How to safely isolate a circuit
WebAnd for some capacitors, this failure mode can result in a short circuit condition; abruptly ending its isolation-ability, as well as possibly rendering its circuit unsafe or hazardous. Safety rated Y-type capacitors are used in line to ground applications and are designed to fail open; while X-types are used in line-to-line filtering applications and may fail short. Web26 jan. 2006 · Posted January 26, 2006. Hi, It is not advisable to isolate the output of a variable speed drive through a power isolator or a contactor. We are working on a project where there are quite a few conveyors which would be VSD driven. The plant manager is requesting an isolating medium near the conveyor for security purpose during maintenance.
