An arc protection relay is a protective device used tomaximize the personnel safety and minimize the materialdamage of the installation in the most hazardous powersystem fault situations. The arc protection system detectsan arc in an installation and measures the fault current. On detection of a fault the arc protection relay immediatelytrips the concerned circuit breaker(s) to isolate the fault.An arc protection system operates much faster thanconventional protection relays and thus damage causedby an arc short circuit can be kept to a minimum level. Modern society heavily depends on an...

The comprehensiveness of an arc protection system depends on therequirements of the customer segment. Each segment prefers using an appropriate protection scheme and the scheme is naturally optimised for the power system. Vamp has designed the arc protection family keeping the requirements of every customer segment in mind. > Cost effectiveness from basic to demanding applicationsՕThe system shall be adaptive to changes during the execution of the switchgear construction projectArc sensors mountable in stagesՕChoice and mixture of sensor technologies (point sensor, fiber sensor)...

Arc Protection Series Arc Protection Series > A unique concept to integratearc protection system and feeder protection relays The VAMP 255 feeder manager receivesits light information via the BIO line fromthe VAMP 221 central unit system. VAMP 255 operates as a back-up protection for the arc protection scheme but in addition to this the feeder manager supervises arc faults in the busductcompartment. The VAMP 221 and VAMP 255 units are interconnected using a standard instrumentation cable. 3-phase current measurement or 2-phase currentand residual current measurement is used when the...
