Leading Industrial Harmonic Filter Manufacturer & Power Quality Expert
As a world-leading provider of filters and engineering expertise, LTECPower delivers high-performance active, passive, and sine wave filters to help you eliminate harmonic distortion, protect critical assets, and help optimize the energy efficiency for your infrastructure running cleaner, safer, and longer.
Global Manufacturing Excellence in Advanced Power Quality Engineering
As a Sino-German joint venture, LTECPower brings together German precision manufacturing and advanced automation to deliver harmonic filters trusted by the world’s most demanding industries. Every filter we delivered, from modular Active Harmonic Filter (AHF) to a robust Sine Wave Output Filter, all engineered to meet IEC 61000 and IEEE 519.
With state-of-the-art automated testing systems, premium high-temperature components, and world-class magnetic materials, our filters are specifically designed to address the complex electrical challenges facing modern smart grids, data centers, and heavy manufacturing facilities to deliver exceptional energy efficiency and an extended service life.
Beyond filter supply, we provide you comprehensive support for infrastructure projects, including technical documentation, Factory Acceptance Testing (FAT) services, and a reliable global supply chain. So your infrastructure stays protected from harmonic overheating, voltage transients, and utility penalties with longer life-cycle and lower costs.
Product By Features
LTECPower offers a complete suite of harmonic mitigation solutions, ranging from active correction with millisecond-level response to robust passive filtering and motor protection.
Solving Dynamic THDi Challenges with Active Filtering Expertise
LTECPower’s Active Harmonic Filters (AHFs) are built for the unpredictability of modern industrial networks. Different from static solutions, our filters respond intelligently to changing grid conditions in real time with modular, compact and energy-efficient system design. Featuring a modular design with high power density and low heat dissipation, our AHF systems integrate seamlessly into your existing switchgear, to keep your system from utility penalties and overheating.
Engineering Compliance: Meeting IEEE 519 & IEC 61000 Standards
More than comprehensive and fully compliant filtering systems, we also assist you in analyzing Total Harmonic Distortion (THD) characteristics to help you meet the strict harmonic limits set by power utilities worldwide. From detailed technical data sheets to data-backed simulations, our filtering systems deliver you maximum energy efficiency and system reliability.
Advanced Motor Protection for Critical Pump and Drive Systems
LTECPower’s Sine Wave Filters address the issue of premature motor failure—often triggered by the high-frequency switching operations inherent in Variable Frequency Drives (VFDs). This technology is widely deployed to protect mission-critical motors across the oil and gas, water treatment, and mining industries. Our filtering equipment prevents bearing currents and insulation breakdown, effectively smoothing the VFD output waveform to ensure the continuous, 24/7 stable operation of your critical drive systems.
FAQ
What Is the Main Difference Between an Active Harmonic Filter (AHF) and a Passive Harmonic Filter(PHF)?
An Active Harmonic Filter (AHF) actively “injects” reverse current to cancel harmonics in real time that are ideal for fluctuating loads. However, a passive harmonic filter uses LC circuits to “trap” specific harmonic frequencies that are perfect for stable, constant loads.
How Can I Get My THDi Below 5% With An Active Harmonic Filter?
LTECPower’s modular active harmonic filters can reliably deliver you THDi < 5% engineered in both 400V and 480V power systems
When Should I Choose a Sine Wave Filter Over a dV/dt Filter?
If your motor cable runs are long (>100 meters), then you shall go with a sine wave filter, for protecting older motors with weaker insulation and motor noise reduction. Otherwise, choose a a dV/dt filter.
Can LTECPower Supply Harmonic Filters With Custom IP54 Enclosures?
Sure. We offer a full range of enclosure protection ratings, ranging from IP20 for indoor cabinets to IP54/NEMA 3R for harsh industrial or outdoor environments.
Are Your Harmonic Filters a Drop-in Replace for ABB or Schneider Units?
Absolutely, and in many cases, we are better. LTECPower are committed to match or exceed the technical specs of major brands. In addition to providing the same or even better technical specifications, we keep you less waiting.
