General introduction

GDKC-6A Circuit Breaker Tester is used to test the dynamic characteristics of high voltage and low voltage circuit 

breaker. It has features easier operation and higher accuracy comparing to traditional device.

Features

• 5.7inch touch screen.
• Thermal printer.
• 6 channels contacts,1channel velocity test
• Test 1channel current of CLOSE/OPEN coil.
• In Routine test, CLOSE-OPEN time, bounce Time, synchronization time can be tested.Also CLOSE-OPEN velocity, Max.velocity, average velocity, stoke distance, over-travel, total travel can be measured.
• In reclosing test, OPEN-CLOSE,CLOSE-OPEN,OPEN-CLOSE-OPEN time can be tested.
• In Low-voltage test, Voltage Operate value of CLOSE-OPEN coil can be tested. Power supply voltage can be adjusted continuously.
• Three kinds of CLOSE-OPEN control modes.                                                                     
•     Internal Control. Inner power supply will supply DC voltage with CLOSE-OPEN coil.                           
•     External Control. External power supply will supply AC voltage with CLOSE-OPEN coil.                        
•     Idle contact Control. Built-in 2 channels passive idle contacts.
• Contact status-Time curve, Travel-Time(S-t) curve, Coil current-Time(I-t) curve can be recorded. It is convenient to determine fault of circuit breaker.
• USB interface for connecting with PC.
• EXCEL format data can be exported.
• With dust-proof and waterproof sealed plastic carry case.
