In Rocky Area the soil resistivity comes out to be very
high.The overall grounging structure is based on following
criteria
1.Area Of the Switchyard
2.Surface Layer Resistivity
3.Soil Structure
4.Safety PArameters
5.Fault Current Distribution
There Are Certain Techniques in case of HIgh Soil
Resistivity as
1.Deep Groung well Earthing
2.If area is limited of the Switchyard,use Remote grid
along with main grid buried in low resistivity material
3. Soil Treatment
4. Use Grounging rods to take effect of deeoer low
resistivity layers

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
