Hybrid Transformers & Active Harmonic Filter

[INQ. NO. 2311M49] Transformers are the most important device in electrical installations, and can be used for 20 to 25 years. Therefore, safety and efficiency are the most important factors when choosing a product, so research and development are ongoing to meet these requirements.
Recent increases in the use of nonlinear loads such as LEDs, UPSs, inverters, and PCs have led to increased harmonics within the power system, resulting in significant power loss and diminished power quality.
Enertech Co., Ltd. is a technology-driven venture company founded in 2003, specializing in the field of harmonic waves and electrical quality. Leveraging over 20 years of accumulated expertise, the company provides a one-stop service from harmonic-wave diagnosis to solution delivery and maintenance, including after-sales service.

Hybrid transformers
Enertech’s flagship product, the hybrid transformer, is the only product of its kind in the industry, developed through collaborative research and development with the Korea Electric Power Corporation (KEPCO). This product is an all-in-one transformer that combines high-efficiency transformers and harmonics attenuation technology. It has been designated as a New Excellent Technology (NET) and Excellent Procurement Product, in recognition of its technological prowess. It has been installed and operated in over 700 major facilities, including public institutions and airports, validating its performance and efficiency. Unlike conventional transformers, the Hybrid Transformer can reduce harmonics without installing a separate harmonics filter, thereby increasing the stability and efficiency of the facility.

Moreover, Enertech recently launched the highest level of seismic-resistant transformers that can withstand seismic magnitude of up to 8.6 on the Richter scale. Its seismic performance is 0.88g or higher and suppression of seismic displacement is within 50mm. It has been recognized by the Procurement Service as an Innovative Procurement Product (industry-first), Excellent Procurement Product, and Priority Purchase Product for Outstanding Inventions.

Active harmonic filter
Enertech’s Active Harmonic Filter (APF) detects and offsets harmonics current generated by nonlinear loads in real time, which can save energy and prevent electrical accidents through expected effects such as harmonic reduction, improved imbalance, and reduced reactive power.
It utilizes DC-Link capacitor fault diagnosis algorithms, which enables maintenance cost-savings, and allows for lifespan prediction. It is effective for non-linear loads such as LED, landscape lighting, PC, inverter, server, electric vehicle charging, and especially effective when installed in data centers, automation facilities, expensive medical equipment, and commercial buildings.
