Different types of transformers are available in the industry. Voltage transformers and current transformers are among the two most used equipment. The roles of both these transformers are different and have their own importance in the industry. Let’s take a look at what a voltage transformer is and then we will explore current transformers.
Voltage Transformers
Voltage transformers are a type of transformer that is used to step down and decrease the voltage of a system to a safe level. They function by letting energy meters monitor the operation of electrical connections that may have a higher voltage than usual requirements to operate efficiently.
Depending on the use of the application, these transformers can be used as low voltage transformers or high voltage transformers.
- The role of the voltage transformer includes measuring the consumed energy by applications
- It prevents disturbances and faults in the electrical systems, thereby protecting the expensive machines
- Voltage signals can be used to synchronize, events logging, and record events.
- These transformers can isolate the high voltage from electricians using the PT
More importantly, these transformers have the quality of converting high voltage into a standard secondary voltage of 100V or lower. This allows safe and secure use of protective and measuring devices.
Current Transformers
A current transformer is a type of transformer that is designed to produce an alternating current (AC) in its secondary, which is proportional to the AC current in its primary. In other words, this machine can step down or reduce current levels from thousands of amperes to a standard level, either 5 Amps or 1 Amp which ensures normal operation. This transformer is used when a voltage or current is too high for measuring directly.
Primarily, the current transformer is of three types.
Wound Type:
This type of current transformer consists of two separate windings, primary and secondary. These windings are available on a magnetic steel core with different turns, depending on the design
Toroidal (Window) Type:
This type of current transformer comes with no primary winding. Instead, it has an opening in the core. Through this core, the conductor that carries the primary load current is passed.
Bar Type:
Bar type current transformer utilizes the bus bar of the main circuit as the primary winding, which is equal to a single turn. It is completely insulated from the high operating voltage of the system and is generally bolted to the current carrying device.
Both voltage transformers and current transformers play important roles in the industry. You can choose either of the two depending on your requirements. Macroplast is an ISO 9001:2015 certified Transformer Company in India that manufactures, designs, and tests high-quality transformers. The company manufactures Power Distribution Transformer according to the specifications of clients and national and international standards.
