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 ...

On The Potential of Seasonal In-Ground Cooling Devices

Soil Mechanics and Foundation Engineering, 2005
It is demonstrated that when certain requirements are observed, seasonal cooling devices used for construction and repair, despite their complete or partial charging, which is governed by the procedures employed for work production, may be highly cost-effective components of cooling systems in the beds of structures.
