The Total Phase Advanced Cable Tester - Level 1 Application provides continuity testing, DC resistance measurement, and E-Marker verification. The Total Phase Advanced Cable Tester - Level 2 Application provides additional capabilities to evaluate cable signal integrity at up to 12Gbps. Both ...
Regarding the test procedure this proposed development test follows strictly IEC 61238-1-3 in order to use the same requirements for performing the test and by using the same concept of “reference method”. That means, that the test can be done by using different parameter if adequate, as ...
First, a stiffness matrix of the cable-pulley assembly is calcu- lated according to a strictly formal procedure based on the potential energy of all cable segments. The resulting stiff- ness matrix couples both deflections of the interface points (between the cable system and the attached ...
First, we describe the experimental bench used at laboratory-scale and the set-up designed to prevent unscrewing when testing cable bolts. Then, we present the samples preparation procedure, as well as the main characteristics of the bolts, the grouting materials and the rock type used to ...
