MIVII3000E00HI00 | GE Multilin | MIV2 voltage frequency relays

Description

The GE Multilin MIV2 and MIVII3000E00HI00 are voltage frequency relays used in electrical protection and monitoring applications, particularly in power plants and substations. These relays are designed to detect abnormal voltage and frequency conditions in electrical systems and can take actions such as tripping circuit breakers or sending alarms to prevent damage to equipment.

### Key Features:

1. **Voltage and Frequency Monitoring**: These relays monitor the system voltage and frequency, often providing settings for over-voltage, under-voltage, over-frequency, and under-frequency conditions.

2. **Programmable Settings**: Users can configure settings based on the specific operational requirements of their electrical systems.

3. **Communication Protocols**: Many models support various communication protocols like Modbus, DNP3, or IEC 61850, allowing integration with SCADA systems for improved monitoring and control.

4. **User Interface**: The relays typically have an LCD display for real-time data monitoring, and buttons for navigation through settings and parameters.

5. **Protection Functions**: In addition to voltage and frequency protection, some models may include additional protection functions such as phase failure detection or protection against loss of phase.

6. **Event Recording**: Many relays can log events and generate reports for analysis, which is essential for maintenance and troubleshooting.

### Application:

– **Power Generation**: Used in power plants to protect generators from abnormal voltage and frequency conditions.
– **Industrial**: Used in manufacturing and processing plants to ensure that equipment operates within safe voltage and frequency levels.
– **Utilities**: Implemented in substations for grid stability and protection.

### Installation and Maintenance:

When installing and maintaining these relay systems, it’s important to follow the manufacturer’s guidelines and perform regular tests to ensure their functionality. Keeping software and firmware up to date is also crucial for optimal performance.
