Grounding for power systems is an often misunderstood, yet crucial aspect of protecting power equipment and utility personnel while also minimizing downtime. A properly engineered grounding system will not only allow surge arresters to operate, but will also limit ground potential rise (GPR) and touch...
In 2019, SAE was contracted by Cascades Casino in North Bay, Ontario, to design the grounding system for the main supply transformer. After conducting soil resistivity testing and developing a layered soil model, it was evident that this area would not require an extensive installation...
Cathodic protection (CP) anode beds are typically installed using carbonaceous backfill materials such as coal coke breeze, calcined petroleum coke breeze, or graphite particles. These carbonaceous backfills help reduce the contact resistance of the individual anodes in the anode bed by increasing the size of...
SAE’s newly formulated conductive backfill -- Conducrete®, is now available in a 25-lbs bag. Not only does the improved formulation dramatically enhance the performance and reliability of grounding and cathodic protection systems -- it also increases the longevity. Conducrete® offers many advantages: Theft resistant and requires...
Without proper grounding, personnel and the general public are at higher risk of shock or electrocution and electrical equipment is at risk of malfunction and irreparable damage from voltage and current surges. It is a fact that lightning and power system ground faults will find...
