The given transformer is step down transformer because the output voltage is less than input voltage.
A transformer designed to reduce the voltage from primary to secondary is called a step-down transformer. The transformation ratio of a transformer will be equal to the square root of its primary to secondary inductance (L) ratio.A transformer converts alternating current (AC) from one voltage to another voltage. It has no moving parts and works on a magnetic induction principle; it can be designed to "step-up" or "step-down" voltage. So a step up transformer increases the voltage and a step down transformer decreases the voltage.
A Step down Transformer is a type of transformer, which converts a high voltage at the primary side to a low voltage at the secondary side. If we speak in terms of the coil winding, the primary winding of a Step down Transformer has more turns than the secondary winding.It is used in the main adapters and chargers for cell phones, CD players and stereos. It can be used to step down the voltage level in transmission line. In welding machines it is used in reducing voltage and increasing current.you can use a transformer in reverse. The no part has to do with the transformer's design. Secondary or output windings are low impedance to reduce losses and increase efficiency. ... You would need a transformer designed to step up 415V to 11kV.
To conduct this test, the transformer must be completely disconnected, and you need to set the multimeter to read resistance in ohms (Ω). Touch the meter leads to the two input terminals of the primary coil (they may be marked H1 and H2) and check the reading.
- Transformer size is determined by the kVA of the load.
- Load voltage, or secondary voltage, is the voltage needed to operate the load.
- Line voltage, or primary voltage, is the voltage from the source.
- Single-Phase has two lines of AC power.
