The application for capacitor voltage transformers, CVTs, is the same as for Inductive Voltage Transformers. The main function of a Capacitive Voltage Transformer is as follows: To transform currents or voltages from a usually high value to a value easy to handle for relays and instruments.
The burden is the load on the secondary winding of the transformer The capacitive voltage transformer step-down the extra high voltage signals and provide the low voltage signals which can easily measure through the measuring instrument. The Capacitive voltage transformer (CVT) is also called capacitive potential transformer
A Capacitive Voltage Transformer (CVT) works by using a combination of capacitors and a transformer to step down high voltages to a lower, more manageable level for measurement and protection. Here’s a step-by-step explanation of how a CVT works: High Voltage Input: The Capacitive Voltage Transformer (CVT) is connected to a high-voltage power line.
High Voltage Input: The Capacitive Voltage Transformer (CVT) is connected to a high-voltage power line. The high voltage from this line is applied across a series of capacitors, which form a capacitive divider. Capacitive Divider: The capacitive divider consists of two or more capacitors connected in series.
Operating Principle: A Capacitive Voltage transformer works on Capacitor Voltage Divider principle. For better understanding, assume a simple circuit of CVT which is connected between a line of 400 kV and Earth. As the CVT is connected between the line and earth, therefore phase voltage (400/1.732 = 230 kV) will be applied.
Capacitive Voltage Transformers (CVTs) are essential in electrical power systems for several reasons. Firstly, they enable the safe and accurate measurement of high voltages. This is important for monitoring and managing electricity usage, as well as for billing purposes.
