TTi HA1600A - AC Line Harmonics Analyzer including Flicker Analysis

The HA1600A is a high speed, high accuracy 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 connector. 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, Frequency and Inrush current.
 

The large display can show multiple parameters simultaneously as well as graphical representations of voltage and current waveforms.

Dual 16 bit Analog to Digital converters continuously sample both voltage and current and give a wide dynamic range. A fast Digital Signal Processor gives the performance needed for continuous real-time analysis of the data. Advanced algorithms yield accurate results, using extended precision or floating-point arithmetic wherever necessary.
 

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 purpose mains analyser.

The unit 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.

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 connection.

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 measurements using a normal mains supply and is capable of full compliance measurements to EN61000-3-2 in conjunction with a suitable power source such as the AC1000A.
 

Compliance-quality Flicker Meter

The HA1600A can operate as a compliance quality flicker and fluctuations meter in conformance with EN61000-3-3 and EN61000-4-15.
 

A current measurement method can be used, as an alternative to voltage measurement, thus eliminating the need for a reference impedance. Flicker severity is measured in terms of Pst and Plt using analysis periods as defined within the standard. Simultaneously full analysis of voltage variations is performed, including the calculation of the maximum value dmax , the difference between steady states dc , and the change characteristic d(t).
 

Digital interfaces and PC software

The HA1600A incorporates RS232, USB interfaces for use with a PC, and a Centronics parallel interface for direct connection 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.

HA-PC Link Plus software is supplied to assist users in taking routine compliance measurements and archiving the results. Data can either be in the form of a single report or can be continuous, permitting real-time viewing on the PC. Harmonics can be displayed on the PC as tabular reports or as graphical histograms.
