Electromechanical meters create lots of problems ranging from technical, social and management problems. Moving parts within the watt-hour meter are subject to wear and tear, additionally its magnetic component operation depends on it temperature. Over time these wear and tear builds up to cause errors within the meters.
These meters are read manually for billing and this where management problems begin, since they have little control over this. To begin with the meter may not always be accessible for reading for various reasons, consumers not home, vicious dogs, or consumers themselves preventing meter readers access to the meter. Whenever this happens it leads to an estimated bill where sometimes the costumers gains or the GPL gains, a conflict more than often is created because of this. Some other problems are human error in reading, irregular bills, bills being misplaced etc. The most problematic area is the ease of tampering. These meters can be bypassed easily. The mode of disconnection also presents opportunities for corrupt employees to be involved in illegal connection.
It’s hard to think of any advantages that the watt-meter presents to a power company except that over time it has helped in identifying its own weaknesses.
Electronic meters
A Watt hour meter is becoming a thing of the pass with the more advance electronic meter replacing it because of the many advantages it presents. For one, the electronic meter is more accurate in that the errors are smaller below 0.1%. Not only that, it can store data which enables it to support various Automated reading and smart grid technologies.
Principle of operation
The electronic energy is based on Digital Micro Technology (DMT) and uses no moving parts. The accurate func...

...s report. The CIU is a compact, user friendly keypad and display and can be installed anywhere in the consumer’s home where there is an electrical outlet. As for installation the meter itself is mounted and secured on the pole top. This will allow the meter to be more accessible to the power company this way.
A key feature of this meter is that it can use standard household wiring to communicate, reducing the need for additional communication wires. This reduces the cost of installation.
The CIU operated directly from the mains voltage when there is sufficient credit in the meter. When credit expires the power is disconnected. To compensate for this two standard AA Alkaline battery is fitted on the CIU to reenter a new credit voucher in case that the credit expires. A low credit warning tone is also featured on the CIU which can be silenced with the press of a key.
All of the sources of current to the equipment should be isolated and signs need to be fixed to ensure that the nature of the equipment is known
For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...
Do you feel like having power is easy as turning on a light switch to to plugging an appliance into the wall maybe you do but after reading this your opinion might change.This research paper will discuss the idea of barehanding and how to work on energized power lines.
Greater shift towards smart grids, smart metering and building automation: Smart grids helps in intelligent distribution resulting in minimal losses whereas measurement and reporting of consumption in real time is achieved by smart meters.
Room occupancy Monitoring: This will monitor that there is how many people in the room so that the amount of air and humidity can be controlled also if there is no one in the room then the lights will be automatically switched off.
The module AC/DC is directly related to the career path of the electrical linemen. In the module i learned about two types of electrical current, alternating (AC), and direct current (DC). In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in (AC) circuits also periodically reverses because the current changes direction. Electrical lineman work on power lines and other thing that have (AC) or (DC) current depending on what they are working on. Lineman work on electrically energized (live) and de-energized (dead) power line. They may perform a number of tasks associated with power lines, including installation or replacement of distribution equipment such as capacitor banks, distribution transformers on poles, insulators and fuses.
In recent years there has been a growing trend involving the use of closed circuit
Also, it requires a fast and secure communication to monitor real-time connection status to act as Energy Manager. [SANCHEZ]
In fabrication micro-sensors and devices micro-electro-mechanical systems (MEMS) provides significant opportunities, which are borrowed it fabrication abilities from semiconductor technology.
Since early 2003 the Electrical Inspectorate has been working to raise public awareness of Residual Current Devices (RCDs), with the aim of eventually enforcing the use of these devices as recommended by the standard adopted by the St. Lucia Bureau of Standards for wiring of buildings SLNS/BS 7671: 2001- Requirements for Electrical Installations ¡V IEE Wiring Regulations ¡V Sixteenth Edition. These Regulations though only recently adopted by the Bureau of Standards is the Regulations referred to by the St. Lucia Electricity regulations of 1973 as the standard of wiring of buildings. For a very long time the cost of these devices had proven prohibitive for the enforcement of the requirement. However, it is now believed that safety concerns as it relates to electrical hazards such as fire and electrocution far outweigh the cost of these devices
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
Older homes and historic homes are more likely to have outdated wiring. Wiring and its insulation can fray and crack from age, heat, corrosion, or bending. They can also be damaged during construction and remodeling. Damaged wires can cause a fire, and require prompt service from a licensed electrician. A Tioga Contractor electrician in Southlake can provide the electrical services you need to ensure the safety of your family, and
As an engineering student, design, develop and test electrical equipments is the major purpose of all time. In other words, electrical engineer is concerned with using electricity to transmit electric power. In electrical engineering, there are extensive subfields such as power engineering, control system and signal processing. It is also worth to point out the difference between electrical engineering and electronic engineering. According to the research, electronic engineering is a major that deal with the electronic system such as computers and radar, to be more specific, electronic engineers are concerned with using electricity to process information.
In power stations electricians need to use a variety of device to ensure that they are doing the job correctly. The four essential things an electrician needs to consider is earth wire, double insulation, fuse box and a residual circuit breaker. These four things are essential because they help to increase the health and safety of workers.
Energy storage battery is one of the mostly used electrical energy storage technology. Recent technology advances coupled with the flexibility, portability and scalability of energy storage battery, in addition to the declining costs and improved performance, have favored its usage for a variety of applications. Energy storage battery capacity varies from a single unit of a few watts to modular configurations of up to several megawatts.
