Impulse measurements using Multiple Shield Enclosures and Signal Cable: Multiple Shield Enclosures - It is essential that leads, layout, and connections from the signal sources to the CRO are to be…
Rogowski Coil Integrator Design: If a Rogowski Coil Integrator Design is placed surrounding a current carrying conductor, the voltage signal induced in the coil is vi(t) = M dI(t)/dt where…
Low Voltage Arms for Voltage Divider: Low Voltage Arms for Voltage Divider - The mode of connection and the layout arrangement of the secondary arm of the divider is very…
Mixed RC Potential Divider: Mixed RC Potential Divider use R-C elements in series or in parallel. One method is to connect capacitance in parallel with each R′1 element. This is…
Potential Dividers for Impulse Voltage Measurements: Potential or voltage dividers for high voltage Impulse Voltage Measurements, high frequency a.c. measurements, or for fast rising transient voltage measurements are usually either…
Tripping of Impulse Generator: In large impulse generator, the spark gaps are generally sphere gaps or gaps formed by hemispherical electrodes. The gaps are arranged such that sparking of one…
Streamer Theory of Breakdown in Gases: Townsend mechanism when applied to breakdown at atmospheric pressure was found to have certain drawbacks. Firstly, according to the Townsend theory, current growth occurs…
Gate Firing Converters: The firing pulse control unit constitutes the heart of any thyristor power conÂverter. The Gate Firing Converters required by the thyristors are often derived from the digital…
