Watt-Hour Meter: Me kana? (Kuma Yadda Ake Gudanar)

A watt-hour meter shine wata shaida da yake iya bincika da kuma taka rawa kan karkashin kula da ke fitar da hanyar cikin kafuwar gaba zuwa lokacin. Idan an yi amfani da watt-hour meter, za mu iya samun ya dace cewa kula da ke fitar da hanyar cikin gida, IEE-Business, ko kuma wurin da ke fitar da hanyar. Kula masu asalin da suka sanin watt-hour meters a gidajen mafi girman su don tabbatar da kula da ke fitar da hanyar (don abubuwan bayanai).

An yi amfani da bayanan da aka bincika a har da kowane lokacin da aka ba bayanai. A halaye, zahiri na bayanai shine Kilowatt-hour (kWh). Wannan shine da take da yawan da ake fitar da hanyar da ake fitar da hanyar ta kila a lokacin da kuka.

Watt-Hour Meter yana nufin misali mai kula ko kula mai kula ko kula mai kula ko kula mai kula.

Duk da cewa watt-hour meter yana da kungiyoyi mai karamin kungiyar da kuma kungiyar da ake taka rawa. Kungiyar zai yi aiki da tsara da wata adadin da ya kai da kula da ke fitar da hanyar cikin kafuwar gaba da za a bincika.

Saukin da kungiyar yake yi ko karamin da ya kai da kula da ke fitar da hanyar cikin kafuwar gaba.

Saboda haka, kowane sauki da kungiyar yake yi shine daidai da wata adadin da ya kai da kula da ke fitar da hanyar cikin kafuwar gaba. An sanya kungiyar da kungiyar da ake taka rawa don taka rawa, kuma amfani da kungiyar da ake taka rawa don taka rawa.

Electromechanical Type Induction Meter

A non-magnetic and electrically conductive aluminum metal disc is made to revolve in a magnetic field in this type of meter. The rotation is made possible with the power passing through it. The rotation speed is proportional to the power flow through the meter.

Gear trains and counter mechanisms are incorporated to integrate this power. This meter works by counting the total number of revolutions, and it is relative to the usage of energy.

A series magnet is connected in series with the line, which comprises a coil of few turns with thick wire. A shunt magnet is connected in shunt with the supply and comprises a large number of turns with thin wire.

A braking magnet, a permanent magnet, is included for stopping the disc at the time of power failure and placing the disc in position. This is done by applying a force opposite to the rotation of the disc.

A flux is produced by the series magnet that is directly proportional to the current flow, and the shunt magnet corresponding produces another flux to the voltage. Because of the inductive nature, these two fluxes lag each other by 90o.

An eddy current is developed in the disc, which is the interface of the two fields. A force corresponding produces this current to the product of instantaneous current, voltage, and phase angle.

A break torque is developed on the disc by the braking magnet positioned over one side of the disc. The speed of the disc becomes constant when the following condition is achieved, Braking torque = Driving torque.

The gear arrangement linked with the shaft of the disc is implemented for recording the number of revolutions. This is for single-phase AC measurement. An additional number of coils can be implemented for different phase configurations.

Electronic Energy Meter

The major feature of the electronic meter other than power usage measurement is that it can display the energy usage on a LED or LCD. In some advanced meters, the readings can be transmitted to remote areas.

It can also record the amount of usable energy in on-peak hours and off-peak hours. In addition, this meter can record the parameters of supply and load like voltages, reactive power used, the instantaneous rate of usage demand, power factor, maximum demand, etc.

Smart Energy Meter

In this type of meter, communication in both directions (Utility to the customer and customer to the utility) is possible.

Customer to utility communication includes parameter values, consumption of energy, alarms, etc. The utility to consumer communication includes disconnect/reconnect instructions, automatic meter reading system, upgrading of the software of the meter, etc.

Modems are implemented in this meter to make communications easy. The communication system includes fiber cable, power line communication, wireless, telephone, etc.

Advantages of Different Types of Watt Hour Meter

The main three types of matt hour meters are:

1. Electromechanical Energy Meters

2. Electronic Energy Meters

3. Smart Energy Meter

The advantages of each of these types of watt-hour meters are listed below:
