Improved Safety with Sectionalized Components
Normal interface sections (breakers/switches) are physically separated from the power electronics sections and control electronics sections so that maintenance on a section can be safely performed. In addition, the interface and power electronics sections are each protected by dead-front doors, permitting accessibility - such as breaker operation and IR scanning, while maximizing worker safety.
If maintenance is required on the electronics section, power is bypassed to allow for safe repairs to be made. All connections are isolated using fiber optics to minimize risk.
