Verified 2026-11-02 Confidence: High

Visual and Mechanical Inspection is specified for medium-voltage and high-voltage surge arresters in maintenance testing at clause 7.19.2.A of ANSI/NETA MTS-2023. The clause covers the physical and mechanical condition, anchorage, alignment and grounding, cleaning, bolted connections, the ground lead of each device individually attached to a ground bus or ground electrode, and the mounting and electrical connection of a stroke counter where one is fitted, with as-found and as-left tests around the cleaning.

Value: medium-voltage and high-voltage surge arresters
