AI Thread Summary
The CESMM3 Ref in the Bill of Quantities for Transmission and Distribution refers to the Civil Engineering Standard Method of Measurement, 3rd edition. The specific reference X9000.1 likely denotes a clause within the CESMM3 that pertains to measurement guidelines. However, the exact meaning of X9000.1 is not clearly defined in the discussion, leading to confusion among users. Further clarification or a detailed examination of the CESMM3 document may be necessary to fully understand this reference. Understanding these references is crucial for accurate project measurement and reporting.

What is the meaning of the CESMM3 Ref in BOQ of Transmission & Distribution?


In the Bill of Quantities of Some project of Electrical Transmission and Distribution I came across the CESMM3 Ref when I searched in the net I know that it is the " Civil Engineering Standard Method of Measurement 3rd edition ".

But my confusion is what is the meaning of X9000.1 represent. I think it is a clause of the CESMM3's reference having some information about measurement but not exactly find what it means.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

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...

Thread 'Following up on the recent thread about Earth Resistance measurements'

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...

Thread 'Question about bonding ground and neutral'

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...
