Analouge Meter

For some reason, i have to change the from digital meter to analogue meter due the high cost of digital meter. It is about RM 1+++. Actually there is no different with digital meter as long as i can get the same accurate output at the display.

General Description

• The Single-phase Kilowatt-hour Meter Type DD28 is an instrument of induction type, used for measuring the singlephase.A.C. energy of rated frequency 50Hz.The instrument is novel design, attractive appearance, compact and sturdy construction. The instrument features high.accuracy, over wide load range and a long service life. All the components of this meter are of selected material and the metal ones electroplated or finished with baking enamel. The casing and terminal block with gasket are properly treated against mould, moisture and dust.

Technical Characteristics

a. Sensitivity
When the meter is running with 0.5% rated current at rated voltage and frequency and unity power factor, the rotor willrotate ceaselessly.

b. Running with No Loading
With no current in the current circuit, the rotor will not make a complete revolution at any voltage between 80% and110% of rated voltage.

c. Power Consumption
With no current in the current circuit, the power consumption of the voltage circuit is within 1.5W at rated voltage and frequency.With rated current circuit, the power consumption of the current circuit is within 2VA at rated frequency.

d. Insulation Test
With the specified ambient temperature and relative humidity below 85%, the insulation between the casing and all the circuits can withstand a test of 2kV, 50Hz for 1 min.

Estimated Project Cost

Table shown the estimated cost for completing the project. Any additional cost may accure during the progress to finalize the device.

Overall total is RM 574.00

Expected result

1. When the device complete in terms of the system design, we can get an accurate amount of usage in a display meter.
2. From the usage amount, the device is set to the same rate per block as TNB rates of electricity.
3. The value of the electricity usage will display in Ringgit Malaysia.
4. This device can be implement in a future development of nation electricity field. Reliability estimation was found to be the one of the best method to know the usage of electricity, a monitor that gives a real time feedback on how we consuming in our usage.

flow chart

this is the flow chart of my project. i begin with the literature review on hardware first then go to the literature review on software. Next i decide on design system. If got any problem, i get back study on design system if there is no problem with that, i start with programming the PIC then hardware building on TNB meter reading. Once done lab test will conduct to get the result.Result will show the next step.If every things good proceed with the circuit combination and project testing until the project achieved.

Problem statement

When static meter system has been designed and installed, it is usually necessary to measure and confirm the connection to the display of currency conversion.

• The problem is how to make a connection within these two devices to get the same output in kilowatt/hour in static meter same goes to the display.
• In some unfortunate instances, sometimes it failed to measure the accurate value of each driven test. There are a few reasons for this to happen, among others are: human errors, connection error, and programming error or device failure factor. For this reason it is important to develop methods to estimated reliability of such system, to ensure it will perform satisfactorily when needed the most.

Objective of this project

This research study intends to plug the research gap and will demonstrate the development of the techniques to estimate the new way of knowing the electricity usage in real time.

• a) The development of new measuring methods by considering the connection output from static meter.

• b) The application of the proposed new methods to determine the appropriate currency conversion types for particular applications from the output.

• c) The application of the proposed reliability new methods to identify the best design configuration in terms of the system’s reliability and availability.

• d) Validating the system’s reliability parameters obtained from the proposed new methods by considering the results in Ringgit Malaysia currency.
