Various software interfaces and diagrams illustrating electrical engineering concepts.

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.
