ΕΠΙΔΡΑΣΗ ΤΗΣ ΜΟΡΦΗΣ ΘΕΤΙΚΗΣ ΚΡΟΥΣΤΙΚΗΣ ΤΑΣΗΣ ΚΑΙ ΤΩΝ ΠΑΡΑΜΕΤΡΩΝ ΤΟΥ ΔΙΑΚΕΝΟΥ ΣΤΗΝ ΕΞΕΛΙΞΗ ΤΗΣ ΔΙΑΣΠΑΣΗΣ ΣΕ ΜΙΚΡΑ ΔΙΑΚΕΝΑ ΑΕΡΑ

THE INFLUENCE OF THE IMPULSE FORM AND PARAMETERS ON THE BREAKDOWN VOLTAGE OF ROD-PLANE AIR-GAPS BETWEEN ONE AND FIFTY FIVE CENTIMETERS WAS INVESTIGATED A 12 MM CYLINDRICAL ROD WITH THE FOLLOWING TERMINATION: - 30 DEGREE CONE, - HEMISPHERE, - SQUARE-CUT AND IMPULSE VOLTAGES OF THE FOLLOWING FORMS: 1/36 MS, 2/36 MS, 1/280 MS, 2/280 MS, 15/280 MS, 20/280 MS, 60/350 MS, 1/1800MS, 2/1800 MS, 15/1800 MS, 20/1800 MS, 60/1800 MS, 120/1800 MS, 180/1800 MS, WERE USED. THE MAIN CONCLUSIONS OBTAINED ARE THE FOLLOWING: - A DEPENDENCE OF THE AMPLITUDE OF THE IMPULSE BREAKDOWN VOLTAGE FROM THE FRONT OF THE IMPULSE IS OBSERVED FOR SPECIFIC LENGTHS OF THE GAP. - FOR THE SAME FRONT OF THE IMPULSE, THE TAIL ALSO AFFECTS THE AMPLITUDE OF THE BREAKDOWN VOLTAGE. - IN ADDITION TO THE AMPLITUDE, THE FORM OF THE IMPULSE AND THE GEOMETRICAL PARAMETERS OF THE GAP, HAVE A CONSIDERABLEEFFECT ON THE STANDARD DEVIATION OF THE BREAKDOWN VOLTAGE. - FOR SPECIFIC COMBINATIONS OF IMPULSE SHAPE AND GAP PARAMETERS THE BREAKDOWN PROBABILITY DISTRIBUTION DEVIATES FROM THE NORMAL AND FOLLOWS THE WELL KNOWN INVERTED-S. - FOR GAPSLONGER THAN 30 CM THE MEAN BREAKDOWN GRADIENT IS AROUND 5 KV/CM WHILE FOR SHORTER GAPS MAY BECOME SUBSTANTIALLY HIGHER.
