Electrical systems begin to deteriorate once they are built and installed. Performance and life expectancy of electrical and mechanical systems decline with environmental conditions, overload conditions, excessive duty cycles and wear and tear. The principal reason for any system failure is failure to maintain.

Preventative Maintenance

Dependable designs require maintenance to keep them dependable. An average of six hours (often longer) of business interruption is caused by each electrical or mechanical failure in your production process - what's the cost of six hours of your production time?

Failure rate is three times higher for any supply or equipment that is not part of a strategic preventative program. The risk of an unscheduled failure can be reduced by 66% with an effective preventative maintenance program - We can do a site survey and develop this for you.

What's the benefits of Electrical and Mechanical prevetative maintenance?

It improves safety for the facility and its technicians, by providing assurance that any protective devices will function. Safely clears fault conditions (Short Circuits, Overloading, Ground Faults, etc.) as arc-flash calculations assume equipment is maintained. It provides higher level of reliability and dependability, reducing the risk of equipment and system failure.

It Minimises property loss claims and subsequently lowers Insurance premiums, also minimising production time loss, and therefore the service to its customers. It enables your equipment and systems to operate at peak efficiency, making energy savings of up to 3% compared to non-maintained equipment.

Assisting with diagnostic and troubleshooting by providing reports on the state of a piece of equipment at a particular date and time. It controls the level of equipment repair and helps minimise replacement expenses. Equipment maintenance can be budgeted for and easily tracked, so you can implement changes and orrect deficiencies in a controlled way.

On average its estimated that it takes three times  the cost to fix the same problem.

Thermal imaging - the best way to see the danger coming

Thermal Imaging is one of the most valuable diagnostic tools for predictive maintenance. By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur.

Potential problems can often be found due to excess heat being released by the component, even those which would normally produce some heat when performing at their optimum level.

If undetected these problems can lead to failure and can result in expensive production loss or downtime and, in the most extreme case, can lead to fire.

A regular programme of thermal imaging as part of routine maintenance can highlight potential problems long before any event. As a result any required repairs can be planned for in terms of both time and budget. In short, it is an invaluable resource for predictive maintenance and it has many different applications;

Electrical applications:

  • Loose connections
  • Overloading
  • Phase imbalances
  • Corrosion
  • High resistance in fuse and switchgear                                                                                                                             

Mechanical applications:

  • Motor overload
  • Worn bearings
  • Seal leakages
  • Insulation breakdown
  • Tank levels and insulation
  • Valves and Turbines
