GE SR750-P5-G5-S5-HI-A20-R-T Power protection relay
GE SR750-P5-G5-S5-HI-A20-R-T is a power protection relay used to monitor and protect equipment and lines in power systems. The following is an explanation of each parameter in this model:
P5: Indicates that the relay can monitor the voltage of the power grid, including the magnitude, phase, and frequency of the voltage.
G5: Indicates that the relay can monitor the frequency of the power grid, including the magnitude and deviation of the frequency.
S5: Indicates that the relay can monitor the synchronization of the power grid, including phase, frequency, frequency deviation, and phase deviation.
HI: This relay can monitor ground fault currents in the power grid and timely isolate the power system from faults to protect the safety of personnel and equipment.
A20: Indicates that the relay has 20 analog input channels, which can monitor and record various parameters of the power system, including current, voltage, power, etc.
R: Indicates that the relay has a recording function that can record fault events and operating data occurring in the power system for analysis and diagnosis.
T: Indicates that the relay has a communication interface that allows for data exchange and remote control with other devices.
In summary, the GE SR750-P5-G5-S5-HI-A20-R-T relay can comprehensively monitor and protect the power system, including recording and communication functions for voltage, frequency, synchronization, ground fault current, and various parameters.
