NAKFR Transformer unloaded &loaded characteristic tester

Product introduction

NAKFR transformer unloaded &loaded characteristic tester is dedicated to the transformer unload loss,short-circuit loss , zero sequence impedance,short-circuit impedance of the instrument,unload loss and short-circuit losses are generators,motors,transformers trials important items; according to GB1094.5-85 and IEC14/268CD regulations,changes in the amount of short-circuit impedance transformer winding is to determine whether the deformation of the sole criterion.The instrument circuit design is exquisite,unique ideas,making its performance is superior,powerful,small size,light weight,extremely easy to use site.The internal instrument uses advanced multi-A / D Synchronous AC sampling and digital signal processing technology,the successful solution of the low power factor measurement and multi -channel signal in the city,under the conditions of simultaneous measurement and calculation of the problem, and the multiplier power measurement technology has significant advantages over,NAKFR transformer no-load load Tester easy operation , accurate and reliable data that can completely replace the traditional instrumentation of the test method,the user can display and record all measurement data concerned,can be used as on-site precision AC indicating instrument used. Use instrument can greatly improve efficiency, reduce labor intensity.
