IEEE C62.55-2020

IEEE C62.55-2020 is a guide for surge protection of DC power feeds to remote radio heads, addressing a practical reliability issue in communications and power systems. It focuses on how direct-current supply paths to distributed radio equipment can be protected from transient overvoltage events that may disrupt operation or damage hardware. By providing a technical basis for surge protection design, IEEE C62.55-2020 helps support more consistent engineering decisions where remote radio head power feeds must remain dependable.

IEEE C62.55-2020 overview

This standard sits at the intersection of power, communications, and electrical protection engineering. IEEE C62.55-2020 is intended to guide the surge protection of DC feeds used with remote radio heads, where the power path is part of a broader radio access architecture. In that context, the document is useful for understanding how transient events can couple into DC circuits and how protective measures may be selected and coordinated. It is most relevant where system uptime, equipment resilience, and repeatable design practices matter.

Typical use cases

IEEE C62.55-2020 is typically used when designing or evaluating DC supply protection for remote radio head installations in communications networks. It may apply to power distribution links between centralized equipment and outdoor or elevated radio units, especially where long DC feeds are exposed to switching surges or lightning-related transients. The guide is also relevant during specification review, site engineering, and procurement of protective devices for network hardware in broadcast and telecom environments.

Why this standard matters

In practice, surge protection for DC power feeds can affect service continuity, equipment life, and maintenance costs. IEEE C62.55-2020 matters because it gives engineers and buyers a common reference for protection design and evaluation in remote radio head applications. That helps reduce guesswork in compliance checks, improves consistency across deployments, and supports more reliable testing and acceptance of power-feed protection measures. For systems where downtime is costly, that technical clarity can be important.
