Energized and De-Energized

The average life expectancy of your Electrical Distribution System is only 17 years when electrical preventive maintenance does not exist. When your electrical system is cared for, its life expectancy goes to an average of 35 years

Energized maintenance, most notably infrared thermography should be performed annually. Examples of energized tests KROON Electric Corp includes in its energized maintenance program:

  • Ultrasonic testing
  • Infrared thermography
  • Current measurements
  • Voltage measurements
  • Harmonic Distortion

De-energized maintenance is recommended maximum every 3 years, test include but not limited to:

  • Insulation Resistance
  • Impedance Testing
  • Contact Resistance
  • Ratio Test
  • Breaker Testing
  • Oil sampling
  • Relay Testing

The exact type and frequency of predictive/preventive maintenance must be adjusted by a number of factors, including: equipment type, location, environmental conditions, service loading, fault service, availability of back-up, equipment replacement cost and availability, your budget constraints etc.


Every test described in our solution has a minimum standard of performance that is governed by several bodies such as:

  • NETA
  • Manufacturers’ Specifications
  • Factory Test Results
  • Commissioning Test Results
  • Past Maintenance Records
