Box Spring substation, Medicine Hat

A grounding study for a new substation in Medicine Hat

CIMA+ was retained by the City of Medicine Hat to produce a grounding (GND) grid analysis to ensure the safety of staff, citizens and equipment, as part of the MHS-10 Box Spring substation. The GND analysis was carried out using CDEGS software, as well as the RESAP (Soil Resistivity Analysis), Soil Model Manager software tool, MALZ (Frequency Domain Grounding/Earthing Analysis) and FCDIST (Fault Current Distribution Calculation).

These technologies allowed CIMA+ to model the GND grid of the substation in 3D to obtain more accurate results, which subsequently allowed for the necessary changes to be made in order to ensure the safety of people and equipment. The results confirmed that the design of the GND grid was safe.
