High Voltage Switch Tester

HDHL-100/200 Loop Resistance Tester


HDHL-100/200 Loop Resistance Tester

Scope of application

It is suitable for measuring the contact resistance between dynamic and static contacts of power system switch equipment, large cross-section wire contact resistance, the contact resistance value of the main contact of high and low voltage switch, and the measurement of DC resistance value of high and low voltage cable lines.

Performance characteristics

(1) Variable gear power control technology, continuous measurement under selected output current, can visually display the change process of tested resistance;


(2) Automatically identify faults such as virtual connection and disconnection of the test line;


(3) The measuring current and measuring time can be displayed;


(4) Internal overcurrent and overload automatic protection function.
