Since an IPB forms an important integral part of a powergenerating station, with it are associated a number of metering and protective devices such as CTs. VTs and generator grounding system. Below we identifiy interconnections that may be required to connect these CTs and VTs while installing an IPB system.

Degradation of organic matter to generate ground gas is a complex biochemical and microbiological process. It is affected by variables such as volume of degradable material, moisture content, nature of material, pH of soil or waste etc. which in turn affect the level of risk associated with a source. There are various methods that allow a simple estimation... 

Numerical and physical models have been developed to examine the ground shaking that would be required to break and topple various types of speleothems. These models have been used to measure the natural frequencies and damping characteristics of speleothems and the peak ground accelerations necessary to break them. The natural frequencies of most speleothems are between 50 and 700 Hz, well above the range of seismically generated ground...
