The Greek energy sector is undergoing a profound transformation. As Greece pivots towards becoming a regional energy hub in South-Eastern Europe, the demand for high-precision Current Transformers (CTs) has surged. From the massive photovoltaic (PV) parks in Thessaly to the wind farms in Evia and the strategic interconnection of the Aegean Islands, current transformers are the silent sentinels ensuring grid stability and accurate billing.
Industrial zones like those in Thessaloniki (Sindos) and Attica (Oinofyta) require robust measurement devices to manage high-load electrical consumption. Local factories and suppliers in Greece are increasingly seeking partners who can provide IEC-standardized equipment that can withstand the unique Mediterranean climate—characterized by high salinity near coastal ports and intense UV exposure in the interior highlands.
Greece aims for 80% renewable electricity by 2030. Our CTs are designed for the high-frequency harmonics of modern solar inverters and wind turbine controllers.
The Port of Piraeus and Thessaloniki are upgrading to "Cold Ironing" (Shore Power). We provide IP67 waterproof CTs essential for these marine environments.
Athens and major Greek cities are implementing smart metering. Our miniature PCB-mounted CTs support the next generation of IoT energy monitors.
Zhejiang Tanaka Electric Co., Ltd. is a high-tech enterprise specializing in the production, research and development, and sales of transformers and related products. The company's registered capital amounts to 110 million RMB. It has a strong technical team with 15 senior engineers, over 30 intermediate technicians, and 17 senior technicians. The powerful technical strength provides a solid guarantee for the research and production of products.
As of now, the company has obtained 18 patents, demonstrating its remarkable achievements in technological innovation. In addition, to better meet the diverse needs of customers, the company can also assist in purchasing other products on behalf of customers, striving to provide customers with more comprehensive and convenient services.
In recent years, the company has continuously increased investment in technical strength and modern equipment. Currently, we operate more than 120 sets of various equipment, including:
From raw material procurement and incoming inspection to finished product delivery, all implement strict monitoring processes. We incorporate the pursuit of "zero defects" into every detail, ensuring compliance with ISO9001, CE, and CCC standards.
The Greek regulatory environment, governed by HEDNO (DEDDIE) and ADMIE (IPTO), is shifting towards stricter accuracy requirements. For commercial and industrial billing, Class 0.2s or 0.5s accuracy CTs are now the standard to minimize energy losses and ensure fair billing in a liberalized electricity market.
Another significant trend is the rise of Split-Core Current Transformers for retrofit projects. Many older Greek factories are upgrading their energy management systems without wanting to disconnect existing cabling. Our split-core designs allow for "hot-swap" installation, which is a major advantage for continuous production lines in the food processing and chemical industries of Northern Greece.
Finally, sustainability is a key driver. Transformers today must not only be efficient but also environmentally friendly. Our dry-type transformers and high-precision sensors are designed for longevity, reducing electronic waste and supporting the circular economy goals of the European Union's Green Deal, of which Greece is a proactive participant.

*Note: For our Greek clients, we provide full technical documentation and support for ADMIE/DEDDIE grid compliance. Our products are tested to withstand high ambient temperatures and corrosive coastal environments common across the Greek Peninsula and Islands.
When selecting a supplier for the Greek market, one must consider the magnetic saturation characteristics of CTs. In solar-heavy grids like those in the Peloponnese, DC components can sometimes saturate standard CTs, leading to inaccurate readings. Tanaka Electric’s specialized R&D team has developed core materials with high permeability and specific air-gap designs to mitigate these effects.
Furthermore, our Split Core CT Silicon Steel Core Power Harvesting Devices (as seen in our product list: view here) are revolutionizing wireless sensor nodes in remote Greek mountainous regions where external power supply is unavailable. These devices harvest energy directly from the primary conductor to power IoT monitoring modules.
With hundreds of key power projects undertaken globally, our professionalism and ingenuity are unmatched. Whether it is a 363kV GIS Combination Current Transformer for high-voltage transmission or a miniature PCB Current Transformer for a smart home device, every unit undergoes rigorous testing. This commitment to quality has made us a preferred partner for engineering firms from Athens to Thessaloniki looking for reliable Current Transformer factories and suppliers.
