Arc-flash analysis on a.c. and d.c. output of Phenix Motor Test Set Model No. MTS1000R 750X
Arc-flash analysis on a.c. and d.c. output of Phenix Motor Test Set Model No. MTS1000R 750X
(OP)
Has anyone done an arc-flash hazard analysis on the variable voltage a.c. and d.c. output of a Phenix Motor Test Set Model No. MTS1000R 750X.
Although I have a schematic showing location of the integral protective devices, I have been unable to obtain their type, rating and operating characteristics which is requried to determine the duration of an a.c. or d.c. arcing fault on the output circuits.
Another problem is running a d.c. arc-flash analysis using SKM/PTW software which does not refer the d.c. arcing current on the rectifier d.c. side to the protection device on the a.c. side of the rectifier.
Attached is a schematic diagram showing the a.c. output of the Phenix Motor Test Set Model No. MTS1000R 750X. If required I can send a schematic of the d.c. output.
