Transformer secondary side is high pressure or primary side is high pressure
Step-up transformer secondary side is the high-pressure, step-down transformer primary side is high pressure.
Step-down transformer primary side is high pressure, secondary side is low pressure. The step-up transformer is just the opposite. Step-down transformer reverse use is the step-up transformer.
Transformer can be divided into two types of step-up transformer and step-down transformer, the primary side of the transformer is the voltage input, the secondary side is the output. Step-up transformer is the secondary side voltage greater than the primary side, step-down transformer is the secondary side voltage is less than the primary voltage.
