In today’s industrial and commercial environments, maintaining optimal power quality is paramount. Non-linear loads, such as variable frequency drives and rectifiers, introduce harmonics and reactive power issues that can compromise system efficiency and equipment lifespan.
Understanding the Basics
Active Harmonic Filters (AHFs): AHFs are designed to detect and compensate for harmonic currents in real-time, ensuring that the current waveform remains as close to sinusoidal as possible.
Static Var Generators (SVGs): SVGs provide dynamic reactive power compensation, stabilizing voltage levels and improving power factor.
Basic Sizing Steps
- Collect transformer capacity, load type, voltage level and operating profile.
- Measure harmonic current, reactive power demand and power factor at the point of common coupling.
- Select AHF capacity according to harmonic current and SVG capacity according to reactive compensation demand.
- Confirm installation space, cabinet type, cooling and communication requirements.
- Contact iKonMac for project review before final model selection.
