TTi has completely redesigned their low-cost harmonics, flicker and
power analyser, the HA1600. The new model, designated HA1600A, has a new
casing, a USB interface, and totally revised firmware to meet the
requirements of the latest revision to the harmonics and flicker
standards.
Since 1st January 2001, EN61000–3–2 has required the measurement of the
harmonic current produced by most electrical and electronic equipment.
Certain types of equipment also require testing to EN61000–3–3
(fluctuations and flicker testing). Compliance is a mandatory part of CE
marking. The HA1600A enables users to self certify their compliance.
The HA1600A has a 16 amps current capability and uses a shunt resistance
of 3 milliohms as defined by the standard. The large backlit LCD display
provides both graphical and numeric displays. It has an RS-232 interface
built-in as well as isolated monitor outputs which provide
re-constructed voltage and current signals.
It provides numerical and graphical analysis of mains harmonics from the
1st to the 40th to very high accuracy and can make compliance quality
measurements to EN61000–3–2. Harmonics can be displayed as lists or as
histograms with the compliance limits automatically calculated and
displayed. Simple pass/fail analysis can be done or detailed failure
information can be rapidly extracted. The fast update rate allows
real-time monitoring of circuit changes.
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 16A rms continuous.
As a fluctuations and flicker meter it can perform simultaneous full
analysis of voltage variations, including the calculation of the maximum
value dmax, the difference between steady states dc, and the change
characteristic d(t) as required by EN61000–3–3 and EN61000-4-15.
The HA1600A is available with range of power connectors to suit
different national standards. A printer interface is included for record
keeping and archiving, along with both RS-232 and USB interfaces for PC
connectivity.
The instrument is now supplied with HA-PC Link Plus software for
Windows. This is intended to assist users in taking routine compliance
measurements and archiving the results. Harmonics can be displayed on
the PC as tabular reports or as graphical histograms. The performance of
the PC does not affect the accuracy of the measurement results, and so
there is no need for the either the PC or its software to be covered by
a calibration certificate.
The HA1600A costs £1450 plus
vat in the U.K.
The approximate International price is $2700.
