NETA Safety Standards & Regulatory Compliance 4

Question 1

Under NETA standards, what is the purpose of performing a dielectric withstand (hi-pot) test on electrical equipment?

Accepted Answer

To verify insulation integrity by applying voltage above normal operating levels

Answer

A dielectric withstand (hi-pot) test applies voltage above normal operating levels to verify that insulation can withstand overvoltage conditions without breakdown.

Question 2

According to ANSI/IEEE C2 (National Electrical Safety Code), the minimum vertical clearance for a 69 kV overhead line crossing a public road is:

Accepted Answer

28 feet

Answer

NESC requires a minimum vertical clearance of 28 feet for 69 kV lines crossing roads open to public traffic.

Question 3

NETA's testing standards require that the calibration of test equipment be traceable to:

Accepted Answer

NIST (National Institute of Standards and Technology)

Answer

NETA requires that test equipment calibration be traceable to NIST (National Institute of Standards and Technology) to ensure measurement accuracy and consistency.

Question 4

When working in a confined space that contains electrical hazards, which standard takes precedence along with OSHA's permit-required confined space standard (29 CFR 1910.146)?

Accepted Answer

Both NFPA 70E electrical safety requirements and OSHA 1910.146 apply simultaneously

Answer

Both OSHA 1910.146 (permit-required confined spaces) and NFPA 70E electrical safety requirements apply simultaneously when electrical work is performed in confined spaces.

Question 5

NFPA 70E defines 'qualified person' in the context of electrical safety as someone who:

Accepted Answer

Has demonstrated skills and knowledge of electrical construction and operation, and has received safety training on hazards

Answer

NFPA 70E defines a qualified person as one who has demonstrated skills and knowledge related to electrical equipment and installations, and has received safety training on electrical hazards.
