Staged Fault Testing: Demonstrating Results

This is part 2 in a series on staged fault testing. As more distributed renewable energy sources are connected to the grid, and heat...

Staged Fault Testing: A Proactive Approach to Grid Reliability

Staged fault testing is key to preventing protection system misoperations. This is not only important to prevent nuisance misoperations;...

Before Staged Fault Testing: Exploring Grid Conditions

Last week, we discussed the risk of wide area blackouts from renewable energy transfer to the grid. We concluded that staged fault...

Renewable Energy and Risk of Wide Area Blackouts

Last week, we talked about renewable energy transfer from the production source to the grid. We noted that the two best options for...

Staged Fault Testing: Equipment and Procedures

In our last post, we discussed the necessity of staged fault testing by reviewing three examples of protective relay misoperations....

Staged Fault Testing: A Necessary Precaution

After almost 10 years of study, the number of protective relay misoperations associated with high voltage facilities remains unacceptably...
