Caused by blown fuse on flow comparator of steam generator B coincident w. The AF0500 is a microprocessor-based arc-flash protection relay that limits arc-fault damage by detecting the light from an arc flash and rapidly tripping the feeder breaker. Caused by incorrect setting of relay on 4,160- volt bus C.Auxiliary feedwater. The integrated programmable logic functions (continuous function chart CFC) offer the user high flexibility so that generators, motors and transformers adjustments can easily be made to the varying power station requirements on the basis of special system conditions. 1 NO/NC for generators for electric motors.
Each sub case contains a complete protection device with DC/DC converter for power supply, Potential and current transformers, A/D converter, computer chips, watch dog circuit and trip relays.
The SIPROTEC 7UM62 includes all necessary protection functions for large synchronous and asynchronous motors and for transformers. The generator protection and synchronizing cubicles will be delivered in fully wired and tested cubicles, ready for connection. Private power stations using regenerative energy sources such as wind or biogases They integrate all the necessary protection functions and are particularly suited for the protection of : Low Voltage Products and Systems Busway and Cable Support Circuit Breakers and Switches Contactors and Protection Relays Electrical Protection and Control.
