Research is largely concentrated on high voltage measurement and metrology. This project concentrated on practical issues: distribution transformers and protective spark gaps. The project was supervised by the following expert group: Jarmo Elovaara from IVO Power Engineering Oy, Juha Sotikov from Finnish Electricity Association and Esa Virtanen from ABB Transmit Oy as well as Martti Aro, Matti Karttunen and Veikko Palva from Helsinki University of Technology. Abstract Distribution transformers in rural networks have to cope with transient overvoltages, even with those caused by the direct lightning strokes on the lines. In Finland, the 24 kV network conditions, such as wooden pole lines, high soil resistivity and isolated neutral network, lead into fast transient overvoltages. The distribution transformers (< 200 kVA) have been protected and a major part is still protected using protective spark gaps. The protection characteristics of different spark gap types were studied widely using improved measuring techniques.

  • Residual Resistance Simulation of an Air Spark Gap Switch
    Residual resistance simulation of an air spark gap switch. V. V. Tikhomirov, S.E. Siahlo∗ February 27, 2015 Research Institute for Nuclear Problems, Belarusian State University, Bobruiskaya 11, 220030 Minsk, Belarus Abstract The numerical simulation of an air spark gap has been carried within two theoretical models. The kinetic one [1] allowed us to calculate time dependencies for the residual resistance (0.2 - 0.4 Ohm for our selection of a circuit parameters), the spark gap channel width, the electron number density, the mobility, the conductivity, the ionization degree, the magnetic field in the discharge channel, the channel inductance and the electron drift velocity. Simulating a real circuit and taking into account a spark gap residual resistance demonstrates good agreement of both models with the experimental data, while that without taking into account this resistance overestimates the maximal current in the circuit by approximately 5%. 1 Introduction The high-voltage spark gap switches are essential elements of the circuits containing magneto- cumulative generators, capacitive and inductive energy storages, electro-explosive circuit break- ers etc. Very frequently spark gaps affect sufficiently the operation of the circuits and one cannot satisfactorily describe main elements functioning in the absence of a quantitative model of the processes occurring in the spark gaps. This article is devoted to the comparison of two such models considering a real circuit, where the influence of a high-voltage spark gap results in a decrease of the maximal current for about 5%. We review in detail the model [1] based on the time dependent method for the electron number density simulation in the air spark gap channel using an anisotropic solution of the kinetic equation [2].

Typically, however, such devicesfail at a voltage well below that expecteddue to a poorly understood,surface-related breakdown process.In this letter we present empirical results which show that such breakdown of long silicon pf-i-n+ devicescan be inhibited by the application of weak visible or near-infrared illumination.

    Two-Electrode Spark Gap Preamble INTRODUCTION PRINCIPLES OF OPERATION The range of two-electrode spark gaps offered by e2v A simple two-electrode spark gap is shown in Fig. 1. At low technologies comprises hermetically sealed gas-filled switches voltages the gap is an insulator. As the voltage increases, the available with DC breakdown voltages from 400 V to 50 kV. few free electrons (present in the gap as a result of cosmic Two-electrode spark gap applications include voltage surge radiation and other ionising effects) are accelerated to higher protection, lightning protection, single-shot pulse generators, velocities, until they are able to ionise atoms of the gas filling. high energy switches and turbine engine ignition circuits. This leads to an avalanche effect as the additional electrons produce further ionisation and as the current builds up, the PRINCIPAL FEATURES voltage falls (see Fig. 2). There is a range of current over which emission from the cathode takes the form of a glow discharge * No Standby Power Consumption and the voltage is almost constant. * Consistent Breakdown Voltage * High Current Capability GAS FILLING MAIN ELECTRODE GAP 4169B * Fast Switching * Rugged and Reliable over Temperature Range * Lightweight TWO-ELECTRODE SPARK GAP SELECTION When considering the choice of spark gap, the following factors should be taken into account: * Application * Peak Current and Waveform * Coulombs per Shot INSULATOR * Maximum Repetition Rate * Main Gap Voltage Fig. 1.

  • PS/6772 It Should Be Noted Here That If, for Any Reason, This Feedback
    14 ins-SI/Note MAE/68~5 5.10.1968 K66 KICKLJ PROJECT C. Carter Introduction This note describes the supplies and associated equipment used to power the FK66 Kicker Magnet. A pulse forming network consisting of two low loss 16 coaxial cables in parallel is charged from a H.V. power supply. At the desired maximum voltage the stored energy in the cables is switched into the magnet which is also matched by a triggered spark gap. As the magnet is a balanced four terminal network? both positive and negative supplies are needed, as are the associated pairs of cables and spark gaps. A change—over switch selects the direction of ‘kick'. A choice of 3 bunch or 6 bunch ejection required two pairs of charging cables (termed the ‘short' and 'long' cables), and thus four individual power supplies (Fig. 1). General description 2 The four similar power supplies are all housed in an oil filled tank. The control element in each is a ML8495 tube, which is held normally off by a rectifier A.C. voltage obtained from a power oscillator. A ramp function generator modulates this oscillator to turn the tube on, which charges the cables (Figs. 2 and 3). A voltage divider chain on the output is used for measurement and also as a reference point for comparison with the applied ramp function. PS/6772 It should be noted here that if, for any reason, this feedback 100p is broken9 control of the series tube ML8495 will be lost resulting in full output voltage on the cables.

  • Design of a Resonant Soft Switching Power Supply for Stabilized Dc
    DESIGN OF A RESONANT SOFT SWITCHING POWER SUPPLY FOR STABILIZED DC IMPULSE DELIVERY by Andrew H. Seltzman A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science (Electrical Engineering) at the UNIVERSITY OF WISCONSIN-MADISON 2012 APPROVED By Adviser Signature: ______________________________________ Adviser Title:_________________________________________ Date:__________________ i Abstract This thesis addresses the issues involved in the design and construction of a multi- phase resonant switching power supply for delivery of a high voltage, high current stabilized DC impulse. Such a power supply may be used in place a pulse forming network (PFN) to drive a high power klystron amplifier, which typically requires voltages near -100kV at 10s of amps of current. Unlike an LC PFN, a switchmode power supply (SMPS) allows greater control over pulse duration while still allowing generation of longer duration pulses on the order of 10ms with constant output voltage by use of feedback regulation. Specifically, the thesis documents the results from the design of a loosely coupled boost transformer with a parallel LC resonator on the secondary, a microcontroller based control system for feedback stabilization and techniques of harmonic mitigation to reduce switching noise on the output waveform. iii Acknowledgements I would like to thank Giri Venkataramanan, Paul Nonn, Bob Ganch, Jason Kauffold and Jay Anderson for assisting with this project.
