At Keentel Engineering, we know every reliable power system starts at ground level—literally. That’s why our licensed engineers deliver advanced grounding, earthing, EMI mitigation, and electromagnetic-field (EMF) analysis with the world-renowned CDEGS® software suite.
Since its first validation in 1974, CDEGS (Current Distribution, Electromagnetic Fields, Grounding & Soil-Structure Analysis) has been the global benchmark for grounding-grid design, lightning and surge studies, AC/DC interference mitigation, and environmental EMF compliance. Keentel Engineering couples that toolset with 30 + years of HV/MV project experience to give your substation, transmission line, renewable plant, pipeline, or industrial facility field-proven electrical safety.
Why CDEGS® matters
- Accurate soil & grid modelling – multilayer or exponential soil resistivity, complex conductor networks
- Fault-current distribution & GPR – touch/step voltage per IEEE 80, IEC 61936
- Lightning & switching-surge analysis – high-frequency transients, shielding optimisation
- EMI / EMF assessment – inductive, capacitive, conductive coupling on pipelines, rail & telecoms
- Environmental impact – corona, RI/AN, EMF reports for permitting and regulatory compliance
When millivolts—and project dollars—count, CDEGS delivers laboratory-validated results trusted by utilities, energy developers, and regulators worldwide.
