A CT/PT analyzer, also known as a current transformer/potential transformer analyzer, is a test system used to evaluate the performance of current transformers (CTs) and potential transformers (PTs) according to industry standards, such as IEC and IEEE standards. CTs and PTs are instrument transformers that are commonly used in power systems for measurement and protection purposes. A CT/PT analyzer can measure various parameters of CTs and PTs, such as polarity, ratio, burden, and accuracy, and can help ensure that these transformers are operating correctly and accurately. CT/PT analyzers are commonly used by engineers and technicians in electrical power utility companies, manufacturers of power transformers, and testing and calibration laboratories.
