Introduction
The PCTS pre-compliance harmonics
and flicker test system provides a cost
effective solution for testing products
to EN61000-3-2 harmonics, and
EN61000-3-3 Flicker standards during
internal product qualification and de-
velopment stages. Using line AC power
from 100 - 240 Vac 50 Hz, the PCTS
uses proprietary software algorithms to
compensate for line distortion. Hence,
test results will be virtually identical to
those that will be obtained with a full
compliance test system. This ensures
that results are consistent and repeat-
able, regardless of prevailing line con-
ditions.
For flicker analysis, the use of a so-
phisticated dual channel measurement
technique compensates for the lack of
the IEC 725 impedance and dynami-
cally calculates the correct flicker re-
sults. Therefore, test results of the
PCTS are within a few percent of those
that will be obtained by a certified full
compliance test system. Thus the
PCTS can be used to check EUT’s
before submitting them to a test lab or
for periodic verification of product com-
pliance in a production environment.
Modular Architecture
The PCTS system utilizes an easily
upgradeable modular approach. The
signal conditioning unit converts volt-
age and current into low level signals
that are routed to the AC power ana-
lyzer card that is installed in the user’s
PC. This approach is extremely cost
effective, and only requires the user to
plug the signal conditioning unit into a
wall outlet. The EUT is then plugged
into the signal conditioning unit, which
can be placed under a printer or a
desktop style PC.
50 Hz AC Line Operation
Typical harmonics and Flicker compli-
ance test systems such as the Califor-
nia Instruments CTS series utilize a
programmable AC power source. The
PCTS however relies on the available
50 Hz AC line power. Note that 60 Hz
line power with different voltage levels
may cause harmonics spectra to differ
substantially. Moreover, 60 Hz power
distribution systems also have a lower
impedance, affecting Flicker calcula-
tions. Thus, it is advised to use a fully
IEC compliant CTS Series system un-
der these conditions.
The included PACS signal condition-
ing unit (Power Analysis and Condition-
ing System) provides the required sig-
nal isolation and scaling for the PC
based acquisition system. A high
speed sampling system records and
processes all relevant data and pro-
duces a real-time display of voltage,
current and harmonic content.
The elimination of the AC power source
and the use of a PC based measure-
ment system greatly reduces the ac-
quisition cost of the PCTS compared
to traditional harmonics and flicker test
systems.
