box IEC test systems that use
either the IEEE-488 instrumentation, USB, LXI or RS-232 bus to communicate
between the analysis instrument and the PC.
This high-speed acquisition system architecture stores raw data to the
hard drive and offers several features. It not only possesses the ability
to support future versions of test standards by merely installing new PC
software but it also greatly reduces the risk of product obscolescence as
test standards evolve. Furthermore, since the data is streamed to hard
disk in real-time, a complete data record is created each time which
may be used for audit purposes, data replay and further analysis or to
prove compliance to all the measurement requirements specified in
the test standard.
A special signal conditioning and isolation unit is used to provide
quick and easy connection between the AC source output and the
Equipment Under Test. This unit provides the required isolation, signal
conditioning and anti-alias filtering for the measurement system. The
equipment under test can be plugged in the front panel mounted
European style outlet (single phase systems only), or wired to a rear
panel mounted terminal block.
A key part of the CTS system is the IEC compliant power analyzer which
provides detailed information on both voltage and current. Measurements
of both harmonics and interharmonics are made in real-time
with no measurement gaps to fully conform to the latest revision of
the IEC 61000-4-7 test standard. AC source voltage and EUT power are
monitored continuously during the entire test. Voltage distortion and
current harmonic data is checked against IEC class limits for pass or fail
detection. Comprehensive test reports can be generated easily.
Test limits are retained in a password protected database and can be
updated if needed in the future without the need to change software.
Other software changes as a result of changing IEC harmonics standard
can be accomplished by simply installing new PC software. No
harmonics testing software resides in system firmware which would
require more costly field upgrades.
Flicker Reference Impedance
An IEC61000-4-15 compliant flicker meter is an integral part of the
CTS software. The required IEC 60725 compliant reference impedance
is implemented in the iX Series AC Source using programmable
output impedance. Programmable impedance offers improved accuracy
compared to a lumped reference impedance and the ability to
support different national standards without the need to switch out
lumped reference impedance hardware. A good example is testing
for compliance with the Japanese harmonics and flicker standard,
which requires different impedance values to be programmed as
compared to the European test standard.
Optionally, a lumped impedance compliant with IEC 60725 or the Z-test
specification of IEC61000-3-3 can be ordered for single or three phase
iX Series based CTS systems. For three phase CTS systems, a lumped
impedance option is recommended. The software can be configured
to use either impedance type during flicker testing.
