3 basic types of energy meters energy meter or watt hour meter is classified in accordance with several factors such as: type of display like analog or digital electric meter.
There are different types of energy meters such as prepaid energy meters, induction type energy meters, analog or digital electric energy meters, three phase or single phase energy meters, electromechanical energy meters, microcontroller based wireless energy meters, smart energy meters and so on.
Watt hour meter or energy meter is an instrument which measures amount of electrical energy used by the consumers utilities install these instruments at every place like homes, industries, organizations to charge the electricity consumption by loads such as lights, fans and other appliances. Prepaid meter application form prepaid meter application form (national energy regulator of south africa) all our meters are correctly programmed as per the tariffs schedules of the various municipalities we do not tolerate unfair billing 3 service and penalty fees: i acknowledge that there is a per transaction service fee of either 10%.
Prepaid energy meter with gsm technology jubik, mareena john department of instrumentation and control engineering psg college of technology peelamedu, coimbatore, india abstract the usage of electricity automatically, if the bill is not paid the project also aims at proposing a system. The aim of the project is to automate the prepaid billing of energy meter and water meter in this project the front end is user friendly and the employees can work on this software with minimum knowledge of computers.
Interfacing energy meter with smart card technologythe system also the meter will be recharged in prepaid billing system, the electricity theft control using smart prepaid energy meter i international journal on applications in electrical and electronics engineering. Applications and advantages of the interfacing of prepaid energy meter with gsm modem by using this interfacing of prepaid energy meter with gsm system we can manage our loads through mobile phone, by checking the load status.
Rfid based prepaid energy meter basic idea: a scheme of electricity billing system called prepaid energy meter with tariff indicator can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings. This microcontroller based wireless energy meter consists of major components or blocks such as microcontroller, relays, loads, electricity consumption meter, lcd display, power supply circuit, gsm modem, db9 connector, max232, and relay driver.
Meter tariffs: prepaid electric adheres to the code of practice as laid out by nersa (national energy regulator of south africa) all our meters are correctly programmed as per the tariffs schedules of the various municipalities. Simple prepaid energy meter kit: a simplest type of prepaid energy meter consists of 2 eeproms interfaced to a microcontroller one eeprom contains the recharged balance amount the microcontroller reads this balance and stores it in the other eeprom along with the tariff. Practical prepaid energy meters: prepaid energy meter pe5120 it is a 3 in 1 dual source meter it also monitors water and gas consumption along with electrical consumption all the consumer has to do is to display the card in the front panel of the meter for a time of 3 seconds.
The electronic energy meter is also better protected against tampering than its mechanical predecessor, and units for prepaid operation (eg, card readers) and remote meter reading (eg, wireless, telephone line, or internet) can easily be included. To ensure that we pay all the money received via the prepaid meters / levy debit orders to the selected payment option as per the application 5 meter inspections: bypass notifications (only for clients who pay management fees) are sent out to owners if prepaid meter tampering is suspected.
