LIPA

LIPA Q: I have read a paper from the conference record of the 2008 IEEE International Symposium on Electrical Insulation (ISEI) by some folks at Powertech Labs from my home province of British Columbia. The paper was titled: “Condition Assessment of 15 kV Rejuvenated Underground XLPE Cables.” The cables in question are operated with AC,…

The Color of Capital

Q: My firm uses Cablecure 732 and SPR to treat cables after they fail. The ability to capitalize single section injection with Novinium technology means we can earn a regulated rate of return on the capital thus expended. I read your four-part blog, “The Color on Money” and was wondering if you could do a similar analysis to help us quantify the benefit of our approach.

Failure Causes III

Failure Causes III In my January 24th post, “Failure Causes I,” I provided a partial answer to an inquiry seeking to understand if rejuvenation technology was appropriate for the “many types of aging factors” from which his firm’s circuits might suffer. We learned that 39% or more of all circuit failures are component failures and…

Failure Causes I

Failure Causes I Q: I wonder if you have any information I could use to help address a concern I have heard in my company. That concern is that a 30 to 40 year old cable may have accumulated degradation due to many types of aging factors. Cable injection may not substantially address these factors…

Water Trees – Too Big to Fail?

Q: We had three cable samples sent out for testing from different areas. Each area has suffered multiple failures. We would like to have your opinion as to whether the injection process will be able to revive cables that have deterioration to this extent. Please send us any literature that you have, which can illustrate the extent of damaged cables and their successful rejuvenation.
