Page 5: An Introduction To Impulse Testing With The Megapulse Series Tester
Section 1 An Introduction to Impulse Testing with the MegaPulse series tester The impulse test is designed to simulate impulse surges which occur in everyday life due to nearby lightning strikes, switching transients, and other high-frequency faults on the power distribution network. -
Page 6: Safety Techniques
Safety Techniques The high voltage circuit of the MegaPulse can be shut off at any time by turning OFF the rear power switch. Note that there are residual voltages inside the equipment that may take up to 5 minutes to bleed off to safe levels. - Page 7 Note that the peak amplitude of the measured output waveform is proportional to the voltage that is read on the front panel of the MegaPulse, but it will always be somewhat lower. This is because the meter on the MegaPulse is measuring the voltage on the main impulse storage capacitor (C1 in Figure 1). This voltage will intentionally dissipate to some extent before reaching the output leads.

Current duration (D) is defined (per ANSI/IEEE C62.41 and other standards) as the time between virtual origin and the time of the 50% pint on the tail. The virtual origin is the point where a straight line between the 10% and 90% points on the leading edge of the waveform intersects the I = 0 line. ∂ Indicates Models using Compliance West USA IEC 65 Switch.
