Low Tension Current Transformer

الوصف

It is not possible to use line current directly for measurement and relaying purpose due to its high value and insulation problem. CURRENT TRANSFORMER is a piece of electrical equipment which converts line current values which are suitable for the devices to which is connected e.g. measuring instruments, meters, protection relays.
 

BASIC FUNCTIONS OF CTs ARE :

•  

  To reduce line current to a value which is suitable for measuring instruments, relays etc.

•  

  To isolate the measuring instruments, meters, relays etc. from line voltage of an installation.

•  

  To protect measuring instruments against short circuit currents

•  

  To sense abnormalities in current and give current signals to protective relays to isolate the defective system.
