The editors of Power Quality Assurance Magazine were alerted to the following errors:
The December 2000 article, “Power Quality Monitoring for High Reliability Systems,” contained two swapped figures. As a result, the captions did not correlate with the pictures, making it difficult for readers to understand the information. Shown at right are the correct figures and captions for Figs. 2 and 3, which appeared on page 35.
The cover story in the January 2001 issue, “Is Your Lightning Protection System What It Should Be?” also contained several errors.
The source for reference number 7 was not included. It is R. Golde, “Physics of Lightning,” 1977.
Lightning type (c), shown in the photo on page 10, should read “intracloud,” not “intrecloud.”
At the end of the first paragraph on page 12, the text in parentheses should read “25 ohms per NEC,” not “25W.”
