Preventative Maintenance for Electrical Systems 

  • Electrical Systems Begin To Deteriorate Once They Are Built / Installed

  • Performance and Life Expectancy of Electrical Systems Decline With

  • Environmental Conditions, Overload Conditions, and Excessive Duty Cycle

  • Principal Reason For Electrical System Failure Is Failure To Maintain

  • Dependable Designs Require Maintenance To Keep Them Dependable

  • Average of Six (6) Hours of Business Interruption Caused By Each Electrical Failure In Your Electrical System - (Laskey 2012)

  • Failure Rate Is Three (3x) Higher For Electrical Equipment That Is Not Part of An Electrical Preventative Program - (HSB 2010)

  • The Risk of An Unscheduled Electrical Failure Can Be Reduced By 66% With An Effective Preventative Maintenance Program - (HSB 2010) 


What is PM for Electrical Systems ?


The Process of Inspecting, Testing, Analysing, Servicing, and Mitigating Risks Associated with Electrical Systems and Equipment With The Purpose of Maintaining Safe Operations and Production By Reducing or Eliminating System Interruptions or Equipment Breakdown.


Benefits of Preventative Maintenance for Electrical Installations


  • Improves Safety For Facility and Technicians

  • Provides Assurance That Protective Devices Will Function

  • Safely Clears Fault Conditions (Short Circuits, Overloading, Ground Faults, etc.) – Arc-Flash Calculations Assume Equipment Is Maintained

  • Calculation Required For Operation / Inspection and Selection of Proper PPE  Provides Higher Level of Reliability / Dependability

  • Reduces Risk of Equipment / System Failure

  • Minimises Property Loss Claims / Lowers Insurance Premiums

  • Minimises Losses in Production / Service To Customer

  • Strengthens Operational Learning / Training of Electrical System

  • Observe Reactions of Electrical, Mechanical, and Control Systems  Enables Equipment / System To Operate At Peak Efficiency

  • 1% - 3% Energy Savings Over Non-Maintained Equipment

  • Assists With Diagnostic / Troubleshooting

  • Provides State of Equipment at a Particular Date / Time

  • Utilities & Engineering Services

  • Controls Equipment Repair / Replacement Expenses

  • Equipment Maintenance Can Be Budgeted / Tracked

  • Implement Changes / Correct Deficiencies Under Controlled Conditions

  • Reduces Emergency Repair / Replacement Expenditures

  • Approximately Three (3x) Cost To Fix The Same Problem
