What do you know about CT, PT and CVT with breif description of each equipment?

Question

Accepted Answer

CT, PT, and CVT are electrical equipment used in power systems for measurement and protection purposes.

CT stands for Current Transformer, which is used to measure and step down high currents to a safe level for measurement or protection devices.
PT stands for Potential Transformer, which is used to measure and step down high voltages to a safe level for measurement or protection devices.
CVT stands for Capacitive Voltage Transformer, which is used to measure high voltages and provide isolation between the high voltage system and the measuring or protection devices.
CTs and PTs are commonly used in combination to provide accurate measurements of current and voltage in power systems.
CTs and PTs are essential for various applications such as metering, relaying, and protection schemes in electrical substations.
