EMC Partner DOW-CG1-S-F-I Slow/Fast Damped Oscillatory Wave Generator

IEC 61000-4-10 relates to the immunity requirements of equipment, only under operational conditions, to damped oscillatory magnetic disturbances related to medium voltage and high voltage substations. This standard is intended to demonstrate the immunity of equipment when subjected to a damped oscillatory magnetic field related to the specific location and installation condition of the equipment (e.g. proximity of equipment to the disturbance source). The scope of IEC 61000-4-10 establishes a common and reproducible basis for evaluating the performance of electrical and electronic equipment for medium voltage and high voltage substations when subjected to damped oscillatory magnetic fields. IEC 61000-4-10 defines: Recommended test levels Test equipment Test set-up Test procedure The damped oscillatory magnetic field is generated by the switching of high voltage bus-bars by isolators. The test is performed by applying a damped oscillatory magnetic field (sinusoid waves) of defined strength to the equipment to be tested.   Waveform Specification Low Frequency High Frequency Oscillation frequency 0.1 MHz 1 MHz Decay rate 50% of the peak value after 3/6 cycles 50% of the peak value after 3/6 cycles Repetition rate ≥40 Hz ≥400 Hz Test duration 2 s 2 s   Test Level Damped Oscillatory Magnetic Field strength A/m (peak) 1 Not defined 2 Not defined 3 10 4 30 5 100 x special Advanced Test
