Current transformer is used to step down the higher current in primary and protects the measuring instruments against high currents. Low Voltage Transformers are used for supply to measuring instruments & protection devices of electrical switchgear and control gears installation. They are suitable for system voltage 415/660V & Frequency 50/60 Hz. These Current Transformers are designed for a secondary current of 1A or 5A and the primary current ranging from 5A to 7500A depending on the application of the system load current.
