Dead-Front vs Live-Front Devices

Novinium News: March 2017

We have a long history of introducing new devices that assist us in improving the efficacy and efficiency of our rejuvenation services. The very first injection elbows were introduced about three decades ago. About one decade ago Novinium introduced Injection Adapters (IAs) that had several key advantages over injection elbows. The IAs were designed specifically to support Sustained Pressure Rejuvenation (SPR). SPR is safer and provides substantially higher reliability than the older Unsustained Pressure Rejuvenation (UPR) process and is even superior to our “improved” UPR process that we call iUPR. Sustaining pressure and keeping the silane injection fluid away from the injection component are the two main advantages of SPR over UPR and iUPR. Our advancements in injection application devices continues with the Modular Injection Component, or MIC.

Shields Scotty

Shields Scotty Inquiry What impacts do rejuvenation fluids have on the conductor and insulation shields? Response With Star Trek Into Darkness in the theaters it was appropriate to revisit the question of shields. Not the shields that deflect Klingon disrupter blasts, but the conductor and insulation shields used to smooth electrical stress in underground power…

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,…

Suitable for Treatment

Suitable for Treatment Q: We’ve taken some photographs of cable samples identified with off-line PD testing.  I was hoping to get your opinion of the cable and if injection would be able to address these issues. On two samples, we found the XLP insulation was a greenish color. We’ve never found cables discolored before and…

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…
