Hello, In the process of evaluating replacement equipment that meets the requirements of IEC 61000-3-2:2000/IEC61000-4-7 and IEC61000-3-3+A1/IEC61000-4-15, I put together a small Electronic Load based on an old HP/Agilent verification process. Circuit = Relayand bypass switch to Lamp Dimmer with 200W bulb across line connected to - 3 -Glocoils in parallel with 2 Glocoils to other side of line.Parts availiability limited voltage to 120V. Well , I gathered three vendors equipments, performed a bunch of tests, with the following results: Stationary Harmonics - All very Close Fluctuating harmonics - All over the place Flicker,- With Lamp Dimmer and 200W Bulb - Large differences between Test Equipment, consistently the same. Since these results are all over the place I would like to set up a quick Round-Robin in the Sacramento/Bay Area , CA the first week of March. For scheduling I would bring the unit around to the Test laboratories with different Test Equipment that meets the "NEW" requirements and then schedule the others. Tests would consist of : Stationary Harmonics Fluctuating Harmonics Flicker with Dimmer and bulb - 10 Min Flicker without - 10 Min Thanks, Ken Hall Hewlett Packard 916-785-4819
