In the previous video I verified that my simple sphere gap measurement setup is quite satisfyingIn this video I use the method to measure the pulsed voltage generated by my ignition coil Actually to measure a high voltage pulse we can use a highfrequency high voltage o’scope probe like North Star PVM seriesBy using oscope we can obtain the whole waveform.

SPHERE GAP Measurement of High Voltage Module 3

Sphere gap method of Voltage measurement Measurement of the potential energy of an electric field to cause an electric current in an electrical conductor Voltage is the difference in electrical potential between two points of an electrical or electronic circuit A uniform field spark gap will always have a spark over voltage within a known tolerance under constant atmospheric pressure.

Research Article Peak Voltage Measurements Using Standard

You may have heard that the voltage breakdown of air is about 30 kV/cm This is referred to this sphere gap method In fact if the electrode is not sphericallyshaped ie pointed tip the electrical potential becomes very concentrated As a result a 30 kV voltage can generate spark at distances more than 1 cm.

Sphere Gap Radiology

PDF fileprotected against over voltages Sphere gap method is the one of the standard method for measurement of peak values of AC DC voltages in high voltage circuits The gap distance between the spheres should not exceed the radius of the sphere In short duration of time we can measure the breakdown voltage using this method Sphere electrodes are.
