Today, We will learn about What are voltage transformers?, What is the voltage transformer?, What are the three types of voltage transformers?
What are voltage transformers?
Voltage transformers, also called potential transformers or VTs, are electrical devices used to transform high voltage levels to lower, more manageable levels suitable for measurement or control purposes. They are commonly used in electrical power systems for measurement, protection and monitoring applications.
What is the voltage transformer?
Voltage transformer, also called TV or potential transformer, is a specific type of transformer designed to accurately exceed high voltages to lower, standardized levels suitable for measuring or protection devices. These transformers ensure that voltage levels supplied to instruments or equipment are within safe and manageable ranges.
There are three main types of voltage transformers: electromagnetic voltage transformers, capacitive voltage transformers and optical voltage transformers. Each type has its own unique design and operating principles, addressing different applications and requirements in electrical systems.
What are the three types of voltage transformers?
Voltage transformers and current transformers (CTS) are both essential components in electrical power systems for measurement, protection and control functions. While voltage transformers step down high voltages to lower levels, current transformers step down high currents to manageable levels for measurement and protection devices.
The principle of work of a voltage transformer (VT) is based on Faraday’s law of electromagnetic induction. When a varying voltage is applied to the primary winding of the transformer, it induces a proportional voltage in the secondary winding due to mutual induction. This secondary voltage is then used for measurement, control or protection purposes in electrical systems.
