What is the current transformer?
The current transformer is a device used to measure electricity. Electric current is usually distributed at high voltage levels that are dangerous to human beings. The current transformer allows you to measure the current without overruning the current into the measuring device that could be risky for both the device and the person holding it. This is usually achieved by measuring the magnetic field created by a current rather than the current itself. Direct current is generally used in battery devices, including most cars. Power plants use AC current to supply electricity to distant locations, as electricity in this form can be sent over long distances without significant energy loss. High -line direct current lines achieve the same target. Both forms differ from static Elections, which naturally occurring electricity, which is too irregular to be used as a source of energy.
The high voltage used in the delivery of power is dangerous to everything that is not specially created to perform such a voltage. Measuring devices, even if they are insulated to protect users, could easily be damaged by fluctuating high -line electric current. The current transformer eliminates this danger by providing accurate measurement without direct connection to the current itself. The current transformer also allows standard measurements from a wide range of different power devices. The current used in energy supply systems may vary from device to device, so standard measurements are important for efficient management of complicated systems.
Most power transformers are connected to the energy supply system, such as transformers that reduce the high voltage from the electrical lines to the safe level of use of the household. However, the current transformer does not require a physical connection to the measured line. All devices carrying electric current are created by magnetia bunch of fields. The current transformer uses this magnetic field to create a current directly proportional to the measured device or line. For example, a 400-on fee can create a 4-Amp reading. A tool user knowing that the ratio is 1: 100 can derive the actual current of the device.
The current transformer is an important tool in electrical engineering. For safety and efficiency purposes, current levels must be monitored. Measuring devices connected to current transformers allow this monitoring at different locations throughout the system. They can also be used to measure the electrical use of the building for billing or inspection purposes.
