Power Quality

Enhancing electrical stability and efficiency through advanced harmonic filtering, reactive power compensation, and grid voltage control for industrial and utility applications

Power quality solutions are designed to maintain stable, clean, and efficient electrical power across different systems. They help reduce harmonics, correct reactive power, and minimize voltage fluctuations that can affect sensitive equipment. Devices like Active Harmonic Filter (AHF) and Static Var Generators (SVG) improve energy efficiency, protect components, and enhance the reliability of both industrial and utility networks.

How to determine whether to use a low-voltage or high-voltage power quality system?​

It mainly depends on the voltage level of the power grid where the equipment is connected. If the system operates on a 380V low-voltage network, a low-voltage SVG (Static Var Generator) or APF (Active Power Filter) should be used. For grids of 10kV and above, high-voltage models are the most suitable choice.

What are the benefits of using power quality equipment?

These devices help improve energy efficiency and extend equipment lifespan by compensating for power issues such as harmonics, voltage imbalance, and reactive power. They also reduce energy losses and prevent equipment malfunctions caused by poor power conditions.

Where are power quality systems commonly used?

They’re widely used in renewable energy facilities, data centers, industrial plants, power distribution systems, and other environments that require stable and reliable power supply.
