Research on Hanging Grounding Wire Device with Integrated Electroscope and Grounding

2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019
Hanging the grounding wire during the catenary daily power outage operation is the significant link to ensure safe work. While maintaining, the electroscope must be firstly used for electricity inspection before grounding wires. Since the operation is carried out step by step, it is easy to mistake tools and there might be inconsistency between the ...

Mathematical model of remote monitoring for grounding devices on overhead power line poles by measuring grounding device resistance

Energy Safety and Energy Economy, 2021
We report that we have built a mathematical model of a remote monitoring module for the purpose of control grounding devices located on overhead power line poles. The invention is based on measuring grounding device resistance. Resistance measurements conducted by the said monitoring module go directly to a power company’s control room.

4G/Multiband handheld device ground antennas

2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013
Promising internal handheld device ground antennas are presented. Using the ground antenna concept, the antenna element functions mainly as an exciter and can have a very small size to achieve 4G/multiband operation. In this paper, ground antenna structures for handheld devices including the use of a loop strip, a half-loop strip, a simple shorted ...

Compact Wireless Devices with Defected-Ground Structures

2006 International Conference on Wireless and Mobile Communications (ICWMC'06), 2006
In this paper are presented some investigations on micro- strip defected ground structures (DGS). It is shown that the presence of a slot in the ground plane can substantially enhance the electric coupling, or the electric part of a mixed coupling between resonators and its external feedings.

BASIC PRINCIPLES OF GROUND-CUSHION DEVICES

SAE Technical Paper Series, 1960
<div class="htmlview paragraph">A careful analysis is made of the basic principles which govern the operation of those ground-cushion devices currently known as ground-effect machines (GEM’s).</div> <div class="htmlview paragraph">Most GEM’s can be defined as machines which operate in close proximity to the earth’s surface without ...

Grounding electrodes and grounding devices. Regulatory requirements

Автоматика, связь, информатика
Одной из основных проблем при проектировании заземляющих устройств (ЗУ) в грунтах с высоким удельным сопротивлением является создание низкоомного заземляющего устройства. В последнее время широкое распространение получили так называемые активные (химические) заземляющие электроды, обеспечивающие искусственное снижение удельного сопротивления грунта в ...

Ground Penetrating Radar as a Sentinel Device

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2010, 2010
Geophysical methods provide a non-destructive non-intrusive method of subsurface investigation. Oftentimes, however, the target is difficult to “see” due to lack of contrast between the target and background. This lack of contrast can be rectified through the use of a sentinel device.

Ensuring Measurement Accuracy of Grounding Devices

2018 XIV International Scientific-Technical Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2018
The accuracy of measuring parameters of a grounding device depends, first of all, on the degree of protection of a grounding meter from the effects created by an electrical installation and a measuring circuit. The report considers such factors as asymmetry current of an electric network, direct currents in the earth, magnetic influence of a current ...
