Section 1 Introduction and Safety An Introduction to Impulse Testing with the MegaPulse PF 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. Impulse testing is the fundamental method for empirical verification of the adequacy of insulation. -
Page 8: Safety Techniques
Safety Techniques The high voltage circuit of the MegaPulse D8-PF can be shut off at any time by turning OFF the rear power switch. Always press TRIGGER to discharge the tester before turning OFF. The MegaPulse tester is provided with a digital VOLTAGE ADJUST knob on the front panel. This voltage setting should always be confirmed by pressing the VOLTAGE ADJUST knob before starting any test. -
Page 9: Using The Megapulse Pf Impulse Tester
Using the MegaPulse PF Impulse Tester The impulse test involves high voltage and caution should be exercised when using the tester. The RETURN lead is referenced to building ground when properly connected. However, both the OUTPUT and RETURN leads must always be treated as Hazardous whenever the power switch of the MegaPulse is in the ON position. The MegaPulse impulse tester generates the impulse waveform only;... -
