PRECISION AT EVERY AMP
Scaling Down current,
Scaling Up CoNFidence
Pro-Lite offers medium and high-voltage current transformers suitable for metering, protection, and power monitoring applications. Our CT range is backed by decades of R&D and manufacturing experience, incorporating technology developed in Germany. Indoor models use Huntsman Araldite® epoxy resin insulation, and outdoor units use UV-resistant cycloaliphatic epoxy for long-term environmental durability.
Every unit is type-tested and routine-tested through a TAF accredited laboratory, with a wide range of accuracy classes, insulation levels, and custom configurations to suit specific project requirements, with ODM/OEM options available to tailor to your needs.

What is a Current Transformer?
Current transformers, abbreviated as CT, are specialized transformers used in AC electrical circuits. Together with voltage transformers (VT), they are collectively known as "instrument transformers." Current transformers function by transforming higher current (I1) on their primary side into lower current (I2) on their secondary side, maintaining a specific ratio. Typically, the secondary current is transformed into 5A or 1A, as prescribed by current IEC and IEEE regulations. The transformed current can be easily and safely measured, serving the purpose of monitoring and measuring electricity consumption in circuits and systems. Current transformers can also play a crucial role in providing protection to the primary side electrical circuits.
Pro-Lite offers two different classifications of current transformers: medium-voltage (MV) and high-voltage (HV) current transformers, which cater to power lines with voltages exceeding 600V. Depending on their application, current transformers can be divided into indoor and outdoor variants, as well as those used for measurement or protection purposes.
