Flash X-ray generation has been carried out at KALI 30 GW system at 500 kV, 20 kA for 80 ns pulse duration. This Flash X-ray source was used to study the penetration of X-rays through the Stainless Steel 304L blocks of various thicknesses. X-ray dose measurement was done using optically stimulated luminescence dosimeters. These X-ray penetration experiments were repeated with image plates to get a...
The vacuum interrupter is extensively employed in the medium voltage switchgear for the interruption of the short-circuit current. The voltage across the arc during current interruption is termed as the arc voltage. The nature and magnitude of this arc voltage is indicative of the performance of the contacts and the vacuum interrupter as a whole. Also, the arc voltage depends on the parameters like...
A vacuum interrupter utilises a magnetic field for effective arc extinction. Based on the type of field, the vacuum interrupters are classified as radial or axial magnetic type of vacuum interrupters. This paper focuses on the axial magnetic field type of vacuum interrupters. The magnitude and distribution of the axial magnetic field is a function of the design of the contact system. It also depends...
