Arcing contact diagnostics of the LTB145D1/B circuit breaker with the DCRT-200 and the PKV/M7

DCRT-200 – Dynamic contact resistance tester which is designed to determine the state of the arc extinguish chamber of SF6 circuit breakers by DCRM method (dynamic contact resistance measurement). 

The DCRT-200 is a complementary accessory that extends the functionality of the PKV/M7 device for circuit breaker diagnostics.

This video presents measurement process of the LTB145D1/B high-voltage circuit breaker using the DCRT-200 and PKV/M7 devices through the special PC software.

The following video was filmed at the Rosseti Lenenergo training facility.
