Bus type current transformers (CTs) are an essential part of industrial electrical systems. They are used to address the large currents in order to measure and control the system. Bus type CTs are used in a variety of settings, including in power systems, to measure current in high-voltage systems, and to ensure safety in areas with potentially hazardous settings.

Bus type CTs can measure both AC and DC current, as well as symmetrical and asymmetrical currents. The CT is designed with a small cross-sectional area so that it can measure higher currents without the need for large cables. It is also simple to install, as it has only two connections, one for the primary and one for the secondary.

In order to get accurate measurements, the primary current must remain constant, so in some systems, a shunt is used. The shunt is placed in series with the device to be measured, providing a constant current for the CT to work with.

The output of a bus type CT can be in the form of voltage, current, or power. This output can then be used to control the system and take measurements. For example, the output of the CT can be used to control the switching of motors in order to protect them from overvoltage or undervoltage.

In summary, bus type current transformers are essential components of industrial electrical systems. They are used to measure and control large currents, and the output can be used to control other components of the system.
