XY-Capacitor Surge Test (IEC60384-14)

A full automatic Surge test for X/Y-Capacitors for eight samples up to 12kV (IEC60384-14)

Procedure:
"Each individual capacitor shall be subjected to a maximum of 24 pulses of the same polarity. The time between impulses shall be not less than 10s. If any three successive impulses are shown by the monitor to have had a waveform indicating that no self-healing breakdowns or flashovers have taken place in the capacitor then no further impulses shall be applied and the capacitor shall be counted as passed. If all 24 impulses have been applied to the capacitor and three or more of them are of waveform indicating that no self-healing breakdowns or flashovers have taken occurred then the capacitor shall be counted as passed, but if less than three impulses are of the required waveform then the capacitor shall be counted as a defective."


Waveform monitor:
An oscilloscope compares the waveshape with a reference waveshape taken from a good sample. If there is any amplitude difference greater than 10% the capacitor has failed. Further the peak value of the pulse has to be within +/-10% and the duration within +/-20%.

Sample 2 :all pulses have passed
Sample 3 : The capacitor is broken at the second pulse.The oscilloscope shows an full short circuit.The test on this sample is stopped.
Sample 4 :The first pulse shows an self-healing.
The following pulses are o.k.
Sample 5 : At this sample there were no 3 good pulses in a sequence, so all 24 pulses were need to test. Because more than 3 are good, the sample has passed.

Insulation Test on a 36-pin Connector

Files : APP31.htm

On a 36-pin connector all neighbouring pins have to be tested with an 6kV 1.2/50us pulse of both polarities.
The full automatic test set-up uses a pulse generator, an automatic switching box and the TEMA software.
The interval between two pulses is about 10sec and the overall time for all pins about 15min. The insulation test has failed if any current higher than 100Apeak is measured. This is detected with the internal peak measurement of the generator.

The protocol is a HTML-file just as generated by TEMA protocol engine.

If you want to know more about this test then install the TEMA Version which is free for download on the emc-partner webpage www.emc-partner.ch . You find this example as file "Examples/more/connector-test.seq". The TEMA Software has a demo-mode with a built in simulator for all EMC-PARTNER generators so that you can run an edit the test just as with the real MIG1203 Insulation tester.

IEC 1000-3-2 : Harmonics Emission Measurement on a Personal Computer Monitor

Files : APP20-en.htm
German Version : APP20-ge.htm

We tested several PC monitors of different size from different manufacturers. The measured power consumption ranged from 40W to 100W. Monitors with a rated active power lower than 75W do not need to be tested, the ones above are class-D.
The power consumption depends on the brightness of the displayed picture. The difference between a black and a white screen is as much as 20W.
All tested monitors with an active power greater 75W are far over the limits for class-D. The example here shows a typical monitor. ( Phillips 17B )
Some tested television receivers show similar results. In Annex C of IEC1000-3-2 the test conditions for television receivers are defined.

IEC 1000-3-2 : Harmonics Emission Measurement on a Laser Printer.

Files : APP29-en.htm

A 400W heater inside the printer switches on every 16 seconds for about 2 seconds. For the evaluation of Pmax the active power is filtered with an 1.5 second filter. Pmax reaches about 325W. For class-D all harmonic current limits are related to that value..

IEC 1000-3-2 : Harmonics Emission Simulation.

Files : APP210-en.htm

Simulation of a 17"-PC-Monitor

Basis for this simulation is a real measurement on a PHILLIPS 17"-Monitor (see example APP20 "monitor-crt17inch").

The equivalent circuit is already evaluated by the ANASIM software.
- the blue curve shows the current of the equivalent circuit.
- the black curve shows the current of the original monitor.

The harmonic currents are far over the limits for class-D.
By increasing the series resistor it is possible to decrease the harmonics under the limits. Try 40ohm.

IEC 1000-3-3 : Flicker Simulation for an Industrial Blower

 A fan of about 2000VA is switched on for 15 seconds every 30 seconds.

A high start-up current of more than 200% causes a high Flicker Level.. To reduce the Flicker, the start-up current has to be reduced, e.g. with an electronic soft-start device.
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. Here the values are written into a table.

Files in english:
APP23-1-en.htm :
shows the simulated Flicker without soft-start.

Files in german:

The resulting Flicker Levels are evaluated by simulation only. Input is the estimated inrush-current shape of the blower.

IEC 1000-3-3 : Flicker Simulation for a Heater Group

Two heaters of 750W each have to be switched on for 5 seconds every 10 seconds.
The switching causes a Short-term Flicker (Pst) of higher than 1.00.
To reduce the Flicker, the heaters can be switched at slightly different times.

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. Here the values are written into a table.

Files in english :

The resulting Flicker Levels are evaluated by simulation only. Input is the power versus time.

IEC 1000-3-2 : Amendment 14.

Files : APP211-en.htm

HARCS Software is in accordance with EN 61000-3-2 published 1995 and EN 61000-3-2 plus A14 published January 2001.
Industry has been lobbying for a long time for publication of essential changes to EN 61000-3-2 which gives a presumption of conformity to EMC directive. Under "Common modification on EN A14:2000 the standard has been published in the OJEC reference C 359 and OJEC date 2000-12-14. With this publication, it is ensured that from the first of January 2001 the relevant products will have the possibility of choice to benefit from the presumption of conformity to the essential requirements of the EMC directive by complying either with the specification laid down in the EN, or those of the EN as modified by its amendment 14 and this up to the first of January 2004. After this date only the latter configuration will apply. This will be welcomed by many industrial circles and manufacturer associations.
