The negative impact of moisture on electrical equipment has been a serious concern since the beginning of the industry. Most senior plant personnel have had experiences with low insulation resistance (IR) and low polarization index (PI) values that have extended an outage. One example provided by subject-matter experts Neil Kilpatrick, GenMet LLC, and James Michalec,
