Lucky stars



A laborer with the pipeline company was digging with an iron bar up behind Woodlands .

He struck an unmarked High Voltage line [15,000V]
.
He was lucky to be uninjured but we had a big power disruption.

While we were restoring power, we found that we had no key for the new photovoltaic enclosures at PE. Bob had to pick the lock on the enclosure.
I didn't take any pictures but we found the pool pump house was all quiet. There are no phase loss monitors in any of the new buildings, but the four of the control voltage circuit breakers tripped resulting in complete shutdown of big motors. Don't know if this was designed in by EE or just lucky.
Also one of the three PV cabinets had a faulted 125A CB that shut down that one enclosure.

Recommend District consult with EE if Phase Loss Monitors required before next Hi Voltage event/
