A NEW APPROACH FOR DESIGN AND IMPLEMENTATION OF AMR IN SMART METER TECHNICAL PAPER

Authored by: Ms.Priya S.Kamble and Ms.Sonali T.Bodkhe

ABSTRACT
This paper elucidates a current measurement method for wide range residual current measurement. The paper discusses Automated Meter Reading, a technology used to automate the task of reading consumption records of subscribers. The problem is first defined in terms of Utilities, critical infrastructure needs, revenue protection and operational efficiencies. Various drivers as well as impediments within such scopes are the defined. Moreover, different technologies proposed and implemented are discussed. The paper concludes by capturing the conclusions obtained and suggestions for further improvements of such technologies for future applications.

INTRODUCTION
Although there are a variety of industry definitions, Automatic Meter Reading (AMR) generally is regarded as the reading of a utility meter by a means that does not require physical access or visual inspection of the meter. Utility companies across the world are experiencing the need for a major technological evolution in their day-to-day operational systems. A variety of factors are contributing to the drive to overhaul the entire system, tools and processes.

AMR system provides residents access to their consumption of water, gas and power meter remotely. At the same time the management department can analyze these real-time and accuracy meter data in order to make optimal resource distribution for future use. The key to successful AMR system depends on adopting which communication tools. Obviously the remote communication channel can be either GPRS/RF or fiber network based on the public service network. It can ensure remote transmission reliable and fluent without any maintenance fee.

CONCLUSIONS
Regarding low efficiency of traditional meters management, among them: high costs of gathering information, the need to be at the meter's installing location and low accuracy due to the man's role in data aggregation; it would be unavoidable to develop automated meter reading and management as a part of a larger automated network. The data was collected and analysed every 2 weeks. As the new AMR digital meters were installed in series with the conventional electromechanical ones their records were compared. All the 50 installed meters responded to the commands.

The least connecting distance was of a meter enclosed in a metal box behind two walls in an Indoor situation and the farthest connecting distance belonged to a meter installed outdoor behind a house wall. Time needed to get the last consumption records is 15 seconds which is 1/4 of the time needed to reach inside a house and read the meter.

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS How is electric motor frame size being specified? Motor frame dimensions have been standardized with a uniform frame size numbering system. This system was developed by NEMA and specific frame sizes have been assigned to standard motor ratings based on enclosure, horsepower and speed. The current standardized frames for integral horsepower induction motors ranges from 143T to 445T. These standards cover most motors in the range of one through two hundred horsepower. Typical example of where you can locate the frame is shown in Fig 1.2.D – Frame No. The numbers used to designate frame sizes have specific meanings based on the physical size of the motor. Some digits are related to the motor shaft height and the remaining digit or digits relate to the length of the motor. The rerate, or frame size reduction programs were brought about by advancements in motor technology relating mainly to higher temperature ratings of insulating mate...

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
