What is the definition of high-voltage and extra-high voltage according to NETA?

The definition of high-voltage and extra-high voltage according to NETA classifies voltages above certain thresholds to ensure safety and proper handling during maintenance and operations. High voltage is typically defined as greater than 100 kV (kilovolts) but less than 1,000 kV. This classification is critical for electrical professionals as it guides the design, installation, and maintenance practices required for safe operation of electrical systems at these voltage levels. It is essential for understanding the complexities and hazards associated with high-voltage systems, which differ significantly from low-voltage systems.

The other choices do not align with NETA's definitions for high and extra-high voltage. Therefore, the answer correctly captures the range established by NETA, reinforcing the importance of adhering to electrical safety standards in high voltage applications.
