Minimizing Harmonic Interference in Cathodic Protection Systems
For critical infrastructures such as highways, bridges and pipelines, cathodic corrosion protection (CCP) is an important tool for protecting systems from corrosion, which can cause significant structural damage. If the degree of corrosion is not controlled, there is a risk that the systems will become unsafe and have to be shut down. Steve Hughes, Managing Director of power quality specialist REO UK, explains how harmonic currents affect the effectiveness of CP systems and how to protect against them. Corrosion is a natural, electrochemical process in which metals are gradually destroyed as part of two simultaneous chemical reactions. A common example of this is rust, in which iron is electrochemically converted into hydrated iron oxides by oxygen and water. Two reactions occur simultaneously: an anodic oxidation that destroys the iron and a cathodic reduction with electron transfer between the anodic and cathodic cell through an electrolyte. CP systems are used to protect metal structures from corrosion by making them the cathode of an electrochemical cell. This is achieved by applying an external electrical current to the structure, which drives electrons into the metal, so that the electrochemical potential of the metal is more negative than that of the environment. This prevents the formation of a protective layer of corrosion products on the metal surface. Typically, CP systems use rectifiers to convert AC to DC. The switching from AC to DC and back through the rectifiers generates harmonic current waveforms that are multiples of the mains frequency. These harmonics have several negative effects on the grid, including increased heating of the rectifiers and other equipment, increased voltage drop in the power lines, interference with other electrical equipment, and reduced efficiency of the CP system. Control of harmonic interference There are numerous ways to reduce harmonic problems in CP systems, such as oversizing the rectifiers, using parallel rectifiers, and using a power factor correction device. Oversizing the rectifiers can help reduce the amount of harmonics generated. This is because the larger the rectifiers, the less likely they are to introduce harmonics into the power grid. The use of parallel rectifiers can also help reduce harmonic emissions. This is because the current flowing through each rectifier is reduced, which reduces the likelihood of harmonics being generated. The use of a PFC device can help improve the power factor of the CP system. This is important because a high power factor can help reduce the amount of harmonics generated. While oversizing rectifiers and using parallel rectifiers are effective, they incur significant operating costs, so these solutions are not always practical. The most cost-effective method of reducing the negative effects of harmonic currents is generally the use of harmonic filters. These are devices that filter harmonic currents from the grid. In addition, there are a number of other measures that companies can take to mitigate harmonic problems in CP systems. These include ensuring proper grounding of the system, using high-quality rectifiers that allow efficient switching from AC to DC, regularly monitoring the CP system to identify any problems, and performing regular maintenance, especially if problems are detected during monitoring. By following these tips, you can help ensure that your CP system operates safely and efficiently and does not cause harmonic problems.

Demand for Modern Resistors from REO Rose Significantly in 2022
Not only since the new geopolitical situations in 2022 has the electrification of products or entire industries been in high demand. The electrification of mobility is progressing in all sectors of the economy, and REO components prove their resilience and reliability every day. Thanks to the high scalability of the power classes, mobility solutions can be electrified, from small autonomous robots to buses and container ships. The advantages of electrified drives are obvious. Compared to conventional drive types such as the internal combustion engine, electric drives have a very good degree of efficiency. At the same time, the e-drives have a significantly lower weight in relation to their power and cause no local emissions. However, in order for an electrified drive system to work safely and reliably, special components are required. For example, REO braking resistors protect the machine from overvoltage in the DC link. For your applications (e.g. wind power technology, railway technology, automotive technology) they guarantee a high level of operational safety and are overload-proof in the event of short-term loads. The charging resistor, on the other hand, is a current limiting resistor for charging and discharging capacitors and limits, for example, the inrush current flowing into the DC link capacitor. For this purpose, the device must be designed for a high single pulse energy and rated voltage. For particularly effective cooling in the most adverse conditions, REO offers a wide range of liquid-cooled components. Liquid-cooled resistors, such as the REOHM D 330 from REO, are significantly smaller than conventional air-cooled resistors and are available in power ratings up to 60 kW. The efficient cooling is achieved by means of cooling channels incorporated in the heat sink, which enable cooling below the ambient temperature and create a safety-relevant spatial separation of the current-carrying and liquid-carrying lines. Further advantages are a high power density and an efficient and low-noise operation. REO products are characterized by a long service life and low maintenance requirements. This not only has financial advantages, but also saves resources that are needed for new products or spare parts. With our products, you can therefore contribute to minimizing the global waste of resources. Become part of REO’s consistent path to greater sustainability. We have set the course for a sustainable future and stand behind our ambitious goals. Our claim is based on the holistic strategy of reducing emissions and consumption in all production and company areas. Share the news: Also interesting
