Under a blanket order, Tom McDermott has conducted several transient studies for Northeast Utilities:

• Effect of 345-kV cable installation on distribution feeder arrester applications
• 345-kV cable parameter sensitivity study on temporary overvoltages
• Study of temporary overvoltages on the 115-kV system in southwest Connecticut
• Study of transient recovery voltages associated with 115-kV cable installation
• Temporary overvoltage study of the proposed New England East-West Solutions (NEEWS) project. Model development and benchmarking has been completed, and the study is expected to continue for several more months.

Each study has required the refinement and extension of automated methods to prepare ATP simulation models and to generate reports.  These automated methods are essential for quality control and efficiency. The NEEWS project, in particular, has one of the most extensive and detailed models ever used in a study of electromagnetic transients.
