PREVENTATIVE MAINTENANCE2019-02-12T05:20:02+00:00


MBE Electrical provides a full preventative electrical and electrical engineering
maintenance service for industrial clients throughout Christchurch.

The benefits of preventative maintenance include:

  • Improved system reliability

  • Decreased cost of replacement

  • Decreased system downtime

  • Better spares inventory management

  • Reduced contractor callout costs.


MBE Electrical Services in Christchurch will provide you with a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures and saving you call out fees and costly errors.

What impact would it have on your company if a major component in your facility’s electrical system failed? What would happen to your plant’s production line or distribution centre? What would be the cost of down time, added to the repair or replacement costs for critical equipment?

The primary goal of preventative maintenance is to prevent the failure of equipment. It is designed to preserve and enhance equipment reliability by replacing worn components before they actually fail. This is achieved by recording equipment deterioration using thermal imaging, and condition monitoring, which allows parts to be replaced or repaired at the optimal time with a planned maintenance schedule.

The secondary goal of preventative maintenance is to ensure drawings and manuals are up to date and components of critical machinery are stocked, or supply chain investigated, allowing a fast recovery from breakdowns.


With thermal imaging cameras we can see underlying issues that cause heat. This untreated heat can cause major damage or in extreme cases fire, which can lead to major costs that could have been prevented.

Electrical heat can be caused by loose connections, poor contactor contact condition and excessive or imbalanced loading.

Mechanical wear or increased mechanical friction generates heat and can be detected with a thermal imaging camera. Mechanical heat is often generated by misaligned coupled equipment or pulleys, under or over greased bearings and failing bearings.

Condition monitoring is the inspection of electrical wearable components such as DC motor brushes and commutator components and large contactor contacts. It also includes site power analysis of harmonics and power factor correction units.

Both power factor and harmonics can cost companies thousands of dollars per year. Poor power factor correction will result in low power factor penalties and increased peak power charges.

The benefits of addressing poor power factor are increased system capacity and
reduced power consumption costs.
