Case study / Telecommunications facility
A conductor not fully seated in a breaker lug inside a rectifier circuit — identified through visual inspection after a small thermal rise prompted a closer look.
The situation
Inspection of DC power plant equipment and rectifier circuits at a telecommunications facility running on redundant backup systems.
The finding
A conductor not fully seated in a breaker lug inside a rectifier circuit — identified through visual inspection after a small thermal rise prompted a closer look.
The outcome
Repaired on-site during the inspection visit. The redundant system had been masking the thermal signature, demonstrating why opened visual inspection — not just thermal imaging — is part of the service.
