Majengo Group Engineering offers effective on-site inspection and testing services to the street industry that cover all areas as being at risk to corrosion.

Test where  it matters.

The unique relative loss of section system was developed specially to locate and quantify corrosion of steel columns that cannot be identified by visual inspection .

            eg; Internal and external surfaces of the buried section of the root,and internal corrosion of the base and hot swaged joint .

The relative loss of section technique is a  dry coupled system that will provide a cost efficient assessment of the column. The result obtained estimates the percentage loss of section allowed to be classified (1 to 5) for either replacement or retesting at scheduled intervals. An electronic reporting procedure enables test results to be downloaded directly into the client’s inventory.

The Institute of Lighting Engineers (UK) has approved the RLS system for structural testing of steel lighting columns. For a complete cost  effective inspection and testing service that has been employed by many authorities and contractors in the uk and overseas . Then Relative loss of section has to be the obvious choice.

At 70% of rated life of the lamp on when 10% of the previous group relamping are logged to have failed appeared to be the  most economical range to conduct group relamping. Our calculations are based on these statistics.

• Fixture Cleaning

Periodic fixture cleaning ensures that all diffusers allow the maximum light output.

• Inspection

Group Relamping will allow us the opportunity to carry out detailed inspections. Through this we will be able to identify defects such as cracked lamp holders and loose wiring.

This practice also leads to poor lighting levels, as the lamp is only replaced when it fails. However, as all lamps age and near the end of their life, they can produce less and less light. This is referred to as planned lighting maintenance and includes three main aspects:

• Group Relamping.

• Fixture Cleaning .

• Inspection.

A planned lighting maintenance programme  will :

• Reduce labour costs

• Reduce the cost of lamps purchased in large quantities.

• Produce high levels over the life of the lighting system.

• Generate lighting upgrade opportunities such as reduced output energy saving lamps.

• Ensure proper inspection and upkeep of the lighting system.

Majengo Group Engineering can provide a planned lighting maintenance programme that will improve and ensure consistent recommended light levels and at the same time reduce costs through improved efficiencies of labour resources and through purchasing lamps in large quantities.

Around the world , best practice dictates that all earth leakage units should be tested periodically based on whether they are provided protection for wet or dry areas. We offer the service of both push button and function testing to ensure safety and minimize costs.

We believe that every installation should  be inspected on a regular basis, however the frequency will vary depending on the type of installation. An office may need to be inspected once every 10 years while a workshop may need it every 5 years.

The recent changes to the electrical Regulations relating to the construction sites state that:

All temporary electrical inspections must be inspected every week by a competent person

The post Temporary Electrical Installation Inspections appeared first on Majengo Group Engineering.

The following electrical equipments should be inspected on Regular basis,

• Portable electric tools
• Fixed electrical equipment . eg: Fridges, Water heaters
• Portable electrical equipment.  eg: Kettles, toasters.
• Extension leads

Majengo Group Engineering has the complete system needed to manage the inspection and maintenance of the above equipment. We make use of the seaward supernova portable appliance tester (PAT) linked to our electronic database.

The advantage of PAT is that all the following tests can be carried out using one test instrument,

• Earth Continuity test.
• Earth Bond test.
• Insulation Resistance test.
• Leakage test.
• Flash test.

Our database monitors all equipment and will email the client to inform them that their equipment will soon be re-inspected. Again not all equipment needs to be re-inspected every three months. The type of equipment will decide the Re-inspection date ,and this can vary from three to 24 months.
