CT PT Tester Transformer Characteristic Analyzer 180Vrms 12Arms Ratio 1-40000 | XHTX206

The XHTX206 CT PT Tester is a comprehensive transformer characteristic analyzer for the power industry, built on a high-performance DSP and FPGA platform with advanced frequency conversion testing technology. It covers excitation (volt-ampere) characteristics, transformation ratio, polarity, secondary winding resistance, secondary load, ratio error and angle error testing for protection-class, metering-class and TP-class current transformers, and supports excitation characteristics, transformation ratio, polarity, secondary winding resistance and ratio error testing for PT electromagnetic units. As a new-generation instrument developed through extensive market research and theoretical study, it replaces the traditional combination of variable-ratio transformers, step-up transformers and current boosters, delivering higher automation, better stability and significantly improved testing efficiency for professional transformer verification.

With comprehensive CT/PT testing capability, frequency conversion technology and automated reporting, the XHTX206 delivers laboratory-grade precision and field-ready convenience for transformer characteristic analysis. The instrument's advanced self-test and through-flow test functions further extend its value for commissioning teams, enabling complete verification of the whole measurement chain before formal testing begins.

The XHTX206 follows the low-frequency method test principle for excitation characteristic testing, which significantly reduces the required test voltage and current while preserving measurement accuracy. The instrument also applies the 10% error curve calculation method to evaluate the performance of protection-class current transformers, helping engineers verify that protection devices will operate correctly under fault conditions. All tests comply with GB1208 (IEC60044-1), GB16847 (IEC60044-6) and GB1207 standards, and the instrument automatically selects the appropriate standard according to the transformer type and class, ensuring consistent, repeatable results that are accepted by utilities and third-party laboratories worldwide.

For various CT structures including bushing-type, wound-type and window-type current transformers, the appendix of the manual provides detailed four-terminal wiring diagrams, guaranteeing correct connections for accurate measurement in every configuration. The instrument's self-test function verifies internal circuits and measurement channels before testing, while the through-flow test function validates the complete current loop, making the XHTX206 a complete verification solution for transformer testing professionals.
