SUBJECT:
Staff Update
ACTION REQUESTED:
None
DISCUSSION:
• In April, the locators processed 423 locate tickets. These consisted of 341 normal tickets,
4 emergency tickets, 34 updated tickets, 18 cancellations, 23 meets, 1 non -excavation,
and 2 corrections. This resulted in a 57.2% increase in tickets from the previous month
and is a 4.7% increase from the prior April.
• Electrical technicians completed 191 service order tasks, updated the power bill,
addressed customer meter issues and any off-peak concerns.
• On April 27, staff ran generators #1, #2 & #3 with no issues. Yearly oil samples were
taken after the run. No changes or concerns were noted.
• Tony Hubbard attended Minnesota Municipal Utilities Association's Generation School
April 18-20 in Hutchinson/Glencoe, gaining knowledge that will help us with maintaining
our generators. He noted that we need to further develop and document our
maintenance program for the engines along with several other suggestions.
• The malfunctioning line regulator along Highway 10 east of town has been taken down
and sent back to the repair shop for service. Staff hopes for a fast turnaround on this
warranty repair so that we can have the regulator bank back online before loads start to
increase. Voltage regulators help support downstream voltage by maintaining a
constant output that is regulated to stay within a certain bandwidth.
• While checking capacitors on the system, one was found to be closed when it should not
have been, leading us to suspect a bad controller. We did some further investigating and
found it malfunctioned on February 14. We have been able to reset it and we will
continue to monitor it further.
