It is important to learn as much as you can about power transformers before your company asks for quotes and begins to look into purchasing one. A transformer is a vital component in power transmission. It can last for up to two decades once it is installed. It is important to make informed and wise decisions. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.
A few things you should know about transformers. First, let’s talk about the voltage. Transformers are available in three voltage ratings. This brief overview should help you better understand each one.
Transformers for high voltage
High voltage transformers deal with voltages that can’t be used by the consumer directly but are used in power transmission applications. The range of electrical energy that high voltage transformers handle is 230,000 to 35,000 Volts. A high voltage transformer must be able to transmit these voltages long distances. This is why it has a different core geometry, winding method, and insulation than low voltage transformers.
Step-up transformers, which can increase the primary voltage from transmission-level high to higher voltage, are high-voltage transformers. Highvoltage transformers can also be used, depending on their location in the transmission chain to step-down voltages. The high voltage transformers have a variety of applications, including power distribution and control, electrical isolation and instrumentation. This type of transformer is also easily configurable from one to three phase.
Medium voltage transformers
This range of transformers is typically used in the local distribution segment of the power supply system. They are used to supply power from local distribution circuits, ranging in voltage from 35,000 volts up to 2,400 Volts. If residential customers are the end users, the output voltage may be as low at 120 volts or as high as 5,000 volts for industrial customers. This transformer is a link between utility providers and end users.
These transformers are often found on utility poles or in green boxes with tamperproof covers for connections in schools, residential subdivisions, mobile homes parks and shopping malls. In recent residential developments, they can even be viewed curb-side right in front of the home. These are the most common of all three sizes and are typically liquid-filled.
Transformers for low voltage
A lowvoltage Transformer, sometimes called a magnetic highvoltage transformer or a lowvoltage magnet transformer, is usually used at the end consumer of the energy grid. A lowvoltage Transformer is a distribution transformer that has both the primary windings and the secondary windings. It is designed to work at low voltage class system voltages. The electronic lowvoltage transformer converts 120 volts into 12 or 24 VDC. To convert its output to DC, a DC low voltage transformer uses an rectifier. This rectifier reduces radio frequency interference (RFI) and converts the DC to direct current (DC). Lowvoltage transformers can be mounted in many different ways and are usually small in size.
