WYNTK Header ImageDe-Energized maintenance is an essential part of any asset and safety management program for your electrical systems. It increases safety and efficiency, can identify potential problems before they become major, and overall, is plain good business.

AnnualMaintenanceCostVsTimeConsider:

  • An electrical failure in your system causes, on average, 6 hours of business interruption. (Laskey 2012)
  • Equipment not under an electrical preventive maintenance program is 3 times more likely to fail. (HSB 2010)
  • Loose connections or parts, moisture, insulation problems and accumulation of dust, dirt and oil account for nearly 60% of electrical distribution system failures. (Based on Hartford Steam Boiler claims data)

PowerHawke believes that to truly asses the status of your critical power system it must be de-energized and tested on a regular basis.  Energized tests and inspections can only uncover so many anomalies on their own and must be paired with regular de-energized maintenance to promote the longevity and safety of your critical power system. Conducting visual and infrared assessments prior to de-energizing allows for repairs to be made during the shutdown, saving you downtime.

Powering off your system allows for a thorough cleaning and lubrication of your system’s mechanical parts.  We often find our client’s have dusty, dirty gear that requires housekeeping and exercising to function per manufacturer’s specifications.  We recommend de-energizing your system once per year to allow for this type of maintenance.

In addition to cleaning, switches, breakers, and transformers should have scheduled testing per NETA Standards, which can be viewed here:  NETA Frequency of Maintenance Tests  We’ve put together an easy ‘Frequency of Testing’ table for you.  Typically, de-energized tests should be conducted at least every three years.

PowerHawke can help coordinate shutdowns for your facility as we know there is much to consider when turning the power off.
