The Next Best-Practice in Reliability

Exacter Case Studies

Unitil saw that outages caused by equipment failure presented the best opportunity to improve overall system reliability. They began a program targeting all of their 3 phase circuits in 2012 that is continuing through 2017. Reduction in SAIDI and CMI far exceeded Exacter's estimate of 10%. Power Outages have decreased. Outages occurring at any of the problem locations could have resulted in over 1 million CMI each year. The results were so interesting that a full article was written and is featured in the October 2015 issue of T&D World Magazine.  Read More

National Grid Division, Long Island Power Authority (LIPA), conducted a two-year pilot program to examine the effectiveness and accuracy of the patented Exacter technology and overhead system assessment. At the completion of the pilot program, National Grid selected a number of components that were identified by Exacter as exhibiting failure signatures to be independently tested by EPRI for degradation and/or contamination. The results of the pilot program and independent EPRI study confirmed the effectiveness of the patented Exacter technology.  Read More

For more than 7 years, Wabash Valley Power has had a secret weapon helping them continuously improve their reliability. It’s a unique technology that enables them to find and repair invisible overhead line equipment problems before they cause a power outage. The secret weapon is called EXACTER® Predictive Technology.  Read More

Jackson Center did their first Exacter reliability survey in the spring of 2015.  Exacter uncovered 22 insulators and two lightning arresters.  The two Exacter surveys prevented significant problems that could have impacted the community's largest industrial customers "We let our customers know that we patrol the lines with Exacter to assure reliable power.  It's literally the best tool in our reliability tool box."   Read More

Coserve Electric serves over 152,000 member/owners in North Texas.  Amidst major electrical storms, Exacter was called in to perform health assessments in several key parts of the service area.  “Exacter’s predictive data provided unique insight into the overall health of our system.  It told us where specific weak points are located, which enabled us to stay ahead of future power outages and make our grid more resilient to the weather challenges that are inherent to this part of Texas."  Read More

Exacter's strategic partner, Davey Tree, performed an integrated reliability assessment that inculded IR, visual and Exacter technology.   In the year since the problematic locations were identified and repairs were made Pedernales Electric Company has seen a CMI reduction of 22% on outages related to overhead equipment across the entire distribution system.  Read More

In June of 2016, Exacter performed a health assessment of 100 miles of Orrville’s three-phase lines. Twenty-one locations were discovered where conditions were present that could lead to an outage. “The results were very interesting. I was glad Exacter found no problems on the lines leading-to-and-around the industrial park, but I was surprised at some of the finds. There was arcing equipment on streets we drive by everyday, but were showing no visible signs of deterioration."  Read More
