Overview of the role of power transformers

In a nutshell, power transformers (CTs) convert high currents into measurable values, enabling safe monitoring of high-voltage networks. They are indispensable in energy distribution systems, transformer substations and industrial installations.

In addition to measurement, these devices play an essential role in protecting electrical equipment and people by detecting fault currents. They integrate perfectly with metering systems, offering solutions to suit all configurations.

Power transformers in stock at One-Elec

The One-Elec selection includes a variety of models to meet every need:

  • PowerLogic power transformers stand out for their versatility and precision. The 250mm open flexible toroid model (reference METSECTR25500 associated with the A9MEM3555 energy meter) offers installation flexibility ideal for confined spaces or large conductors. For industrial applications, the DIN 400/5A power transformer, compatible with different busbar sizes, ensures reliable measurement in demanding environments.
  • The Vigirex range, which specialises in residual current protection, includes options such as the 200 mm diameter SA closed toroid, perfect for permanent protection, and the 120 mm TOA open toroid, which makes it easy to install on existing circuits without disconnection.
  • For maximum adaptability, our mixed power transformers, such as the TYPE A 250-5A and TYPE C 300-5A models, are suitable for a wide range of currents and can be easily integrated into various electrical system configurations.
