Routine Maintenance

Inspecting routine switchboard maintenance involves all the switchgear installations at frequent intervals (12 month intervals are recommended).  As part of our switchboard maintenance program, we perform a visual inspection, front and rear, to see that there is no evidence of loose parts, warping, or undue vibration.  If we do identify potential issues, we notify the client and our specially trained licensed electricians take steps to remedy any deficiencies of this nature that may appear.  Some items we look out for in switchboard maintenance is the moisture build up inside the boards.  We ensure that the assemblies and equipment are dry.  Keep the assembly dry.  Cover to prevent moisture from dripping on the equipment and ensure vents are not blocked. We offer this Routine Maintenance Service in the Western Australian Region. We service the Perth Metropolitan Area, North West Australia and also the South West Australia.

On-going maintenance checklist:

  • Perform an overall visual inspection. Check all indicators, meters, and instruments for proper operation.

  • Make sure all bolted panels are secure. Verify operation of heaters and thermostats, if used.

  • Check for undue noise or vibration that might loosen bolted connections.

  • Look for evidence of moisture in the switchgear.

  • Check the insulations are embrittled or discoloured insulation may indicate an overheated connection and need to be fixed.

  • Inspect all cables for tight connections.

  • Inspect control wiring for signs of wear and damage. Replace wires wherever doubtful.

  • Withdraw all drawout components and clean as per the circuit breaker manufacturers recommendations.

  • Clean air filters of vents.

  • Follow the recommendations of any individual device instructions furnished for maintenance of the device.

  • Indicating devices such as mechanical ‘ON’ and ‘OFF’ indicators, semaphores, etc. should be inspected to ensure that they are in good order and operating correctly.

  • Correct operation of any interlocks and padlocking devices should be verified and any adjustments required should be made.

  • Exercise circuit breakers by manually operating circuit breakers which will enable contacts to be kept clean and helps operating mechanisms operate freely.

  • Tighten all secondary control wire connections. Check for loose lug crimps and broken wire strands.

  • Reinsulate or replace any conductors showing damage to its primary insulation.

  • Thermographic survey after reconnections to ensure the thermal performance during operations.

  • Perform insulating testing.

  • Do functional testing of all circuits including emergency stop, shunt trip mechanisms, auto changeover, etc.

  • Upgrade any equipment that is obsolete in technology. Factors to consider include the operating environment, availability of spare parts, reliability, and the cost of ongoing maintenance.
