What is a voltage transformer used for?
A voltage transformer, also called a potential transformer, is designed to reduce high voltages to lower, more manageable levels for measurement and monitoring purposes. It lowers the voltage to a lower level that can be safely used by standard measuring instruments, such as voltmeters and wattmeters. Voltage transformers are essential in electrical systems to ensure accurate voltage measurements and provide isolation between high voltage circuits and measuring devices.
A voltage measuring transformer, often called a voltage transformer (VT) or potential transformer (PT), is specifically designed to measure voltage in high voltage systems. It provides a reduced voltage output proportional to the input voltage, enabling precise measurement and monitoring of high voltages using standard measuring instruments. This type of transformer is essential to ensure the safety and accuracy of electrical measurement and monitoring systems.
What is the voltage transformer used for?
The function of a transformer is to transfer electrical energy between two or more circuits by electromagnetic induction, adjusting voltage levels based on the turns ratio of its windings. It can either increase (increase) or decrease (decrease) the voltage from the primary circuit to the secondary circuit. Transformers are used to efficiently transmit electrical energy over long distances and to provide appropriate voltage levels for various applications, ensuring the safe and efficient operation of electrical systems.
Where is a transformer used?
A high voltage transformer operates by using electromagnetic induction to increase or decrease high voltage levels. It consists of primary and secondary windings wound around a magnetic core. When alternating current (AC) flows through the primary winding, it creates a changing magnetic field in the core. This changing field induces a voltage in the secondary winding depending on the turns ratio between the two windings. High voltage transformers are designed to handle and convert high voltage levels safely and efficiently for power transmission and distribution.
A current transformer (CT) measures the current flowing in a conductor by producing a proportionally smaller current in its secondary winding. It provides isolation between high-current circuits and measuring or protection devices, enabling safe and accurate current measurement without directly exposing measuring instruments to high current levels. Current transformers are widely used in electrical systems for monitoring, control and protection purposes, enabling precise measurements and protective equipment.
