Substation Testing & Maintenance
Properly Grounded Substations
Adequate utility grounding improves power quality, but more importantly, it is essential for worker safety as well as public protection. Design is critical in maintaining a safe equipotential environment all around the substation.
Construction is important to accommodate fault currents without leaving the substation with dangerous potential gradients.
A tester must establish a sufficiently low resistance to remote earth so that operation remains within safe parameters. Similarly, safe step and touch potentials must be...
