About This Item
C62.11-2020 is a technical standard for oxide surge arresters used in AC power circuits above 1 kV, presented here as a redline edition for comparison and review. It addresses how these protective devices are specified and evaluated so they can help limit overvoltage stress in power and industrial electrical systems. For engineers, purchasers, and compliance teams, this edition supports clearer design decisions, procurement checks, and consistency in arrester performance requirements.
About C62.11-2020
This standard focuses on oxide surge arresters, the components commonly used to protect AC power circuits from lightning and switching surges. The redline format is useful when tracking updates against a prior edition, especially where technical requirements, ratings, or test-related language may have changed. C62.11-2020 is relevant to document control and engineering review because it helps define expectations for arrester application, performance, and conformity in higher-voltage AC installations.
Where is C62.11-2020 used?
C62.11-2020 is typically used in the planning, specification, and verification of surge protection equipment for utility networks, substations, and other AC power installations above 1 kV. It may also be referenced in industrial power distribution systems where voltage transients can affect insulation and equipment reliability. The standard is useful during design review, supplier qualification, and maintenance planning when oxide surge arresters are selected for service in demanding electrical environments.
Importance in practice
In practice, this standard helps reduce uncertainty around arrester selection and technical compliance. By setting a common basis for requirements and evaluation, it supports safer system design, more consistent procurement, and better comparison between products. For organizations working with high-voltage AC circuits, C62.11-2020 can also assist with testing and documentation, helping limit the risk of mismatched ratings, inadequate protection, or inconsistent interpretation of performance criteria.
