Real-Time Power Transformer Monitoring With Dual SIM GPRS/4G for Status & Load Data

Hello all,
I am new to this forum and I have found it a very exciting and resourceful place.
A little background. I am an electrical engineer and I live and work in Nigeria. We have frequent outages in my country and sometimes it takes weeks before the utilities even know the status of a transformer. This results in people being in darkness for weeks and sometimes months. I want to help solve this problem
I am working on a project that involves real-time monitoring of power transformers. The parameters I am interested in are the operating status of the transformer (on/off), temperature of the transformer, the percentage loading of the transformer and sent the results real-time on-line. I am looking at sending it via SIM module(GPRS/EDGE/HSPDA/4G) and I want two sim modules for redundancy.
Can I get any help from this forum?
I look towards having a very engaging and intensive discussion here that will result to an actual physical device.
Thanks.

Kelechi,
A couple questions. First, are you employed by the power company? Or is this something that you want to sell to the power company? I ask this because otherwise you would not have sufficient access to the transformer for monitoring. Also I assume that it is the power company that would be fixing the problem once it has been determined where the fault is.

Are you assuming that the fault would be in the transformer or is that just a convenient location for the sensor?
Also, if you are working for or with the power company, please be aware that technology is improving to make location of faults easier. In some cases, faults can be located to within a short distance using equipment that can be installed at the substation.

I assume that your proposed device is intended to "call home" periodically or when it detects a problem. Have you thought about how to power the device? If the transformer is off, you will need a battery or some such to power the SIM module. And then it would be helpful to have it recharge when the transformer is on.
