•Elevated voltages in neutrals and grounds is
reality. Proper design
practices can mitigate these voltages.
•Physically based modeling provides the basis to
study simultaneously
grounding, neutral voltages and safety.
•Disadvantage: More Complex Models.
•Observation: Electric power installations can be designed to be safe at low cost. Retrofitting is
relatively expensive. However, there is a substantial percentage of the industry that does not pay attention to this
issue at the design
phase.
