Kerr electro-optic technique has been used to measure the electric field distribution in high voltage stressed dielectric liquids, where the difference between refractive indices for light polarized parallel and perpendicular to the local electric field is a function of the electric field intensity. For transformer oil, the most widely-used insulating liquids in power apparatus and high voltage...

From 1992 to 2012, a total of 911 paediatric burns were admitted and treated at Kanchi Kamakoti Childs Trust Hospital Intensive Burn Care Unit, of these 28 children had suffered electrical injuries and burns. 7 teenagers suffered high voltage electrical burn injuries: 2 were involved in train accidents which caused fatal electrical injuries, and 5 had electrical burn injuries caused by similar ...

Introduction: Recent developments of radiotherapy techniques, require high accuracy detectors to determine the delivered dose in a small area. Chemical vapor deposition (CVD) or naturally growth diamond detectors which are commercially available are good candidates for this purpose. In these detectors two electrodes with high different electrical potential are deposited on both...

We observe field emission between nanogaps and voltage-driven gap extension of single-walled carbon nanotubes (SWNTs) on substrates during the electrical breakdown process. Experimental results show that the gap size is dependent on the applied voltage and humidity, which indicates high controllability of the gap size by appropriate adjustment of these parameters in accordance with the applicat...

This paper presents an electrical stimulator with four high-voltage-tolerant output channels for cochlear implant in a 0.18μm low-voltage CMOS process. As the maximum stimulation voltage can be as high as 7 V, this stimulator only needs one single supply voltage of 1.8 V. To implement this stimulator in a low-voltage CMOS process, the dynamic bias technique and stacked MOS configuration are use...

Electrical transport studies across nm-thick dielectric films can be complicated, and datasets compromised, by local electrical breakdown enhanced by nm-sized features. To avoid this problem we need to know the minimal voltage that causes the enhanced electrical breakdown, a task that usually requires numerous measurements and simulation of which is not trivial. Here we describe and use a model...

The terahertz pulse energy from photoconductive antenna is mainly derived from that stored in the static bias field. To obtain high intense THz radiation, the distribution of electrical field in semi-insulating GaAs photoconductive antennas was studied at square DC bias voltage. Due to the trap-enhanced space-charge, the electrical field is enhanced at anode and extent to cathode. So the highes...

BACKGROUND Electrical injuries currently remain a worldwide problem. In Turkey, burns are relatively small in number among injuries overall, but they continue to be a major public health problem. Electrical injuries may occur due to high- or low-voltage contact. Injuries due to low voltage usually occur at home. High-voltage injuries are usually work-related and result from a shorter contact, b...

Voltage stabilizers are additives capable of inhibiting electrical treeing; a degradation mechanism for insulation materials subjected to strong divergent electric fields. The intended use is in cross-linked polyethylene (XLPE) high voltage power cable insulation where minute defects in the manufacturing process can give rise to the conditions needed for the initiation of treeing, which in the ...

The aim of our study was to retrospectively evaluate the epidemiological characteristics of patients with high voltage electrical injury from 1999 to 2009. The Clinic of Burns and Reconstructive Surgery, Faculty Hospital Brno is located in a region of 2,505,000 inhabitants. In total 13,911 patients (including both children and adults, and outpatients as well as hospitalized patients) were treat...
