The GE F650BABF1G0HIE is a digital bay controller or medium-voltage protection relay from GE Multilin's 650 series. While detailed parameters for this exact model are not fully available, the following specifications are based on the characteristics of products within the same series:
- Overcurrent Protection
- Features instantaneous and time-delayed overcurrent functions for phase, neutral ground/sensitive ground. The time-delayed overcurrent function can also be applied to negative-sequence current, supporting multiple time curves (IEEE/ANSI, IEC, etc.).
- Directional Elements
- Directional functions are available for phase, neutral ground, and sensitive ground currents. Neutral/ground directional elements can operate under zero-sequence voltage, ground sensitive current, or dual-polarization conditions.
- Voltage Protection
- Provides phase/auxiliary overvoltage, undervoltage, neutral overvoltage, and negative-sequence overvoltage protection.
- Frequency Elements
- Equipped with three separate frequency units that can be set for underfrequency or overfrequency protection, typically used in load rejection scenarios.
- Circuit Breaker Failure Protection
- If the trip command sent to the circuit breaker is not executed within the specified time delay, the device will send an additional trip signal to trip all circuit breakers on the same bus. It includes settings for two-stage current and two-stage delay.
- Automatic Reclosing
- Applicable to three-phase trip schemes and single circuit breaker applications. The automatic reclosing output can modify the loop protection settings between each closing operation.
- Setting Groups
- Can store three separate protection setting groups.
- I/O Interfaces
- Typically offers 16–32 inputs and 8–16 outputs for selection. Digital inputs are customizable with individual debounce and vibration delay functions.
- Human-Machine Interface (HMI)
- Equipped with a graphical HMI for accessing monitoring, measurement, and alarm screens.
