Tips: The difference between no-load and load transformer

The main difference between no-load operation and load operation of the transformer is mainly reflected in the secondary line state. The secondary line of the transformer load operation is connected to the load, and the generated power is large.

The transformer uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for voltage rise and fall, impedance matching, and safety isolation. When the transformer is running at no load; only no-load loss, that is, iron loss and stray, is consumed, which is 6% of the total capacity, and when the load is running, it is no-load loss + load loss, that is, copper loss, which is the total consumption of the transformer.

Existing reviews of 20kVA 440V to 120V/240V Split Phase Transformer

Is your isolation transformer bi-directional?

For example, if your transformer is to convert 3ph, 220V primary to 3ph, 400V secondary, and I apply 3ph, 400V at secondary side, will I get 3ph, 220V at primary side?

ATO Responded

Our isolation transformer can be used in both directions, but the output voltage will be reduced by 2% in case of reverse. For example, the voltage of 220V will become 215V.

Doubts about isolation transformer

Will the output/input voltage of your isolation transformer be set from the factory or can we change it to some other value?
