Electric Power Quality: The Smoke of Modern Industry

Electric power has become an indispensable part of today's modern industrial world. Today, electrical energy has moved beyond being a secondary energy source and has taken on the role of the primary energy source. In other words, without electrical energy, a factory cannot operate. However, the mere presence of electrical energy is not sufficient for its use; it must also provide a certain quality (standard) to ensure its continuity.

So what is Power Quality?

It is defined as the ability of the electrical grid system to maintain the standard that ensures electrical devices operate healthily and efficiently within the tolerance range. More clearly, it is the condition in which the electricity supplied by the grid remains at nominal values in terms of voltage, frequency, and waveform. This standard is regulated internationally by IEEE 519 and IEC 61000 references and in Turkey by EPDK under the “Electricity Market Grid Regulation.”

What Are Common Energy Quality Problems?

Common energy quality problems encountered in electrical networks are classified as voltage dips and swells, harmonics, frequency variation, voltage unbalance, and transients. Additionally, from an operational perspective, reactive power is considered a quality problem that negatively impacts the system.

Why is Power Quality So Important?

The quality of electricity is crucial for the safety of the business and the continuity of production. Poor-quality energy poses fire risks along with insulation problems in the facility. It also causes a 30-40% reduction in the lifespan of equipment in the factory due to overheating, vibration, and malfunctioning, leading to high maintenance/repair costs. Furthermore, businesses encounter energy losses of up to 15%, particularly due to parameters caused by harmonics and reactive power. Companies that solve these energy quality-related problems with a professional engineering approach will establish efficient and profitable facilities in the medium/long term, along with sustainable production.

Energy quality management is becoming increasingly complex with the growing variety of power electronics-based loads and renewable energy sources. Traditional power quality solutions may be insufficient to solve problems under this complexity. Real-time compensation systems based on power electronics, which are currently developing, especially in terms of harmonic and reactive power compensation, will be one of the cornerstones of future energy quality management.

Finally, power quality is not a luxury, but a necessity for the sustainability of a modern business. Do not allow this invisible threat to harm your business. Power quality investments may seem like a cost in the short term, but they will provide significant savings and increased efficiency in the medium and long term.
