<h2 style="white-space:nowrap">Statement of Lessons Learned</h2>
<pre>A more robust control and monitoring system may have minimized the
damage from a transformer that failed and subsequently was destroyed by
fire. An examination of the event timeline indicated that early
detection may have identified problem and provided an opportunity to
repair or replace the unit.</pre>
<h2 style="white-space:nowrap">Discussion of Activities</h2>
<pre>On December 20, 2015, a 911 call was initiated for a fire in the 13.2
kV-1400V matching transformer for RF1 (one of the Advanced Photon Source
- APS - storage ring radiofrequency - RF - systems). The call was made
by a lineman when he saw smoke emanating from the transformer enclosure.
The fire department initiated extinguishing efforts once it was
confirmed that the transformer had been de-energized, and there was no
other electrical power being fed to it or into its enclosure. There were
no injuries and no run off into drains, damage was limited to the
transformer and its enclosure.</pre>
<h2 style="white-space:nowrap">Analysis</h2>
<pre>The transformer was an Olsun Electrics Corporation installed in 1996.
Its expected life cycle was 20-25 years.</pre>
<h2 style="white-space:nowrap">Recommended Actions</h2>
<pre>/Below are the consequences of the above event.They are provided for
information and discussion purposes only. /
The fire department used four or five extinguishers and then foam with
water to suppress the fire.
Power to the RF1 system remained locked out under administrative control
until a spare transformer and new enclosure could be installed.
The enclosure will be replaced with a newly fabricated enclosure.</pre>
<h2 style="white-space:nowrap">JLab Preventive Measures</h2>
<pre>Jefferson Lab Subject Matter Experts have read this lesson learned, but do not have enough information to determine Jefferson Lab's preventive measures. </pre>
