Whenever an electrical circuit carrying considerable energy is opened in oil, gases are generated. These expand and rise, and tend to force the oil out of the containing vessel. They also form with air explosive mixtures, and either explode, or burn for a considerable length of time when ignited. It is important, therefore, that oil circuit breakers be provided with ...

Pulse voltage measurement techniques include crest voltmeters, voltage dividers, capacitive probes, electro‐optical transducers, and reflection attenuators. Spark gaps can be used for the measurement of crest values of voltage pulses from 1 kV to 2.5 MV. Good irradiation and short gap spacing are the key requirements of spark gaps for measurement of crest voltages of nanosecond pulses. Because spark gaps ...

Whenever an electrical circuit carrying considerable energy is opened in oil, gases are generated. These expand and rise, and tend to force the oil out of the containing vessel. They also form with air explosive mixtures, and either explode, or burn for a considerable length of time when ignited. It is important, therefore, that oil circuit breakers be provided with strong oil containing vessels in order that they may withstand the high initial stresses which are often present under certain conditions and also that suitable provision be made for retaining the oil.
Pulse voltage measurement techniques include crest voltmeters, voltage dividers, capacitive probes, electro‐optical transducers, and reflection attenuators. Spark gaps can be used for the measurement of crest values of voltage pulses from 1 kV to 2.5 MV. Good irradiation and short gap spacing are the key requirements of spark gaps for measurement of crest voltages of nanosecond pulses. Because spark gaps with small gap spacing can handle only small voltages of not more than tens of kilovolts, they have to be used in conjunction with calibrated voltage dividers for measurement of very high voltages. Pulsed currents can be monitored with resistive current shunts, Rogowski coils, B‐dot probes, current transformers, and magneto‐optic devices. The increase in the magnetic permeability improves the sensitivity and hence extends its usefulness for the measurement of low currents. Current transformers, used to measure alternating currents on high‐voltage power transmission lines, need a careful insulation design.
The simplest and most widely used high‐voltage impulse generator is the device Erwin Marx introduced in 1925 for testing high‐voltage components and equipment for the emerging power industry. This chapter discusses the principles of operation and overall performance of Marx generators. For instruction, the design formulas for simple Marx generators based on their equivalent circuits are given in considerable detail. A fully erected Marx generator is essentially a capacitive discharge. Thus, the load voltage depends not only on the characteristics of the Marx but also on the characteristics of the load. The chapter highlights some aspects in the discussion of modified Marx configurations. It reviews the importance of overvoltages to Marx operation, as well as advanced triggering techniques. The chapter also discusses various aspects of Marx generators such as electrical insulation, delay time and jitter, and the selection of components.
Closing switches are required to withstand high voltages and then rapidly enter a conducting state that will pass high currents with minimal losses. This chapter describes spark gap closing switches in considerable detail because of their ubiquitous use in pulsed power technology. It then describes other closing switches, including thyratrons, ignitrons, and pseudospark switches, as well as commercially available solid‐state switches. A spark gap is comprised of two conducting electrodes separated by an insulating medium, usually a gas, but liquids or vacuum are also used. The pseudospark switch exhibits remarkable switching properties, combining the advantages of thyratrons and spark gaps, specifically high_dI/dt_, reverse current, and charge transfer capabilities, along with long lifetime and low jitter. A solid dielectric switch consists of two main insulation sheets, a trigger insulation foil, and two metallic foils sandwiched between the main electrodes E1and E2by an external clamping force.
Summary form only given. The X-ray emission of highly overvolted spark gaps under electron runaway conditions is investigated. The pulse source, a RADAN 303 A, is connected to a test chamber through an oil-filled coaxial line, a coupling lens, and a biconical transmission line section, with a symmetrical arrangement attached on the opposite side of the chamber with a matching load. The test chamber allows pressure variation from 10<sup>-6</sup>-670 torr with argon or dry air used as a background gas. Voltage pulses with amplitudes of 40-150 kV, risetimes less than 200 ps, and FWHM less then 300 ps are applied across hemispherical electrodes with 1 mm spacing. A scintillator- photomultiplier combination with a temporal resolution of 2 ns is used as X-ray detector. Metallic absorber foils of different thicknesses are used to obtain a rough energy spectrum of the x-rays and electrons in the range of about 10 to 150 keV. Results show a high electron-energy component (>60 keV) existing up to atmospheric pressure, and an intense soft component (5 to 20 keV) at pressures around 100 torr. The observations are compatible with gaseous ionization and runaway conditions for extremely high E/p.
Many precautions are taken to avoid damaging electrostatic discharge (ESD) through disk drive magnetic recording heads featuring readback via a magnetoresistive (MR) sensor. By optimizing protective spark-gaps (PSG) in the recording head, the extent of ESD damage can be reduced. Human Body Model (HBM), Machine Model (MM) and Charged Device Model (CDM) transients are applied to simulated soft-adjacent-layer (SAL)-biased MR heads with and without protective spark-gaps. Design principles for ESD-damage-suppressing spark-gaps in MR heads are developed and several implementations compared.
Develop safety levels for human exposure to electromagnetic fields from 0 to 3kHz. This standard will be based on the results of an evaluation of the relevant scientific literature and proven effects which are well established and for which thresholds of reaction are understood. Field limits will be derived from threshold current densities or internal electric fields.
