Power Quality products act as electrical filters by removing or reducing the level of harmful harmonics and re-shaping the sinewave for the longevity of operation of electrical systems. Variable Speed Drives are prolific creators of harmonics in electrical systems and as a result, most of the harmonic mitigation effort focuses on the input side and output side of a VSD. For the mitigation of harmonics on the input side (line side) of a VSD we recommend Line Reactors, Passive Harmonic Filters and Active Harmonic Filters. For the mitigation of harmonics on the output side (load side) of a VSD we recommend Load Reactors, dV/dT Filters and Sinewave Filters.
RFI (Radio Frequency Interference) is a high frequency disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, degrade or limit the effective performance of the circuit. RFI can wreak havoc with your electronics, computers, instrumentation and telephones, making your workplace difficult to work in. Since most machines have control electronic circuits, they may become difficult to control or unreliable.
RFI filters reduce the level of conducted RFI.
A fuse is a type of over-current protective device that is designed to be a sacrificial element in an electrical power system. Fuses are designed to open circuits when excessive currents are present due to over-currents, and are designed to prevent further damage to the system that might result if the fuse were not present. Fuses are sacrificial in that they are generally good for one time use and are destroyed in the process of operating. Short circuits, overloads or device failures are often the reason for excessive current.
The purpose of fuses is to protect components and equipment from costly damage caused by over-currents and to isolate sub-systems from the main system once a fault has occurred. All fuses are designed to open a circuit to protect other valuable components from over-currents. However, they are not all designed to do it in the same way! There are many different types of fuse performance options and selecting the correct performance for your application is vital. For this purpose, the IEC created 'Utilisation Categories' which define the performance characteristic of a fuse.
Around the world, DIN Rail Cartridge fuses and holders have replaced BS88 fuses & Red Spot holders. British Standard (BS88) Fuses & Red Spot Holde rs w ere designed in the 1950's, however, modern electrical environments are now much more complex and demanding and...
If you've ever had to replace a fuse, you may have realised that there's a few different fuse speeds. In simple terms, 'fuse speed' tends to refer to the time between the moment that an overcurrent begins and the moment the fuse arcs and opens the circuits. Most fuses can be considered to be fast acting, however there are also slow acting varieties, also...
The use of Passive Harmonic filters is growing rapidly and for good reason! In this economic environment, saving $$$$ is vital! These devices significantly reduce load applied harmonics in 3 phase power systems. But what does that mean for you?...
What is a fuse? A fuse is a protective device that is designed to protect an electrical power system from the harmful effects of over-currents (currents higher than the normal operating current). Fuses are sacrificial in that they are generally good for one time use and are destroyed in the process of operating. The use of fuses in a circuit...
Electromagnetic interference (or EMI, also called radio frequency interference or RFI) is a disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. The source may be...
As power utilities continue to be pushed to the limits of supply capability, rising energy costs and decreasing power quality will continue to be an issue for consumers. Users continually search for ways to not only reduce energy costs, but also ensure their processes will continue to operate, no matter the quality of the incoming power. To accomplish this, more and more...
Hi Julia, Yesterday I called you at 4.45pm and asked for "the impossible" - an overnight delivery for a customer's production breakdown. You said that you would help me and this morning, your package arrived. In my experience, I have never dealt with a company that can do what you guys did for me. You guys are amazing and very...
I have been in the electrical industry for 25 years and without a doubt the most competent and trustworthy supplier I have used over this period of time would be Fuseco. The staff are always cheerful, helpful and eager to please. Fuseco normally has in stock the vast majority of items I require and if not the lead times for goods needing to be ordered are regularly met. I...
Thanks for your assistance with getting these fuses to us. They arrived as said and we were able to get the plant up and running. Your service out of hours was much appreciated, I will be sure to recommend your company to others in the industry. ...
