GE Multilin EP5P5G5HNNAANGMSFB3ASNBN

The EP5P5G5HNNAANGMSFB3ASNBN is a digital generator protection relay from GE Multilin 889 series, designed for comprehensive protection, metering and control of synchronous generators in power plants and industrial power systems. This EP5P5G5HNNAANGMSFB3ASNBN integrates multiple protection elements such as overcurrent, negative sequence, loss of excitation, stator ground fault, overvoltage and undervoltage protection to guard generator units against diverse electrical faults. The EP5P5G5HNNAANGMSFB3ASNBN supports RTD temperature monitoring, which tracks winding and bearing temperature and provides early warning for overheating risks.

This EP5P5G5HNNAANGMSFB3ASNBN carries flexible digital and analog I/O channels, enabling breaker control, alarm output and signal acquisition for auxiliary equipment. The EP5P5G5HNNAANGMSFB3ASNBN supports mainstream communication protocols including Modbus, DNP3 and IEC 61850, allowing seamless connection with SCADA, substation automation and remote monitoring platforms. It features built-in fault recording, event sequence logging and oscillography functions, helping engineers analyze fault causes quickly after abnormal trips. The human-machine interface on the EP5P5G5HNNAANGMSFB3ASNBN supports local parameter setting, real-time value viewing and fault code checking for on-site commissioning.

The EP5P5G5HNNAANGMSFB3ASNBN is widely deployed for small and medium-sized synchronous generators in hydro, thermal, biogas and cogeneration power stations. This EP5P5G5HNNAANGMSFB3ASNBN follows global power protection standards and is built for long-term stable operation in harsh substation environments. Original factory production of this EP5P5G5HNNAANGMSFB3ASNBN has been phased out, and available units are mostly surplus spare parts for generator panel retrofit and emergency replacement of existing 889 protection systems.
