Why monitor with a current sensor rather than check if power is on or not

Even when power is on, a device may or may not be running. If the equipment fails to turn on due to a fault, just knowing power is ON is not enough. With current based monitoring, the sensor trips only when the device is ON.

Can I use Proteus C5 to just monitor if my wall outlet loses power?

Yes you can but with a delay. It is possible to just monitor an outlet and be notified if there is power there or not. Please read the installation guide on how to use your Proteus C5 as a voltage monitor.
