1. Overview - Automatic Meter Reading(AMR) System1.1 IntroductionAutomatic Meter Reading ( AMR) System via Power Line Carrier:

Power line carrier communications take place over the same lines that deliver electricity. This technique involves injecting a high frequency AC carrier onto the power line and modulating this carrier with data originating from the remote meter or central station.

Power line carrier techniques Nowadays become a successfully system by a few companies worldwide, In 1998 , Florida Electric Co., initiated 212,000 point PLC-based AMR system successfully with big saving and increasing the customer's services without any additional coast.

AMR System via PLC becomes a unique solution for utilities worldwide not only because it saving a lot, but also it is managing the bad debit, Theft, power control ,etc.. With no extra cost for communication Infrastructure by using the utility existing own network as communication media which making the PLC’s AMR more better than other AMR solution as IR,RF and GSM/PSTN or wireless.

2.0 DMC’s AMR System Features

AMR System uses the existing power lines to eliminate the need for additional communication cable

Remotely reading consumer’s power consumption in the distribution transformer, eliminating the need for on-site consumer readings by utility personnel

Real time monitor consumer’s power consumption

Storing, processing and print consumer’s data Freezing consumers’ power consumption Counting and analyzing power consumption for

the distribution transformer or the consumer Analyzing line wastage Providing tariff and billing Theft detection (according to analyzing power

consumption) Low cost for meter reading Very reliable and robust
