Safe Engineering Services & Technologies ltd. (SES) offers the most powerful grounding analysis software packages in the industry.
J Williamson Engineering is a licensed owner of Multi-GroundZ+ software which is part of the CDEGS family
Sigma SLP software is utilized to model the transmission line parameters and optimize the lightning performance of a transmission line.
SSH software is used for the optimization of high voltage substation direct lightning stroke protection system.
Field testing of grounding systems are be completed to verify the design model and the overall safety of the grounding system. Testing of a substation grounding system includes measurement of ground impedance, current split, Step/Touch voltages and resistance of buried connections.
