Generation of Impulse Current Generator Output Waveform: Lightning discharges involve both high voltage impulses and high current impulses on transmission lines. Protective gear like surge diverters have to discharge the…
Measurement of High Voltage and Currents Articles: Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter…
Generation of High Voltage and Currents Articles: Different Types of High Voltages: In the fields of electrical engineering and applied physics, Different Types of High Voltages (d.c., a.c,, and impulse)…
Grounding of Impulse Testing Laboratories: An earth or ground system means an established stable .reference potential normally taken to be zero. There are three types of Grounding of Impulse Testing…
Impulse Voltage Test System: It is extremely difficult to control and adjust the Impulse Voltage Test System wave shapes for different load conditions as in the case of large capacitive…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
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…
Multistage Impulse Generator Circuit: In the early discussion, the generator capacitance C1 is to be first charged and then discharged into the wave shaping circuits. A single capacitor C1 may…
