Mini Substation transformer

Daelim's Solar Energy Transformer Solution

  • Daelim specializes in transformers for Distributed Photovoltaic (DPV) Power Generation Systems, which convert solar radiation into direct current (DC) electricity using semiconductors that exhibit the photovoltaic effect. These systems typically use solar panels with a combined DC voltage output of up to 1100V (DC).
  • The DC voltage is converted to three-phase AC voltage using an inverter, which is then connected to a DPV system inverter transformer for distributing alternating current (AC) energy.
  • Daelim’s transformers are tailored for applications ranging from residential rooftops to commercial and industrial applications, and utility-grade power plants.

Core Features of Daelim's Transformers

Utilization of FR3 dielectric fluid for enhanced fire safety, equipment reliability, and extended lifespan.

Custom-optimized transformer designs for specific loading profiles, impedance requirements, and inverter connections. Increased overload capability without loss of insulation life.

Compatibility with solar/energy balance of system (BOS) solutions, including a range of electrical components.

Transformer Selection Parameters

Rated output kVA is determined based on inverter output ratings, load diagrams, harmonic content, weather patterns, and service conditions.

Nominal voltage is designed to be compatible with the pulse voltage shape of inverters.

Winding connection diagrams and vector groups are tailored to suit inverter operations. Electrostatic Shields (ES) are recommended between primary and secondary windings to minimize high-frequency voltage disturbances.

Advantages of Daelim's Transformers

Proven experience in supplying projects in North America, with certifications such as UL, cUL, CSA, and SGS.
