AMR-AUTOMATED METER READING SYSTEM FOR LOSS REDUCTION DUE TO ERROR READING ISSUES

AMR System for electric utility use in automated meter reading

AMR system or the Automated Meter Reading System is a modern technology application of automatically collecting information, status report, and reading from utility meters like in the water, gas and energy. This automation process is made possible through the use of digital communication techniques such that it saves utility providers the expense of periodic trips to each physical location to read a meter.

Unlike the conventional way of reading meters where it is highly person dependent, AMR reduces if not eliminates human errors. Conventional meter reading rely so much on human judgment that a single incompetent meter reader can produce a significant loss to the utility. Since AMR uses the technology of communication, accessibility of meters in rural or highly urbanized area becomes less of an issue for the meter reader.

AMR contribution to systems loss reduction can be quiet excellent since the features of modern AMRs includes the ability to detect meter tamper events and outage occurrences. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption.

Much as the AMRs contribution to loss reduction, some drawbacks for this technology also exists. The benefits and the disadvantages of using AMR in electric utility are listed below;

The benefits of automated metering for an electric utility
• Accurate meter reading, no more estimates
• Improved billing
• Accurate profile classes and measurement classes, true costs applied
• Improved security and tamper detection for equipment
• Energy management through profile data graphs
• Less financial burden correcting mistakes
• Less accrued expenditure
• Transparency of “cost to read” metering
• Improved procurement power though more accurate data - “de-risking” price
• The benefits of smart metering for the customer.
• Improved billing and tacking of usage.

Disadvantages of automated metering for an electric utility
• Loss of privacy - details of use reveal information about user activities
• Greater potential for monitoring by other/unauthorized third parties
• Reduced reliability (more complicated meters, more potential for interference by third parties)
• Increased security risks from network or remote access
• Meter readers losing their jobs.

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").
