GE MIGIIQI55E00HI00

Description

Functional Features

• Comprehensive Protection Functions: It includes negative sequence, thermal image protection, three – phase time – over – current, phase instantaneous over – current, ground time – over – current, ground instantaneous over – current, under – current, start – up times/hour and start – up interval time protection functions.
• Flexible Configuration: It has two setting groups, which can provide two protection functions at the same time. It also has configurable logic, curves, digital I/Os, and LEDs. There are 4 pre – configured over – current curves (ANSI, IEC) to choose from, and the user can also configure the over – current curve to achieve precise matching with other equipment.
• Event Recording and Oscillography: It can store up to 24 time – stamped events with a millisecond – level accuracy. It can also capture current waveforms and digital channel data at a speed of 8 samples/cycle, and the oscillography record is up to 24 cycles.
• User – friendly Interface: The 2×16 – character LCD display can show measured data, fault reports of the last 5 trips, and setting values. The front – panel keyboard can be used to modify LED colors and perform other operations.
• Remote Monitoring and Control: It is compatible with EnerVista software, which can be used for setting, monitoring, and remote access, enabling operators to adjust settings, retrieve data, and perform diagnostic tests without on – site intervention.

Application Scenarios

• Generator Protection: It is mainly used for the protection of small – scale generators, providing three – phase and ground protection to ensure the safe operation of generators.
• Motor Protection: It can also be used for motor protection, especially in the application scenarios of motor – driven generator excitation systems (backup/important power supplies).
