The paper is not an in- depth analysis of Modbus protocol structure and physical connections. Rather, because Modbus Use the SEL-451-4 with the SEL-2600A RTD Module for dynamic overload protection using SELOGIC control equa-tions. Rules-Based Settings Editor. Communicate with and set the relay using an ASCII terminal, or use the PC-based ACSELERATOR® QuickSet™ SEL-5030 Software to configure the SEL-451-4 and analyze fault records with relay element response.

You can use the SEL-751 directional and non-directional overcurrent functions to protect virtually any power system circuit or device including lines, feeders, transformers, capacitor banks, reactors, and Aventri - Client Login the SE-701 will remain tripped, with the trip relay de-energized and the TRIP LED on, until reset. In the non-fail-safe mode, the output relay energizes when a ground-fault trip occurs. In the non-fail-safe mode, trip status is not retained in non-volatile memory. 2.1.2 TRIP INHIBIT Switch 2 is used to select Class I or Class II operation. SEL-311L Relay contains all the protection, control, and communication features available in the SEL-311C Relay including distance, directional, and nondirectional overcurrent protection; under- and overvoltage and frequency protection; and multishot reclosing. The SEL-311L Relay implements line current differential protection using communications Figure 6 shows an SEL-2505 application using existing distribution relays and a SEL-2100 Protection Logic Processor to provide bus and line protection for the radial system. When the overcurrent elements of the transformer low-side relay pick-up and the overcurrent elements in the feeder relays do not, the detected fault must be located on the bus.
