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.
After establishing a strong reputation over 16 years as Australia's premier supplier of fuse products, Fuseco has decided to expand its product offering into the area of Power Quality. What is Power Quality? Power Quality is the field of mitigating the effects of harmonics and RFI from electrical systems. Although a...
Be very careful when using semiconductor fuses in enclosed fuse holders! This issue is becoming more prevalent and unfortunately we are aware of a few recent cases where the mismatch of semiconductor fuses and fuse holders has resulted in a fire and expensive damage to a board. It's actually easy to prevent such events from happening, but first you need to know why they happen......
In recent times, we have received many enquiries from people who have installed a solar electrical system in their home or office and then mysteriously lost reception for their TV or AM radio. This can be an unfortunate consequence of installing an inverter...but there is a solution! Introducing Photovoltaic DC RFI Filters! If you have installed a...
Fuses have many unique performance characteristics, such as: Optimum Component Protection Fuses reduce short circuit (fault) currents that flow to a low value by "current limitation". There is no need for complex short circuit calculations and no concerns about costly future upgrades due to system expansion with increased fault currents. Their compact size offers low cost...
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 any object, artificial...
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 variable frequency...
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...
Elaine, most people are quick to criticize incompetent service but don't take the time to praise others who do very well. Today, your company was amazing! Apart from saving me a lot of money, I can't believe that you were able to solve our problem so quickly. You have created a loyal customer in me. Thank you. ...
Michael, you asked me if I was happy with your service. Let me tell you that Fuseco had quoted and delivered the products via airfreight from Germany before our other suppliers returned our call. Outstanding! ...
