Earthing system audit
DEW Energy provides complete earthing audit for substations and industrial units using world class testing instruments and computer software from SES Technologies, Canada. Detailed analysis of incoming power and grounding integrity identifies distinctive problem locations and provides recommendations to enhance overall system performance.
- Earth Pit Testing
- Soil Resistivity Testing
- Advanced Earting simulation with computer software for:
- Safety Compliance
- Ground potential rise (GPR)
- Touch voltage
- Step voltage
- Fault current discharged by the grid
Why we need an advanced Earthing Audit?
- Safety compliance as per IEEE ST-80, 2000
- Smaller-area substations & higher fault levels
- More prevalent use of sensitive electronic machines/equipment
- Impact of transferred earth potentials needs to be mitigated
