1. Many BIDOYNG units installed ~ 250 Reclose operations after faults > 80% customer supplies restored successfully

2. They said it would never fit there...

3. but it did! Design of BIDOYNG means it fits in 90% of UK substations but there are always exceptions...

4. “Fitting to an open indoor board will be easy” words I may have uttered once These stalks are part of an indoor LV fuse board. Check out the U shaped obstruction around the feeder stalk!!!

5. Fuse panels, layout, enclosures at LV substations vary greatly. We created a solution for the obstructed stalks, at the same time solving a problem for installation of REZAP

6. Kelvatek Web Very successful for managing LV faults, notifications of fault events & reclose operations, and shows necessary BIDOYNG fuse replacements Also has a button for access to power quality data

7. And we should get a nice data plot like this:

8. Dense data, taken every minute Stockport produced over 22M data points in first month Kelvatek Web data plotting slowed, and slowed, then stopped

9. Voltage and current are sampled at 51.2kHz (1024 samples per cycle) Transients are recorded, along with pre-fault data, on all 3 phases 3 phase data is fed to SELF - Single Ended Location of Faults

10. Example SELF Algorithm result : Malwood Road Substation Fault was arcing P-P, P-P-N, 3P & 3P-N 5 transient events recorded over 3 days SELF Calculated a maximum distance of 99m Fault located at 90m Accuracy > 90 %

11. Short term outputs: - Continued development of fault location algorithm - Fault location available to all field staff - Ease of access for power quality data - Fast interactive data presentation
