Transformers
Distribution Transformer
A distribution transformer is also known as a typical kind of isolation transformer. The main function of this transformer is to alter the high voltage to the normal voltage like 240/120 V to use in electric power distribution. In the distribution system, there are different kinds of transformers available like single phase, 3-phase, underground, pad-mounted, pole-mounted transformer. Generally, these transformers are available in different sizes with efficiencies along with insulating oil.
Power Transformer
Power Transformers are very widely used for stepping up and stepping down the voltage at the electrical power generating station and distribution station or substation respectively. The most important reason for using the power transformer is to reduce power losses during electric power transmission.
Dry Type Transformer
Dry-type transformer is a completely stationary solid-state device and it needs less maintenance to provide problem-free service. This transformer doesn’t contain any moving parts. Unlike liquid fill transformers, this transformer simply use high-temperature insulation systems as they are very safe environmentally. These transformers give a secure and consistent power source that doesn’t need fire-resistant vaults, the emitting of toxic gasses otherwise catch basins.
Cast Resin Transformer
Cast resin transformers represent an alternative solution for electric power distribution in medium voltage applications. The advantages of cast resin transformers in comparison with the traditional oil-filled transformers are minimal fire risk, no cooling liquids, easier maintenance, low operating costs, simplicity of installation & high reliability.
Furnace Transformer
Furnace transformer is a transformer where a furnace melts charged material through an electric arc. Transformers of these types are used in steel melting and metallurgical industry. It can be usually divided into 2 groups: AC Furnace Transformer & DC Furnace Transformer. AC Furnace Transformer can be subdivided into Arc Furnace Transformer and Reduction Transformer.
USS Transformer
Unitized Transportable Substation is used for feeding power from high voltage to low voltage in open cast mines, construction sites, metro cities etc. The substation is compact in size, suitable for frequent shifting and for use in outdoor locations. The substation is installed and mounted on skid frame or wheels or channels and is provided with lifting hooks. The unitized substation comprises of the following main components.
Solar Power Transformer
A solar power transformer is used in solar power applications. A solar panel transformer has to convert the DC voltage coming out of the photovoltaic systems and step it up to the rated output. This can also be called as a solar inverter transformer because it inverts DC to AC. When solar panels are arranged in an array over large areas, the combination is called a solar farm.
Instrument Transformer
Instrument transformers are high accuracy class electrical devices used to isolate or transform voltage or current levels. The most common usage of instrument transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuitry from the high voltages or currents. They are of 2 types: Current Transformer (CT) and Potential Transformer (PT).
Control Transformer
A control transformer is an isolation transformer designed to provide a high degree of secondary voltage stability (regulation) during a short period overload condition typically referred to as inrush. They are usually referred to as CPT’s.
