The AS/NZS 3000, covers many of the Regulations about electrical installations state that “Licensed electricians must test all new electrical installations and any modifications to existing installations, including repairs, before putting them into service or use”. This is to verify that the installations comply with the requirements of the Australian Standard where applicable.

Testing Electrical Installations

When testing an electrical installation for compliance all parts of the installation, such as switchboards, sub-mains or outbuildings, must be inspected and tested for a full verification of the installation. Some of the inspections Nelvin Electrical will carry out on Switch boards, Distribution Boards & Motor Control Centers (MCC’s) are:

• A thorough visual Inspection will involve inspecting at the switch board panel condition, wiring, doors & locks and distribution board legend.
• We will also carry out an Infrared Thermography Inspection to detect any thermal anomalies.
• An earth loop impedance test will be carried out.
• Statutory RCD Testing.

Thermography is an extremely effective and very unique inspection method as its non-destructive and non-intrusive, meaning inspections can be conducted while plant and equipment is fully operational.Thermographic inspections are essential for preventative maintenance programs.

Infrared Thermography can be used in numerous fields, the most common being:

• Electrical (electrical panels, switchboards , power lines, equipment) ,
• Mechanical ( motors, gearboxes, bearings, conveyors)
• Buildings ( heat/cooling losses, insulation breakdown, leakage)
• Pipe work Tanks (leakages. Blockages, levels )

For any more information regarding Infrared Thermography Inspections please feel free to contact Nelvin Electrical

The power factor in an electrical system is reduced as more inductive load is applied into that system. The PFC unit automatically connects suitably sized switched capacitors into the power distribution circuit and the Power Factor is improved (closer to unity PF= 1)

The benefits of having a good power factor are

• Reduction of electricity bills
• Extra kVA available from the existing supply
• Reduction of voltage drop in long cables.
• Extended equipment life
• Reduced electrical burden on cables & equipment
• Reduction of power

Regular inspection and servicing of this equipment is essential as equipment failure can lead to fires within the units which could have devastating and costly results.

Nelvin Electrical will carry out a thorough inspection of your power factor units. We will ensure that the controller is set up correctly and that the capacitors are functioning correctly.

We are also able to carry out a full service and repairs to the PFC system.

The AS/NZS 3760 is the Australian Standard that provides guidelines and regulations for the Test and Tag with regards to electrical safety of appliances. It sets our recommendations to issues such as test and tag intervals, defines who can test and tag and general recommendations. The Test involves inspecting the appliance for any damage, followed by electrically testing it with a Portable Appliance Tester. A Tag is placed on the appliance to confirm that it has in fact been tested, along with showing who tested it, the test date and when the next test is due.  All employers have a duty of care to ensure the safety of its employees, meaning that if someone was hurt from an appliance that wasn’t tested and unsafe, they could be found liable.

Industry employers have a “Duty of Care”, to ensure their workplace is safe, and we suggest the testing of microwave ovens in the workplace annually as a minimum standard. This standard states that the microwave leakage power flux density of microwave radiation from any microwave oven shall not exceed 50W/m2 (5mW/cm2) or more from the external surface of the oven .The Microwave Oven is inspected for any physical damage to ensure safety and compliance.
