VAMP RANGE // VAMP 125 ARC PROTECTION UNIT Traditional time-grading or blocking based system may not be suitable to address fast answer in the event of a detected error in the installation. Further, high-impedance type earth-faults may cause prolonged operation times of earth-fault relays leading to the significant release of arcing energy. These facts pose a considerable risk to operation personnel and economical assets. Highest risk for the arc flash phenomena occurs during commissioning and maintenance of the power system and after possible recommissioning of the power distribution...
