Voltage Transformers / Potential Transformers (VT/PT) - Instrument Transformers | Maximize Electrical Efficiency with Top-Grade Current Transformers | CIC

Low-Voltage / Medium-Voltage Indoor & Outdoor Voltage Transformers (VT) manufacturer. Voltage transformers (VT), also known as potential transformers (PT), are a specialized type of transformers, collectively referred to as 'instrument transformers' alongside current transformers (CT). Voltage transformers usually consist of an iron core, a primary winding, and one or two secondary windings. In application, the primary winding is connected in parallel to an AC circuit with a voltage exceeding 200V. The VT converts the higher primary voltage (V1) to a standardized low secondary voltage (V2), typically 100V or 110V maximum (according to prevalent IEC or IEEE standards today). The secondary voltage is then utilized by instruments for purposes such as metering, monitoring, and protection through relays.Based on the primary voltage rating, VTs can be classified into low, medium and high voltage types. They can also be categorized as indoor or outdoor types based on application; and as metering or protective types based on function.CIC is the first manufacturer in Taiwan to specialize in cast resin voltage transformers, with over 45 years of experience in R&D and production of indoor VTs. CIC also utilizes advanced technology transferred from MWB Messwandler-Bau in Germany to manufacture outdoor medium-voltage metering VTs. The main insulation material used in CIC voltage transformers is Araldite® epoxy resin (cycloaliphatic epoxy for outdoor units), ensuring consistently high quality.CIC performs type tests and routine tests on all voltage transformers at its in-house Advanced Electricity Lab, accredited by TAF (an ILAC member). From design, type testing, to production and final testing, CIC self-controls the entire process to guarantee quality and on-time delivery.With a wide range of ratings in voltage ratio, burden, insulation class, materials, construction and dimensions, CIC voltage transformers meet various application requirements. VTs can also be customized to fit specific needs. CIC provides ODM/OEM services and manufactures products meeting different international standards. CIC voltage transformers have successfully reached markets in countries such as the United States, Canada, Russia, and Japan, with extensive use in power utilities, factories, major projects, electrical contractors for metering and distribution applications. CIC is a high-quality current transformers, voltage transformers, distribution transformers, epoxy insulators and power capacitors manufacturer from Taiwan. With over 45 years of expertise and technology collaboration with Germany's MWB, CIC is ISO certified and offers products recognized for reliability in various industrial applications. An ISO-certified company with more than 45 years of experience, CIC is a specialist in current transformers, potential transformers, distribution transformers, epoxy insulators, electronic meters, and other electrical and industrial products. CIC possesses its own testing laboratory with accreditation from TAF, a member of International Laboratory Accreditation Cooperation (ILAC). A transfer of technology from Messwandler-Bau (MWB) of Germany in 1990 further advanced the manufacturing expertise of CIC, whose current transformers and potential transformers come with a satisfaction guarantee.
