Harmonic filter range ensures stable power quality

2014 has seen record levels of applications in which CP Automation's range of harmonic filters have been required, according to the company. The number and capacity of drives used in plant applications is increasing, and rising levels of harmonics are beginning to play havoc in industry, the most common problems including extreme stress on the electrical network, deterioration of the supply voltage quality and damage to equipment.

To ensure these issues are avoided and the power quality in industrial environments remains optimal, active harmonic filters could be used.

The powerful Comsys’ Active Dynamic Filter (ADF) has a reduced footprint and a high power density, suitable for ensuring power quality in office buildings, data handling centres, mines, chemical plants and in any other industrial application where drives and motors are present. The ADF series can handle any loss-creating behaviour in real time.

Highlights of this year's offering include a 4 wire 100A unit, UL Certified models and increased power ratings by 20% with cooling techniques. A liquid cooled version of the harmonic filter range is also available, allowing a significant increase in power.

The modular design of the Comsys active harmonic filters allows sections to be removed and replaced without the need for a plethora of connectors and cables. This makes the product quick and easy to install and maintain, without having to shut down the operation.

If one of the power modules develops a fault, the user can shut it down whilst continuing to run the active filter in reduction mode. This will keep plant harmonics low, while allowing time for the necessary maintenance.

The ADF series features significantly improved heat efficiency characteristics, compared to previous products, resulting in less wasted energy when continuously processing.

“We can’t stress enough how much of a positive impact the right harmonic filter can have on a company’s environmental performance, lowering energy consumption and improving productivity,” enthused John Mitchell, CP Automation’s business development manager. “The industry still suffers from a piercing lack of awareness when it comes to harmonics, so working with a professional partner that takes the time to understand and evaluate your application before recommending a solution is crucial.”
