The role of Electrical Current Transformer in variable frequency power supply
Jul 21, 2021| (1) Isolate high-voltage circuits. There is no electrical connection between the primary side and the secondary side of the Electrical Current Transformer, only a magnetic connection. The secondary device is isolated from the high voltage part, and the secondary side of the Electrical Current Transformer is grounded to ensure the safety of the device and the human body.
(2) The large current of the primary circuit becomes the small current of the secondary circuit standard, so that the measuring instruments and protection devices are standardized, small, light in structure, cheap, and the screen is easy to install.
Electrical Current Transformer is an electrical device that converts a large current into a small current. The number of turns of the primary coil is small and is connected in series in the circuit of the measurement circuit. The number of turns of the secondary coil is large, and the meter and the protective relay for measurement are connected in series. Supply measurement and protection. The performance of the transformer directly affects the measurement of the power system, the accuracy of the measurement and the reliability of the action of the relay protection device.
Use of Electrical Current Transformer: The main purpose of Electrical Current Transformer is to transmit BAT54-04 AC current information. Measuring Electrical Current Transformer transmits current information to measurement indicating circuits and meters, and protecting Electrical Current Transformer transmits current information to protection control circuits and devices.
