IEEE C62.23-1995

IEEE C62.23-1995 is an application guide for surge protection of electric generating plants, offering technical direction for protecting generation equipment and related power systems from overvoltage events. It addresses practical planning and coordination issues that can affect plant reliability, equipment life, and operating continuity. In the context of power, energy and industry applications, this standard helps engineers approach surge protection with more consistent design choices and clearer protection objectives for generation facilities.

IEEE C62.23-1995 overview

This standard focuses on surge protection methods for electric generating plants, where transient overvoltages may arise from switching, lightning, or other electrical disturbances. IEEE C62.23-1995 is intended as an application guide, so it is especially useful for understanding how protective devices and system practices may be applied in plant environments. It supports engineering decisions around coordination, placement, and protection strategy without replacing the need for site-specific analysis of the generating system.

Typical use cases

Typical use involves planning surge protection for generators, control circuits, auxiliary systems, and other plant equipment that can be affected by transient voltage stress. The guide may be consulted during plant design, retrofit work, or maintenance reviews when engineers need to assess protection for critical power and control infrastructure. It is also relevant when specifying protection practices for generating stations where continuity, equipment durability, and electrical system coordination are important operating concerns.

Why this standard matters

Surge-related damage in a generating plant can lead to downtime, costly repairs, and reduced system reliability. IEEE C62.23-1995 matters because it provides a structured technical basis for selecting and applying surge protection in a way that supports consistency across design and procurement decisions. For teams responsible for compliance, maintenance, or project engineering, the standard can help reduce risk by improving how protection measures are matched to plant conditions and equipment sensitivity.
