About This Item
C62.11-1987 is a standard for oxide surge arresters used in AC power circuits, providing technical guidance for equipment intended to limit overvoltage stress in power systems. It is relevant to power, energy, and industry applications where protection, reliable insulation coordination, and consistent arrester performance matter. As a superseded document, C62.11-1987 may still be useful for legacy equipment review, historical reference, and comparison of older design requirements with later practices.
C62.11-1987 overview
This standard addresses oxide surge arresters for AC service, helping define the technical framework for selecting and evaluating devices that protect electrical systems from lightning and switching surges. C62.11-1987 is focused on arrester behavior, ratings, and performance expectations in power circuit applications. For engineers and procurement teams, it offers a structured reference for understanding how these protective devices were specified and assessed in the context of utility and industrial power equipment.
Typical use cases
C62.11-1987 is commonly consulted for AC power installations that use surge arresters to shield transformers, switchgear, cables, and other connected equipment from transient overvoltage events. It may also support maintenance, refurbishment, and compatibility checks for older power network assets where oxide arrester specifications need to be verified against a historical standard. In utility and industrial environments, it helps align equipment choices with expected protection levels and system operating conditions.
Why this standard matters
For surge protection in power systems, clear requirements help reduce risk and improve consistency across design, testing, and procurement decisions. C62.11-1987 matters because oxide surge arresters play a critical role in limiting insulation stress and supporting system reliability during voltage disturbances. Using a defined standard can also help teams compare product capabilities, document compliance for legacy installations, and make more confident decisions when evaluating replacement or equivalent devices.
