Current Transformer Testing
Current transformer testing is a critical process in the field of electrical engineering and power systems. Current transformers (CTs) are essential components in power measurement and protection systems, ensuring accurate current readings and enabling the safe operation of electrical equipment. Proper testing of CTs is vital to confirm their performance and reliability.
The testing of current transformers involves a series of assessments, including ratio testing, insulation resistance testing, and burden testing. These tests validate the CT’s ability to accurately transform primary current into secondary current and assess its insulation quality. Moreover, saturation tests and polarity checks are performed to confirm the CT’s response under different conditions.
