A Marx Generator is an electrical circuit consisting of capacitors, resistors, and spark gaps arranged in a ladder structure capable of producing high voltage impulses (which result in sparks) by first charging the capacitors in parallel and then discharging them in series. A Marx Generator is an electrical circuit consisting of capacitors, resistors, and spark gaps arranged in a ladder structure capable of producing high voltage impulses (which result in sparks) by first charging the capacitors in parallel and then discharging them in series.

The impulse generator can beextended for the generation of higher peak values (by adding of some stages) or for thegeneration of other wave shapes (by adding resistor s and or other external circuits). Simulation and Modelling of Lightning Impulse Voltage Generator using Marx Circuit” in partial attainment of the requirements for the honour of Bachelor of Technology in Electrical Engineering at National Institute of Technology, Rourkela is a genuine work carried out by him

N Impulse generator is an electrical apparatus which produces very short duration high-voltage or high- current surges. Impulse is a signal of very high magnitude and very small duration. This impulse is passed through the trans- former for the insulation testing. Impulse voltage generation is circuit, multi-stage generators operate over a much greater range of voltage for given gap spacings in the various stages than is the case with the conventional circuits.

In a super Marx generator, the Marx generators also assume the role of the resistors in the original Marx circuit. With a voltage of 10 9 Volt and a discharge current of 10 7 Ampere, the generation of a circuit of a single stage impulse generator is shown in Fig.2, where the capacitor Cs is charged from a dc source until the spark gap G breaks down. The voltage is then impressed upon the object under test of capacitance Cb. The waveshaping resistors Rd and Re control the front and tail of the impulse voltage available across Cb respectively. Overall, the wave shape is determined by the values

Impulse generator circuits Combination-wave generators Expanding single output generators to multiple output Generator variants 2. Types of impulse generator Impulse generators can be classified into three types: 1. Generators with a defined voltage waveform typically used for high-voltage insulation testing 2. Generators with a defined current waveform typically used for high-current Control System Design to Automate 100KV Impulse Generator Talha Iqbal, Hasan Ul Banna Abstract— This paper is basically the practical study of converting manually operated impulse generator to automatic generator. Ever since 1970 (when the High voltage lab of UET Lahore, Pakistan was constructed) most of the equipment in this lab has been operated manually. In this Lab, we have two impulse

stage Marx generator which generates the impulse voltage for 16th NATIONAL POWER SYSTEMS CONFERENCE, 15th-17th DECEMBER, 2010 523 Department of Electrical Engineering, Univ. College of Engg., Osmania University, Hyderabad, A.P, INDIA. This thesis describes the creation of a simulation circuit to match the output of a Marx type Impulse Generator. The goal was to estimate the stray capacitance and insert that capacitance into the simulation circuit to effectively produce an output similar to that of the generator. An actual three-stage impulse generator was used as the base.

circuit of a single stage impulse generator is shown in Fig.2, where the capacitor Cs is charged from a dc source until the spark gap G breaks down. The voltage is then impressed upon the object under test of capacitance Cb. The waveshaping resistors Rd and Re control the front and tail of the impulse voltage available across Cb respectively. Overall, the wave shape is determined by the values The operation of the circuit of FIG. 1 is somewhat similar to that of the conventional Marx generators in the sense that when switch 18 is open capacitors 13 are effectively charged in parallel from source 19 and when switch 18 is closed they are discharged in series with the output circuit. When switch 18 is open, current from source 19 will charge capacitor 12 through inductor 20 and the
