Product By Features
LTECPower power transformers deliver more than power, that we deliver safe, efficient, and reliable customized engineering solutions for your power system through precise harmonic mitigation and grounding protection.
With advanced phase-shifting windings, our HMTs help you eliminate zero-sequence harmonics at the source, reducing neutral current overload, and protecting your sensitive equipment from distortion.
Providing a stable artificial neutral point for your ungrounded systems, our neutral grounding transformers help you with better fault current control and enhanced system safety.
Using high-performance cast resin or vacuum pressure impregnation (VPI) technology, our MV dry-type power transformers are fire-resistant, moisture-proof, and maintenance-free.
With copper or aluminum windings to match your project needs, our LV dry-type distribution transformers are optimized for your efficiency, heat resistance, and easy integration into NEMA 3R or IP23 protection enclosures.
Designed for 12, 18, and 24-pulse rectifier applications, our dry-type phase-shifting rectifier transformer minimizes your total harmonic distortion and electromagnetic interference for your most demanding drives.
Custom-Engineered Transformer Solutions for Your Complex EPC Projects
LTECPower engineers tailor transformer designs to your exact specifications, including non-standard impedances, special voltage configurations, or tight space constraints. Focusing on deep customization, our power solutions ensure you seamless integration into your complex power systems. From high-rise substations to critical grid-connected applications, we also deliver you fully compliant, ready-to-integrate solutions that meet IEC/IEEE standards and keep your project on schedule.
Advanced Harmonic Mitigation & Power Quality Engineering
If harmonics are threatening your power grid with overheating, neutral current overload, and system downtime, we can provide you with professional harmonic suppression transformers (HMTs) and phase-shifting rectifier transformers to help you solve power quality problems at the source. Utilizing advanced electromagnetic flux cancellation technology, our transformers significantly reduce your total harmonic distortion (THDi), protecting your sensitive electronic loads and improving your overall system efficiency which are widely trusted by data centers and heavy industrial facilities.
Robust Reliability for Extreme Industrial & Utility Environments
If you are looking for a long-term, reliable transformer solution for your utility and industrial infrastructure, we can deliver you dry-type transformers for your power grid safety and high efficiency. Featuring resin-cast and vacuum-impregnated designs, and high-grade insulation materials (F/H class), our dry type transformers are built to withstand extreme thermal stress, high humidity, and chemical corrosion to meet the needs of ungrounded systems with zigzag neutral-grounded transformers and fire-safe indoor substations.
FAQ
How Does a Harmonic Mitigating Transformer (HMT) Differ from a K-Rated Transformer (K-Rated Transformer)?
K-Rated transformer can withstand the heat caused by harmonics, but it doesn’t stop them. HMTs, on the other hand, use phase shifting to cancel harmonics, thus improving power quality and reducing neutral current.
Why Are Zig-zag Transformers Used in Wind Farms?
Most wind farms typically use ungrounded delta connections which do not have a natural neutral point. However, Zig-zag transformers provide an artificial neutral point to protect relays and isolate ground faults.
What Is the Benefit of Cast Resin (CRT) vs. VPI for MV Transformers?
It depends on your environment. Cast resin is the best choice for extremely humid or polluted environments due to its superior moisture resistance and higher mechanical strength. VPI is cost-effective but performs well in clean, dry indoor settings.
How Do Phase-shifting Transformers Improve VFD Performance?
By introducing a precise phase angle (like ±15°), phase-shifting transformers can cancel low-order harmonics, significantly reducing your total harmonic distortion (THDi) in multi-pulse drive systems.
Can LTECPower Match Custom Impedance Specs for EPC Projects?
Sure. We engineer transformers can meet your exact specific impedance, voltage, and spatial requirements, ensuring the seamless integration of your power system.
