Teseq ProfLine 2105 - 5 kVA Harmonics & Flicker Test System

Overview

System

ProfLine 2105 is an accurate and flexible 1-phase system designed to measure harmonics and flicker in accordance with IEC 61000-3-2 and IEC 61000-3-3. The system is supplied complete with a stable, accurate, programmable 5 kVA power source. The ProfLine 2105 system is therefore ready to measure and record any harmonics and flicker created by the EUT. A wide range of AC source systems are available from Teseq, please see ProfLine 2103, 2115, 2130, 2145 datasheets for suitable systems at different power levels or for 3-phase operation.

 Measurements are made using precision, no burden, active hall-effect current transformers connected via a dedicated cable to a multichannel fast Data Acquisition Card (DAQ) fi tted inside a PC. One voltage and three current measuring channels are used to make simultaneous measurement of both current and voltage. Calculations are made using dedicated Teseq software (WIN 2100) to determine harmonics (classes A-D), inter-harmonics, fl icker, dc, dt, dmax, Pst, Plt, inrush current and 24 x dmax.

Impedance

Measurement of fl icker requires a fi xed, stable source impedance as specifi ed in IEC 61000-3-3 (0.24 Ω + j0.15 Ω in the line and 0.16 Ω + j0.1 Ω in the neutral). The precision power source (NSG 1007-5) supplied as part of the system is able to accurately simulate this impedance by careful control of the relationship between voltage and current. This eliminates the need for a costly physical impedance. However, physical lumped impedances are available from Teseq, see options list.

Power quality measurement

 The power source (NSG 1007-5) supplied as part of the ProfLine 2105 system is able to perform tests in conformance to a number of immunity standards. IEC 61000-4-13 (immunity to harmonics and interharmonics), IEC 61000-4-14 (voltage fluctuations), IEC 61000-4-17 (ripple on DC) and IEC 61000-4-28 (variation of power frequency). Additionally it can also perform pre-compliance testing to IEC 61000-4-29 (voltage dips, interrupts and variations on DC supply) and IEC 61000-4-11. With the addition of further options IEC 61000-4-8 (power frequency magnetics) and fully compliant IEC 61000-4-11 (voltage dips, interrupts and variation on AC supply) can be implemented.
