Thermal Scanning & Certification in Australia

Thermal Scanning & Certification in Australia

Thermal scanning of electrical equipment is quickly becoming a common practice in the electrical industry with companies realizing the importance of their electrical systems. Thermal scanning has been proven to significantly increase the safety and reliability of electrical systems. Companies are also looking to comply with their building insurance requirements and relevant Australian Standards which has several cost related benefits as well as the peace of mind knowing your installation meets current statutory requirements.

How you can benefit from Power Factor Correction?

Power factor correction (PFC) is an often-overlooked component in large electrical installations. It measures how effectively your business uses power by assessing the ratio of real power (kW) to apparent power (kVA). Real power is the amount of power which is actually used by your onsite equipment (kW) whereas apparent power is the total amount of power (kVA) supplied to the site by the utility.

Oil Sampling & DGA Analysis of Power Transformers

Power transformers are one of the most important pieces of equipment when it comes to electrical distribution. They are responsible for the transformation of higher voltages from distribution to lower voltages as seen in everyday electrical equipment. The most common type of transformer is the oil filled transformer.

De-energised Maintenance

Now that thermography and energised testing has been completed, it is important to also schedule time to shutdown power and perform de-energised maintenance on your equipment. Thermography and energised testing alone will not pick up every potential fault that may arise in your electrical equipment.

Energised Maintenance

Energised electrical testing is a great addition to thermography in a preventative maintenance program. While thermography generally points out potential problems that may exist within an installation, it is the energised testing that verifies these assumptions. Once a potential problem is identified the most common practices to pinpoint the exact cause of the fault is to test the equipment for electrical anomalies.

Breaking Down Thermography

Thermal imaging has quickly become a common practice in electrical maintenance. When performed correctly and in conjunction with other electrical testing methods, an accurate analysis of the condition of electrical equipment can be made.

Neutral Earth Resistors

Have you ever wondered what the large resistors connected to the neutral on an medium voltage (MV) installation is? It can look out of place sometimes, however, it has a very specific function that prevents damage to supply generators and switchgear.

Verifying MV Cable Sheath Integrity

As a cable jointer, most of the time I am called in to jobs at specific times during construction to complete high voltage cable terminations. I usually only see the end stages of most projects, and the cables have already been installed by other contractors. As the cable jointer and electrician certifying the cable installation, it is important to verify the cable has been installed appropriately.

How to Locate Sheath Faults on MV Cables

Maintaining healthy sheath insulation is extremely important for the safe operation and lifespan of an MV cable. If there are faults in the outer sheath, you can expect an ingress of moisture, debris, and the premature degradation of the cables structure.

The Basics of LV Circuit Breaker Maintenance

Understanding the construction and operation of the circuit breaker is incredibly important, as they are used in nearly every installation from domestic buildings to high voltage electrical utility substations.
