| Seeking
a cause for power fluctuations, this Federal Pacific panel checked out fine with
sophisticated electrical meters. Tests were conducted by a master electrical engineer. |
An internal problem on the right leg of the panel heated to 53 0C
at 30% rated load levels. This panel was replaced to restore proper service and avoid
catastrophic failure. |

| This
300 HP Pump Starter passed a visual check and was found to be free of harmonics and within
load specifications. See its infrared image at the right |
Phase C contactor is the apparent cause of serious heating. This phase is
>31 0C hotter than the equally loaded reference at 22 0C. This
repair saved an $ 18,000 motor from damage and loss of snow making capacity. |

| We
were examining this rural treatment plant for insulation saturation. The insulation was in
good condition; but look at the infrared image on the right |
We found this potentially dangerous heating wire within the wall. If left
uncorrected, this overloaded wire inside the wall could cause a fire. |
