Unlike liquid fill transformers that require oil or liquid to cool, dry type transformers use only high temperature insulation systems that are environmentally safe. Dry type transformers are static solid state devices with no moving parts, which require minimum maintenance and provide a long reliable trouble-free life. Because they are completely hazard-free, these transformers can be easily installed in hospitals, schools, factories, chemical plants and buildings where fire safety is a great concern. They can be easily installed indoors as well as outdoors only confirming that there is enough ventilation. However, one drawback with these transformers is that they are easily affected by dirt, dust, moisture and corrosion because the windings are exposed to air. Therefore, these transformers need to be periodically cleaned to prevent dust and other contaminants to build up over time.
How does electricity travel from the generator into the homes of people residing in the city? Have you ever thought about it? Electricity is required to travel long distances through wires that are exposed to all sorts of climates all-round the year. Electricity also produces a lot of heat, much of which is wasted during the entire process. This is why when it starts its journey from the generator; it should be changed into high voltage by Toroidal power transformers. More than 50 thousand volts of high voltage electricity travels in every wire across the world. When this electricity reaches the city, it gets deviated into low voltage transformers.
Low voltage lighting is energy-efficient, flexible and safe, and is highly popular for usage in lanterns, task lighting and accent lighting. If you are planning to install low voltage lighting in or around your home, you can do so easily. Below are the steps you need to follow to do so.
Electrical transformers have become a part of all modern industries, automation industries, textile industries, refrigeration industries, and all processing industries. In fact, no industry can be imagined without transformers today because every industry has some or the other machinery involved, and no machine can be directly connected to National grid/power supply or work on high tension lines.
Three-phase or 3-phase supplies are used for electrical power generation, transmission and distribution. They have many advantages over single-phase supply and thus, are highly used in industries. 3-phase transformers have to deal with three alternating currents and voltages. A transformer cannot change single-phase to 3-phase or vice-versa. To make the transformer connections compatible with 3-phase supplies, they need to be connected in a particular pattern to form a 3-phase transformer configuration. In a 3-phase transformer, three primary windings of three single-phase transformers are connected to one another and three secondary windings are inter-connected in a fixed configuration to get a 3-phase supply.
