WebThe label on the transformer will give you the volt-amp rating (VA), cycles per second (hertz/Hz), and primary and secondary voltage (s). In the case of the multi-tap primary transformer in this video, you can only use white and one other color (we can’t jumper the other two together, either). WebTransformers are basically inductors: • Increasing frequency increases impedance and lowers current (less flux). • Decreasing frequency decreases impedance and increases winding current (more heat). 4.Voltage The available winding insulation is the governing factor for the voltage rating on the transformer. porthleven wave buoy
