BESS Transformers
BESS transformers are designed to interface Battery Energy Storage Systems with the medium voltage utility grid. These transformers operate in bidirectional mode, handling both charging and discharging cycles from the Power Conversion System (PCS), and must withstand frequent switching, fast transient harmonics, and nonlinear loads.
TEK Transformatör designs BESS transformers with low impedance, high thermal endurance, and harmonic-robust winding construction, ensuring stable operation across all modes. Units are available from 250 kVA to 5000 kVA, with customized voltage ratios and can be equipped with electrostatic shields, K-rated windings, and smart monitoring systems for grid tied or islanded BESS configurations..-
Design options:
- Designed for both step-up and isolation configurations
- Suitable for central PCS, string inverters, or modular BESS skids
- Hermetically sealed or conservator-type tank options
- Compatible with air-insulated or gas-insulated switchgear integration
- Built to withstand repetitive switching surges, transient overvoltages, and fast ramping
- Engineered for nonlinear current profiles from PCS and inverter switching
- Optional K-factor rated windings
- ONAN, ONAF or KNAN cooling systems tailored to frequent load cycling
- High thermal reserve for overloads during grid charging/discharging peaks
