Reliability Engineering for Power Systems
Reliable power systems are designed around failure modes, operating states, maintainability, and verified recovery – not assumptions.
The engineering point
Engineering decisions made early prevent expensive field problems later.
What you'll take away
Identify failure paths
Map single points of failure and credible scenarios from source through load.
Build maintainable redundancy
Choose architectures that can be safely serviced without creating new hidden dependencies.
Prove the recovery plan
Test transfer, isolation, restoration, alarms, and operating procedures before an incident.

Predictive Maintenance for Switchgear and Breakers
Predictive maintenance uses operating data and trends to schedule breaker and switchgear work when the equipment needs it, rather than on a fixed calendar. This article explains how it differs from time-based and condition-based programs, which failure modes it can realistically anticipate, and where human judgment stays in the loop.
