Energy storage device - reduce the cost of distribution transformer loss and reduce the cost of power failure

Reduce the cost of distribution transformer loss The loss of the transformer mainly includes no-load loss and short-circuit loss (load loss). No-load loss, also known as iron loss, is the loss generated when the magnetic flux changes periodically due to the excitation current in the iron core under the rated voltage of the transformer, so […]
