Product Description

1. Basic Concept of a Low Voltage Dry Type Transformer

A transformer is an electrical device which uses to modify alternating voltage and current levels. It normally consists of a core, windings, and an enclosure. In low voltage distribution systems, transformers are primarily used to step primary voltage down to an appropriate lower levels, or to convert low current into higher current, so that different electrical equipment can operate with the required power supply conditions.

Functions of a Transformer

1. Voltage Transformation

In low voltage distribution networks, 75 kva step down dry type transformers are mainly used to change voltage levels. For example, some equipment operates on 220 V, while the supply voltage in a typical low voltage system is 400 V. In such cases, a 75 kva step down dry type transformer is essential to reduce the 400 V supply to 220 V.

2. Stepping Down Voltage

75 kva step down dry type transformers can also be used simply to obtain a lower voltage when it cannot be directly provided by the distribution system. If a device requires a specific low voltage level to operate, the 75 kva step down dry type transformer could reduce the higher supply voltage accordingly.

3. Increasing Current

A 75 kva step down dry type transformer can also be used to increase current in a low voltage system. Certain equipment requires a higher current than what the system can provide directly. In these cases, the transformer raises the available current to the level needed by the load.
