NDFA-Ⅵ Volt-Ampere Characteristic Comprehensive Tester

Product Introduction

   This product is a fully automated CT Characteristic Tester, designed as a specialized testing instrument for relay protection and high-voltage insulation applications. The instrument can perform tests including: CT/PT volt-ampere characteristic test, CT/PT ratio and polarity test, CT/PT polarity test, CT primary current flow test, CT AC withstand voltage test. It automatically calculates result parameters such as knee-point voltage and current values, ratio error, 5% or 10% error curve values, and more.

   The instrument comes with a built-in mini printer for immediate printing of test data and curves. It is a fully-featured, professional testing instrument suitable for both laboratory and on-site testing, widely praised by users.
