The
TTi HA1600A mains and harmonics analyser has been updated to include
a full implementation of the two alternative special assessments for
Class C Discharge Lighting equipment below 25 W, as specified in
EN61000-3-2.
The
requirements of this standard include the measurement and display of
the phase angles where current conduction starts and stops, and the
phase angle of the last peak of the current waveform in each
half-cycle. It also provides for a ‘no limits below’ threshold in
Class C (standard lighting equipment) measurements, with a default
value of 25 W.
In
addition to the standards changes, TTi has also improved the way in
which the phase angle is reported for the phase of the peak current.
This gives a more useful value with real-world distorted mains
waveforms (when the actual peak is often beyond 105°). Phase is now
relative to the mid-point of the two zero crossings of the voltage
waveform rather than the actual peak of the voltage waveform. If the
mains voltage is an undistorted sine wave, the result will be the
same.
Printed reports produced either directly from the instrument or
through the new release of the HA-PC Link software are enhanced to
include the extra information and assessments.
The
new firmware for the HA1600A is shipped with all new units. The
update is available to existing users as a free download on the
product support pages on the TTi web site:

The
HA1600A is a fast, easy-to-use mains and harmonics analyser with a
large high-resolution graphical display. Intended primarily as a
dedicated harmonics and flicker analyser for compliance quality
measurements, it can also be used as a general-purpose mains
analyser. The HA1600A is capable of continuous real-time analysis of
both voltage and current. As a general purpose mains analyser it can
measure watts, VA, Vrms, Vpk, Arms, Apk, crest factors, THD, power
factor, frequency and inrush current with a rating of 16 A RMS
continuous.
