Lineman Quality Control Procedures 2

Question 1

When inspecting a compression splice on a conductor, which defect would cause immediate rejection?

Accepted Answer

Visible cracks or splits in the compression sleeve

Answer

Cracks or splits in a compression sleeve compromise the mechanical and electrical integrity of the splice and require immediate rejection.

Question 2

What is the primary purpose of a pull test performed on a newly installed dead-end assembly?

Accepted Answer

To confirm the mechanical holding strength of the connection

Answer

Pull tests verify that dead-end assemblies can withstand the specified mechanical loads without slipping or failing.

Question 3

Which standard primarily governs the inspection and testing of wood poles used in electrical distribution?

Accepted Answer

ANSI O5.1

Answer

ANSI O5.1 establishes specifications for wood poles used in overhead utility lines, including grading and strength requirements.

Question 4

A lineman notices a transformer oil sample has a dark, burned appearance during a visual QC check. This most likely indicates:

Accepted Answer

Presence of dissolved gases from internal arcing

Answer

Dark, burned transformer oil is a strong indicator of internal arcing or overheating, which produces dissolved gases and degrades the oil.

Question 5

What does NESC stand for in the context of quality and safety standards for electrical construction?

Accepted Answer

National Electrical Safety Code

Answer

NESC stands for National Electrical Safety Code, which sets minimum requirements for overhead and underground electrical construction.
