Substation Grounding Role of Crushed Rock Voltage

Substation Grounding Role Of Crushed Rock Voltage

May 24, 2020 Application of crushed rock is a means of controlling step voltage and touch voltage. Step Voltage During a fault condition, a person walking on the surface of substation can experience a voltage potential between his two feet (typically assumed to be 3.3ft or 1m apart). This causes a current to flow from one feet-through his body- to other feet.

Compressive Strength Of Rocks Petrowiki

Jun 04, 2015 Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from


Classification Characterization Of Some

Intact rock strength . The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well -known point load strength index can be useful as the
