Essay On Importance Of Emi Emc Testing

1116 Words5 Pages

Considering a general scenario that prevails globally, there is hardly any car which is driven without entertainment being an inherent part of it. At least there is music if not anything else. Since there is an increasing importance of in-car entertainment, automotive electronics is becoming more and more complex. In order to ensure the smooth functioning of this, electromagnetic interference (EMI)/electromagnetic compatibility (EMC) testing holds utmost importance. Importance of the testing The requirement of electronics in automotive does not end at the entertainment part only. Automotive electronics is critical for its use in all forms of communication and safety related requirements in vehicles these days. EMI/EMC test equipments play an essential role in ensuring a seamless …show more content…

This has been done in order to provide improved reliability and safety for users of electrical and electronic equipments in their vehicles. In an attempt to ensure compliance with these regulations, most automotive companies these days employ the services of a specialised test facility to perform the actual compliance tests required for EMI certification. The test facility might belong to an outside company (a “test house”) or to an in-house EMC department. A lot of effort is made towards designing the test equipments good enough to minimise as much EMI signatures as possible. Naresh Narasimhan, country marketing manager, Tektronix India says, “Most engineers employ good design practices to minimise the potential for EMI problems. It is common today to perform pre-compliance measurements during the design and prototyping stages to identify and address potential EMI issues before the product is sent out for compliance testing. These techniques reduce the risk that the product will fail the final full compliance at the test

    • Then the fault cable is tested to determine the type of fault, 18 KV is applied on each phase for 5 minutes, if the phase can carry this voltage, so this phase is good and no fault on it, if the phase cannot withstand this value of voltage, this means that the insulation is damaged and this phase is faulty, If one or more phase cannot withstand the 18 KV then these phases are faulty and the type of fault is short circuit due to breakdown of the insulation, but if the phases withstand the 18 KV applied but the current from the sending end not reach the other end, this means that there is an open circuit fault which is may be break in the conductor or the joint connecting the

    Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

     Create business flexibility The flexibility to adjust monitoring levels during a study if risks change, giving us the ability to adapt SDV review and frequency of onsite monitoring visits by supplementing oversight with centralised monitoring methods and remote monitoring visits. This activity is constantly changing during the trial and drives the business to flow.  Monitors:  Increase onsite working efficiency: During the on site visit, monitors can focus on addressing critical issues that cannot be resolved remotely. The centralised remote monitoring also save a lot of travel time and energy for the monitors, monitors can use bill their hours more efficiently to the projects since monitors no longer suffer from travel tiredness between visits.

    The TQM had two major weaknesses in the batch-and-queue system: First, the long time between the occurrence of a quality issue and its de-tection which impede the search for the root cause of the quality problem. Second, the inexistence of quality testing in the production line. Due to the missing quality control stations in line, defective parts were queued at the next process step in-stead of being sent to rework (Zone control). Daktronics decided to eliminate the quality problems by the “live testing” strategy. With the help of electronic, visual and standardized work instructions and checklists (in A3 format) including in-spections in line, testing of all parts was implemented to eliminate waste of de-fects (Jidoka and Poka-Yoke).
