Product Description

GDHL-600 Customized DC Circuit Breaker Automatic Contact Resistance Tester
 

I. Application 

• High, middle and low voltage circuit breakers
• High, middle and low voltage disconnecting switches
• High-current bus bar joints
• Cable & welding joints

 It is suitable for high current, micro-ohm measurement.
 

II. Features 

• Two test modes: routine test and switch resistance test;
• Continuous output of high current;
• Test time is set at different steps or user-defined;
• With high speed thermal printer, test results are printed real-time;
• User-friendly man-machine interface, resistance, current, voltage, time and status are displayed on the same screen, more intuitive;
• Data storage function. Up to 256 groups of data can be saved and viewed;
• Wiring diagram and chart of referential resistance value for common switches are available;
• High automation and high security, fully touch screen operation;
• Ambient temperature and inner temperature tests are provided to protect the machine from damage;
• Standard resistor is set to compare the measured value and standard value;
• Resistivity at 20ºC is calculated when conductor's length and cross section is set, convenient for user to evaluate the material of conductor.
