Energized and De-energized Preventive Maintenance

Insulation Resistance Service: Measure and record the resistance of insulation under specified conditions set forth by manufacturer or NFPA Standard 70B.  This service is designed to assure that your electrical system and components’ insulation values are at an acceptable level, reducing the risk of explosions, fires and catastrophic breakdowns.

Winding Resistance Service: Measure, record and compare the winding resistance of components.  This service will assure that components are operating to manufacturer’s specifications, extending useful life, and reducing the risk of catastrophic failure.

Contact Resistance Service: Measure and record the resistances present between contact surfaces.  This service addresses poor contact surfaces that would cause increased voltage drop, increased heat and reduced life expectancy, causing brown-outs, black-outs, explosions, fires and catastrophic failures.         

Ground Resistance Service: Measure and record the resistance of conductors, connections and devices.  This service will reduce the risk of power quality, harmonic and safety issues.

Circuit Breaker Service (Low Voltage): Measure, test, record and document findings regarding all applicable low voltage circuit breakers.  The proper Service and inspection of your circuit breakers will reduce the risk of business interruption, fire and catastrophic failure.

Motor Service: Measure, record and monitor all appropriate service and inspection to manufacturer’s recommendations and/or NFPA Standard 70B.  This service and inspection is performed to monitor and trend the motor and to reduce the risk of failure.

Transformer Service: Measure, record and monitor all appropriate service and inspection to manufacturer’s recommendations and/or NFPA Standard 70B.  This service and inspection is performed to reduce the risk of transformer failure, which could result in fire, and/or catastrophic failure.

Transformer Oil Analysis

Exercising: Exercise all active components (when applicable).

Check Tightness: Torque all connections and terminations to applicable specifications.

Lubrication: Lubricate, as appropriate, to assure proper mechanical function(s).

Cleaning: Clean interior and exterior of equipment, including vacuuming or blowing out as required. 

Analysis: Compare test results and trends in order to determine appropriate actions to minimize the likelihood of an unscheduled business interruption or safety hazard.
