These systems make it possible to store energy from renewable sources (wind and photovoltaics) and make it available when needed. Between these energy storage systems and the main grid, galvanic separation of the two circuits was appropriate in order to protect the inverter and batteries from any overvoltages and/or surges generated in the grid.
DAELIM Transformers for application in Battery Energy Storage Systems ( BESS) . A BESS is a type of energy storage system that uses batteries to store and distribute energy in the form of electricity. These systems are commonly used in electricity grids and in other applications such as electric vehicles, solar power installations, and smart homes.
Galvanic Isolation An isolation transformer transfers electrical energy through magnetic induction. Due to this physical separation of the primary and secondary windings, any fault in the primary circuit does not directly affect the secondary circuit.
The 2023 National Electrical Code defines an isolation transformer as follows: Isolation Transformer. A transformer of the multiple-winding type, with the primary and secondary windings physically separated, that inductively couples its ungrounded secondary winding to the grounded feeder system that energizes its primary winding. Why isolation?
