The transformation of power grids towards smarter, more sustainable systems adapted to the needs of the 21st century presents new challenges for power distribution operators and users. IMEFY, with more than 50 years of experience in the sector, responds to these demands with the development of the Peritus OLTC Transformer (POT), a transformer with on-load tap changer that combines compact design, high precision and automatic regulation, as well as advanced digital management to integrate seamlessly into smart grids.
This transformer was officially presented during the Intersolar Europe 2025 trade fair, generating great interest among industry professionals.
Advantages and solutions of the Peritus OLTC Transformer
The POT stands out for its technical and operational characteristics, designed to facilitate voltage stability and quality in electricity distribution networks, while respecting the environment and contributing to energy sustainability.
1. Compact and sustainable design. Its design does not significantly increase dimensions and weight compared to a standard transformer. It is maintenance-free and suitable for the use of sustainable insulating liquids, such as vegetable esters, which reduce the carbon footprint. This makes it possible to take advantage of existing installations without the need for costly modifications, improving economic and environmental profitability.
2. Precise and automatic regulation. Thanks to a wide regulation range with very small steps, the POT maintains the voltage within narrow regulatory limits. Its automatic regulation, based on direct measurement of the secondary voltage and controlled by internal algorithms, adjusts the voltage in real time without the need for transformer disconnection or manual intervention. This capability makes it an ideal solution for critical points such as electric vehicle charging stations and renewable generation plants.
3. Integration in smart grids. The transformer is prepared for integration in SCADA systems and smart grids through standard communication protocols (IEC 101, IEC 104, DNP-3, IEC 61850, among others). IMEFY offers a proprietary application that allows remote monitoring and management of the POT, optimizing operation and facilitating maintenance.
4. Improved profitability in renewable generation. In photovoltaic and wind projects, the decoupling of the secondary voltage with the on-load tap changer avoids oversizing and maximizes the use of available reactive power, eliminating the need for external compensation facilities and thus increasing the efficiency and profitability of the installation.

Smart application for Peritus OLTC Transformer management
IMEFY offers an advanced application that enhances the efficiency and sustainability of the POT through:
- Real-time remote monitoring of electrical and thermal parameters.
- Remote control of the tap changer for adjustments without travel.
- Load and overload management, including predictive calculations of remaining useful life based on temperature and operating regime.
- Predictive and corrective maintenance, with coded alarms and suggestions for quick and effective intervention.
- Customization and multi-user, with integration to control centers or stand-alone operation.
This tool turns the POT into an intelligent device that facilitates remote management, increases reliability and reduces operating costs.
Environmental commitment and sustainability
IMEFY has developed a solid business model aligned with European sustainability directives (CSRD), promoting environmental, social and governance responsibility policies:
- ISO 14001 (environment), ISO 45001 (occupational health and safety) and Life Cycle Assessment (LCA) certifications.
- Carbon footprint registration and REDUZCO seal from the Ministry for Ecological Transition.
- Adherence to the United Nations Global Compact.
- Internal policies on sustainability, ethics and quality.
- Clear emission reduction targets for 2030 and 2050.
- Projects under development for ISO 50001 (energy management), Waste 0 and EcoPassport certifications.
These actions ensure that the Peritus OLTC Transformer not only meets technical requirements, but also fits into a framework of environmental respect and social responsibility.
IMEFY, through its experience and collaboration with major players in the sector, continues to innovate to offer products that promote an efficient, sustainable and environmentally friendly energy transition, responding to current and future market challenges.
