Reliable data transmission via PRP and HSR redundancy protocols.
#SIEMENS GENERATOR PROTECTION RELAY SERIAL#
Up to 4 pluggable communication modules, usable for different and redundant protocols (IEC 6, IEC 6 Client, IEC 63, IEC 64, Modbus TCP, DNP3 serial and TCP, PROFINET IO, PROFINET IO S2 redundancy).
Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE).
Graphical logic editor to create powerful automation functions in the device.
Single-channel parallel connection function (synchronization) with adjustment commands for rotational speed (frequency) and voltage.
Inadvertent energization protection to detect incorrect activation of the circuit breaker.
Protection functions for network decoupling (voltage and frequency protection, directional reactive power undervoltage protection (QU protection) and vector-jump protection).
Overfrequency and underfrequency protection, frequency change protection and monitoring of dwell time in frequency bands as turbine protection (protection against abnormal frequencies).
Universal overvoltage and undervoltage protection with different measuring methods.
Shaft-current protection (in particular with hydropower applications).
Rotor and stator overload protection with cold gas consideration (coolant temperature).
Overload protection and temperature supervision via external RTD unit (with PT 100, for example).
Underexcitation and overexcitation protection.
High-precision reverse-power protection and universal power protection.
Rotor ground-fault protection with different measuring methods (ground current or ground-resistance monitoring).
Stator ground-fault protection (90% non-directional or directional, 100% with 3rd harmonic, real 100% protection with 20-Hz voltage interference).
