Current Sense Transformers (CSTs) are essential components used in various electrical applications to measure and monitor electric current levels. They detect the magnetic field produced by the current passing through a wire, allowing for accurate and reliable measurements.

CSTs are made up of a magnetic core with a coil of wire wound around it. As current flows through the wire passing through the magnetic core, it produces a magnetic field that is detected by the coil. The output signal from the coil is proportional to the current flowing through the wire, allowing the current level to be measured.

CSTs provide high accuracy current measurements, enabling precise monitoring and control of electric current levels. They can operate over a wide frequency range, making them suitable for use in a variety of electrical applications. Additionally, they are easy to install and can be easily integrated into existing electrical systems. They are also available in various sizes, allowing them to be used in applications with limited space.

CSTs are used in various electrical applications, including motor control, power supplies, and inverters. They are also used in electrical safety systems to detect overcurrent conditions and trigger safety mechanisms.
