Fluke Process Calibration – Loop Calibration and Maintenance

Calibration is generally done for instruments that are used for obtaining accurate results. The outcome of a measurement is referenced with some standard values and checked for precision. Many manufacturers offer to pre-calibrate instruments prior to sale. The calibration documents are given with the device for the safety of the customer and for service purposes. Calibration enables both the users and businesses to be assured in the results that they record and control. Calibration is starting to diminish within domestic confinements and has taken over the field of manufacturing. As a result, devices in the market have become highly reliable, since the possibility … Continue reading

Our customers at Powerpoint Engineering regularly pose questions relating to Energy Metering. In this article, I have put together the following information that I hope will give you a better understanding of Energy Metering and the process of monitoring and tracking energy consumption.


Power Quality Monitoring – Reducing Costs with a Fluke 434

See how you can use the Fluke 434 Power Quality Analyzer to assess power quality and curb undue operating expenses caused which may be caused by equipment damage/downtime, poor performance/data loss, increased power consumption or numerous other factors. The Fluke 434 can help to detect possible problems which may occur that erode power quality and ultimately find a resolution for them before they prove costly. Continue reading


What is the law on PAT Testing?

The requirement for PAT Testing is relatively new here in Ireland. Apart from the regulation many insurance companies and standards authorities are insisting on companies developing PAT Testing within their organisation. The risks to employees, employers and businesses are very real – not only from the risk of electrical shock but also the risk of fire caused by faulty appliances. So what exactly does the law say about PAT Testing?


Portable Appliance Test Courses – What’s involved?

Everyone is talking about Portable Appliance Test Courses– but what’s the big deal? Portable Appliance Testing, more commonly known as PAT Testing, is the process by which electrical appliances are checked for safety. Not everyone can conduct these safety tests- to be able to carry out PAT Testing yourself you need to be deemed competent. In order to be deemed competent, you will need to complete a PAT Test Course, also knows as PAT Training Course.


How to Control Use of a Group Lockout Box for Isolations

The importance of effective and total energy isolation cannot be over-emphasised at every possible instance, given the heavy damage accidental re-energisation of equipment under maintenance continues to cause. Be it due to the lack of awareness, the absence of clear-cut processes and guidelines, or poor implementation of Lockout Tagout processes, it has been observed that de-energisation is a key contender for close attention, especially when working with automated and integrated processing systems. Energy Isolation in Complex Systems It is but natural for complex and integrated systems comprising a series of heavy machinery to be powered by multiple energy sources – … Continue reading


The Differences between Arc Flash Clothing and Flame Resistant Clothing

In certain industries, it is vital for employees to wear personal protective equipment for their safety. This includes those working in industries such as oil and gas, Data Centres, the military, electronics, and Large Manufacturing facilities amongst others. Some types of jobs within these and other industries put workers at risk of heat and fire related injuries, which is why the use of PPE is so important. One type of protection that has been used for many years by those working in these industries is FR clothing, which stands for Fire Resistant clothing. This type of clothing is designed to … Continue reading


Electric Arc Protection – Protection through Layers

Electrical hazards at the workplace range from mild electric shocks and burns to more severe injuries and health complications that result from brief yet powerful arc flashes. Electric arc flashes and blasts are capable of causing severe burns. The extreme heat and acoustic waves can damage vision, hearing or even trigger concussion and memory loss. The impact of such blasts can prove fatal, especially when workers are thrown off elevated work platforms, scaffoldings or ladders. Employers can ensure safety of workers, who are prone to electric arc risks as a part of the their daily jobs, by opting for suitable … Continue reading

Thermal Imaging Cameras & Predictive Maintenance

Thermal Imaging is the fastest growing non-intrusive predictive maintenance technology on the market today. Thermal Imaging Cameras are now an essential tool for predictive maintenance inspections, and are increasingly being used in industrial environments. Thermal Imaging is the only technology that allows you to immediately ‘see’ what’s wrong.


Misconceptions Regarding the Arc Rating of Infrared Windows

Thermal imaging has been in use for several years now to identify and remedy problems in electrical systems and automated industrial facilities. Infrared cameras can detect potentially problematic components from their heat patterns, making it possible to prevent electrical hazards in time. However, accurate imaging happens only when the electrical components are in the camera’s direct line of sight, with no obstructions, away from other dielectric interferences, and emissivity in the environment has been standardised.


Safety Factors to Consider for Substation Accessibility

Substations are potentially high-risk environments with a unique set of threats often hidden from the untrained eye. One step in the wrong direction can bring people too close to live equipment, an accidental stretch of an arm flipping a control switch can bring the entire facility to a grinding halt, or a dropped wrench can trigger an explosion. There are simply so many ways in which things can go wrong. These not only cause damage to assets and infrastructure but also compromise the safety and lives of personnel, apart from interrupting power transmission or distribution. Monitoring and controlling access right … Continue reading

Who Can Carry Out PAT Testing?

OK, so we know that PAT Testing is an essential part of any company’s Health & Safety Policy. But who is allowed to do it? Who is qualified to carry out PAT Testing? The IEE Code of Practice states that those carrying out inspection and testing must be competent to undertake the inspection and where appropriate, testing of electrical equipment and appliances. These competent individuals should have due regard to their own safety and that of others.
