Overview:
An advanced protection system was created for three-phase electric motors up to 440V and 1-600kW. The microcontroller-based design monitors and protects against electrical and mechanical issues like overcurrent, phase loss, and overheating. Key features include:
– Microchip PIC18F67K22 and Analog Devices ADE7758 chips for precise 3-phase power measurement.
– Real-time monitoring of current (True RMS), voltage, power, and faults with displays.
– Can detect overload, startup overtime, current imbalance, stalled rotor, undercurrent, short circuit, phase failure, phase reverse, undervoltage, and overvoltage.
– Smart trip zone settings and extensive fault logging capabilities.
– Iterative prototyping optimized performance, reliability, and cost-effectiveness.
– Simple user interface for setup and commissioning.
– Compact design for flexible installation.
Scope and Objectives:
- Design analog/digital hardware and embedded firmware
- Design PCB(Altium Designer)
- Embedded System Design
- Communication Protocols and Interfaces (I2C, SPI, RS485)
- Mechanical Design
- Create a low power, high efficiency, compact design
- Ensure compliance with standards and regulations (NEMA, IEC-62053-22)
- Debugging and Testing
