AIF 503S1 Flicker Impedance 3-phase 32A

for Harmonics & Flicker testing

AIF 503S1 is a three-phase flicker impedance designed for testing

Harmonics and Flicker.

The specifications of the two flicker impedances Zref and Ztest are as

per EN / IEC 61000-3-3 / -11.

The AIF 503 offers space to accommodate the 3-phase Harmonic and

Flicker analyser DPA 503.

The Flicker Impedance AIF 503 S1 is designed for Flicker and Harmonic test according IEC 61000-3-3 and IEC 61000-3-11 with built in Zrefand Ztest.

Reference Impedance ZrefZref is a conventional impedance as specified in IEC 61000-3-3 with the impedance values in accordance with IEC 60725.

Test Impedance ZtestThe test impedance Ztest is lower than Zref and used for 3-phase or single phase equipment intended to be connected to public low-voltagedistribution systems having a service current supply with a capacity ≥ 100A.

Block diagram

The AIF 503S1 is controlled from the DPA 503.

The DPA 503 measures the voltage and current for harmonic andflicker analyzing. The flicker impedance Zref / Ztest is bypassed for theharmonic measurement.

The system is operated from the computer with the windows softwareISMDPA.
