Test Condition Condition 1 Test without load : PLC signal was sent from the transmitter module through the power lines (up to 1,510 meters) to the receiver module without added noise or load. Condition 2 Test with load : PLC signal was sent from the transmitter module through the power lines (up to 1,510 meters) to the receiver module with added load and noise from computer, motor and UPS (Uninterruptable power supply). 35
Test Condition Condition 3 Test with load and transformer crossing : PLC signal was sent from the transmitter module through the power lines (up to 1,510 meters) and across the transformer to the receiver module with added load and noise from computer, motor and UPS 36
Field testing The communication was established between the master PLC module (DCU) and slave PLC module (meter) for both LV to LV communication and MV to LV communication. 37
