IEC60044-6 CT and PT Analyzer CT Polarity Tester PT Test Set for Excitation Curve Test

Product Description

 IEC60044-6 ct and pt analyzer CT Polarity Tester PT Test Set for Excitation Curve Test


Overview

CT & PT Analyzer is a high-performance, portable testing device engineered for the thorough evaluation of Current Transformers (CTs) and Potential Transformers (PTs). It combines advanced measurement technology, an intuitive design, and durable construction to address the demanding testing requirements of power systems, industrial facilities, and electrical engineering projects.
