The MegaPulse tester provides impulses up to 4.46kV peak 1.7kΩ load. The tester has positive and negative waveform delivery via a front panel button. Tester impedance is 39ohms. The MegaPulse tester has voltage waveform 500µs rise time, 3.4ms duration and up to 4.46kV on a 1.7kΩ load.

The MegaPulse impulse tester generates the impulse waveform only; it does not determine Passing or Failing results. It is the operator’s responsibility to monitor the output waveform and determine Passing or Failing results. In monitoring the impulse waveform, consider the following points: The Impulse waveform is high voltage and high frequency (short duration). Always ensure that the measuring instrument (usually an oscilloscope with a high-voltage probe) is rated for the voltage involved, and that the frequency response of the instrument and probe are capable of measuring the output waveform of the MegaPulse Impulse Tester. A measuring instrument or probe with a low frequency response will result in erroneous readings that could be mis-read.

Determination of Passing and Failing results can prove difficult. To obtain the most accurate results, it is generally necessary to perform multiple impulse tests on a few different test samples (that have adequate insulation to pass the impulse test). Take note of the impulse waveshape, amplitude, and duration. Also note how much variance there is in the waveshape from test to test. Also (if possible), perform impulse testing on some test samples that are known to have inadequate (or damaged) insulation. Take note of the impulse waveshape, amplitude, and duration, when an insulation breakdown occurs.
