Avoid unwanted disruptions and losses
Optimize the quality of electricity
The right quality of voltage and current (Power Quality) is essential for businesses and organisations, including businesses in the metal sector. As a result of the increased use of technological innovations and inverters - such as frequency controllers – harmonic distortions will arise within the grid. This increasingly causes problems for the continuity, efficiency and security of the electrical installation. A bad Power Quality can have extensive and costly consequences such as equipment failures, production downtime and fire.
Loss of capacity and energy
Disruptions and failure of machines and equipment
Shortened lifetime of machines and equipment
Increased temperature within cables, transformers and distributors
OVERCHARGE – PRODUCTION DOWNTIME – FIRE
Improve quality by filtering pollution
An advanced method to reduce harmonics is the use of Harmonic Filters. Through its use the Power Quality will be optimized and the risk of production loss, equipment failure and loss of equipment is minimized. In addition there will be a reduction of energy losses and the available capacity will be optimally utilized. An Active Harmonic Filter is installed in parallel to the installation thus harmonic distortions that are created by multiple devices can be reduced with just one Active Harmonic Filter.
Case with Active Harmonic Filter in the metal sector
A metal processing plant had to deal with regular distortions in two of its production machines. However the cause of the problems could not be determined in the first instance, a comprehensive Power Quality scan showed contiminated electricity (harmonic pollution). After the scan HyTEPS advised to install an Active Harmonic Filter. After installation and commissioning of the filter the harmanoic distortion was immediately reduced to acceptable vallues (see chart), minimizing the risks of future Power Quality problems.
Optimal capacity use by reducing reactive power
Reactive power creates unnecessary costs and an inefficient use of the installation. Reactive power is often seen in companies in the iron and metal industry because of the presence of inductive linear loads (motors, transformers, reactors) and inductive non-linear loads (motor drives, welding equipment, rectifiers, UPSs) within this sector.
Increased costs on the network operator’s invoice is a first indication of reactive power within your installation. As standards will be set increasingly stringent in the future, higher costs will ocurr more often. Even if you are not faced with higher costs, there is a possiblity of reactive power in your intallation. A Power Quality Scan can make this visible. Any possible reactive power can be reduced to almost 0 by placing one or more capacitor banks.
