Grounding System Maintenance Guide
Grounding systems are a crucially important component of any power supply system, because they directly impact public and employee safety, supply system reliability, power quality and life expectancy of power equipment. In spite of their crucial role in safe, reliable, and economic operation of power supply systems, grounding systems do not receive the same level of preventative maintenance as other infrastructure assets.
While utilities have generally adopted state-of-the-art risk-based maintenance practices for other important...
