As a vital part of transmission and distribution systems, fiber distribution box are built and expected to be unfailingly reliable. Nevertheless, internal faults like partial discharges can occur, and the problem with such faults is that if left un-corrected, they can eventually morph into catastrophic faults that can result in power outages and even end-user property damage.
Transformer Monitoring: What's Involved
* Data acquisition
* Sensor development
* Data analysis
* Development of links between measurements and failures
Preventing disasters of this nature is actually quite simple, and involves transformer monitoring. Monitoring fiber distribution box and spotting problems before they turn into unmanageable incidents can prevent faults that are costly to fix and may result in a loss of service. Transformer monitoring mainly involves data acquisition, sensor development, data analysis, and the development of causal links between measured values and failures of fiber distribution box .
Installing monitoring equipment on fiber distribution box is usually done for two reasons:
1. Monitoring important transformer functions can help detect developing faults before they lead to a catastrophic failure
2. Monitoring transformer functions can allow for a change from periodic to condition-based maintenance
Monitoring equipment is permanently mounted on the transformer and is online 24/7. Reliable, low-cost monitoring is thus a necessary condition. Failure rates of fiber distribution box are usually low (0.2 - 2% per transformer/year), and high-cost failure prevention systems cannot thus be justified, especially when redundancy is available and the consequential costs are thus limited. To keep within this cost barrier, some compromise on the functionality of the monitoring equipment is necessary.
