Warranty

Concordance of IEEE 400.2™ & Warranty

September 12, 2011

The definition of “Discouraged Diagnostic Testing” found in your warranty language does not seem to allow VLF testing in accordance with IEEE 400.2™.* In the unlikely event that a rejuvenated cable fails in service, we would want to repair the fault and test the cable with one of the approaches outlined in IEEE 400.2. Is there some reason we should not, or cannot, test using IEEE 400.2 protocols?

Neutral Ampacity & Re-closers

September 8, 2011

Q: In Exhibit E of your proposal you state that cable replacement should be utilized rather than cable injection if the “cable neutral has lower than required ampacity …” I was able to find on Novinium’s website the limits for neutral corrosion, but nothing on the neutral ampacity limits. What are the neutral ampacity limits? Keep in mind that on three phase cable installs we use one-third neutrals. In Exhibit F of your proposal you define “Abnormal Operational Excursion(s).” One of the identified excursions, item (3), is “repeated operations of re-closers.” We use re-closers on all of our circuits. Does this mean that the warranty is void?

Neutral Corrosion Progression

May 10, 2011

Q: Can you please explain the rate of neutral corrosion? Specifically, do neutrals corrode linearly or in some other fashion? Also, an engineer asked me about stray voltage. We were discussing how Novinium will provide a warranty for a cable segment if 50 percent of the neutrals are good. He said, “Okay, but because of the neutral corrosion, I am having stray voltage issues affecting livestock on dairy farms. This can kill livestock. Stray voltage is also showing up sometimes on communications circuits.” How should I respond?
