If the secondary winding of CT is opened when primary coil is carrying current

Electronics and Communication Engineering (ECE) : Measurements and Instrumentation - Quiz(MCQ)

transformer will burn immediately

there will be weak flux density in core

there will be high current in secondary

there will be very high induced voltage in secondary

Correct Answer : Option (D) : there will be very high induced voltage in secondary

Explanation : Since the primary of CT always remains excited, a high voltage is induced in secondary if the secondary is opened.
