Contest Brief

I'm looking for an experienced engineer to design a schematic diagram for a custom Micro-controller based Electronic Monitoring unit for a 33KV Aegis Ring main unit. The purpose of the monitoring unit is to detect faults and monitor power. The microcontroller platform I prefer is Arduino, and the preferred communication method is RS485. The Engineer should have experience and expertise in high-voltage technology, electronic circuit design, and microcontroller programming. Power monitoring should be limited to the current display and fault detection limited to only signal obtainable from the marshaling box of the RMU

I am still waiting for your answer before i can go back to the work. I still need to define my schematic first before turn it into PCB.

Hello Project owner, can you give us designer some feedback again our design?. Let us know if our design is on the right direction with your desire, so we can make another design based on your feed back.

Have a good day

Can you tell us more specific about how this machine works, from the source, sensor, controller, into monitoring. Well it seems there is no actuator action there, so its pure for monitoring purpose.

  Yes, it's purely for monitoring. No control

  the RMU has a marshaling box with terminations from the contacts of circuit breakers, current transformers the circuit should use these contacts for monitoring purposes
