HDZK Transformer Short Circuit And Impedance Tester

General Information 
Low voltage short circuit impedance test is to identify the shock of short circuit on the transformer on the operation, which is the direct method of checking the winding distortion after transformers hit by mechanical forces during transportation and installation.
Short circuit impedance test is an important parameter to decide the running or disassembling inspection for transformer .
Transformer Short Circuit And Impedance Tester is a new development instrument suitable for testing low voltage short short circuit impedance 35kV transformer in the field and labor.
● Automatically perform three phase or single phase measurement by one-time connection and display directly the measurement result.
● Internal power and external power can be as measurement supply power : internal power is working power of instrument, external power can be output by voltage regulator .
● High-speed A/D synchronous sampling technology makes test result of transformer impedance with accuracy and repeatability.
● Adopts 320X240 large LCD screen with easy operation.
● Built-in large capacity nonvolatile storage and 2000 measurement data storage.
● Built-in high accuracy real-time clock function: data and time calibration
● Built-in high speed thermal printer:measurement and history data printing
● Built-in USB controller: measurement data can be permanently saved by U disk in the computer.
● Perfect circuit protection with strong interference and high reliability .
