AI Thread Summary
Hanging buried jelly-filled cable overhead on an electric pole raises safety concerns, particularly regarding grounding and static charges. The installation is reportedly causing low voltage spikes that disrupt equipment during adverse weather conditions. The company responsible for the installation claims that the cable can be used overhead or underground, which is disputed by the telecommunications engineer seeking advice. Compliance with the National Electrical Code (NEC) is essential, as violations may require modifications or removal of the installation. Consulting local building inspectors may provide further guidance on the matter.

Hello,
My name is Jim and I found this forum through yahoo search engine. I am a Telecommunications engineer and I have a bit of a problem. I am 99% sure I am right on this but wanted to ask some experts please.

I have a customer who decided to go a cheapr route and have buried jelly filled cable ran overhead outside using an electrical pole (50k servicing a hospital and surrounding offices, homes etc etc)

The "buried jelly filled" hung cable is not grounded on the pole and we are suffering static charges/ low voltage spikes that is taking equipment out whenever bad weather or high winds occur.

The company who hung the cable stated the buried could be in ground or overhead, didn't matter? I am leaning to disagreeing with them as I put a stop point between the cable and the phone switch. When the customer "pulls the plug" on the cable they have suffered no interuption of service.

I have been looking for a document that explains the "why you don't hang buried-jelly filled cable overhead on a electric pole with that much power running through it.

Thank you for taking the time to read this and any help is so truly appreciated.
Jim

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
