IEC 1000-3-3 : Flicker Simulation for an Heater Group
The "ANASIM" Software with the Flicker simulation offers the possibilities to calculate in advance the Flicker of a circuit. Today no other software can be found on the market for Flicker simulation. The "ANASIM" software is a sophisticated tool for design and test engineers.
The basis for the simulation is the time function of the apparent input power and the power factor of the EUT.

First Step:

Choose Options / Simulation / SIM to change to simulation mode

Second Step:

Enter the Power versus Time values into the table

Last Step :

Run the Flicker test as usual and you get the results like or a real measurement. Below you see the protocol as automatically generated in HTML mode.

Plt             Long term Flicker over all Pst cycles

For every Pst-cycle:

Pst             Short term Flicker
P50s            Flicker level reached during 50% of the test time
P10s            Flicker level reached during 10% of the test time
P3s             Flicker level reached during 3% of the test time
P1s             Flicker level reached during 1% of the test time
P0.1s           Flicker level reached during 0.1% of the test time
Fli(max)        Maximum Flicker level during test time

General :
- The values marked with "***" are actual values which could vary
  during test-time and are taken at the time of protocol printout.

Notes
1500W Heater Group
------------------
Two heater of 750W each are switched on every 10 second for 5 second.

The resulting Short-Term Flicker (Pst) is higher than 1.00
