Service

Power system grounding or earthing system design

Design Procedure :

• Investigation of soil characteristics
• Determination of maximum ground current
• reliminary design of grounding system
• Cal. of resistance of grounding system
• Cal. of maximum grid potential rise
• Cal. of step voltages at periphery
• Cal. of internal step and touch voltages
• Investigation of transferred potentials and Special danger points
• Correction or refinement of preliminary design as indicated by 6,7and 8
• Construction of grounding system
• Field measurement of resistance of Grounding system as constructed
• Review of 5, 6, 7 and 8 based on actual Measurements
• Modification of grounding system or addition of screens and barriers, etc
