Project Testing

After all the wiring and fitting completed, continuity test , provide supply , trib test done.. now it is the time to go to the final element, project test. Project will given up supply of a 240V and a load of 100Watts of bulb which is 6 bulbs overall total 600 watts. Once switch is turn on, all the bulbs is lights up.

Measuring total Amps in the circuit using clamp meter.

 

The output of the socket is 235V  as same as the input supply

Display read the meter well displaying the consumption power, value of kWh that had been used and the total value of the usage in Ringgit Malaysia

Hardware Development : Fitting and Wiring

After all the electrical stuff i had, i begin with  the box to place the circuit for Kwh meter.

then i place the distribution box next to the KwH box

 Wiring the connection for Main switch, Earth leakage circuit breaker, and Main circuit breaker. After done the wiring, do the continuity test again to check all the connection is good.

Drilling hole for fitting the bulb, switch and socket.

Fitting the bulb wire

Finalize the Hardware development .

Hardware Developement : contuinity test

To check the connectivity, i perform a continuity test, continuity test is  checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series) across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Devices that can be used to perform continuity tests include multimeters which measure current and specialized continuity testers which are cheaper, more basic devices, generally with a simple light bulb that lights up when current flows.

An important application is the continuity test of a bundle of wires so as to find the two ends belonging to a particular one of these wires; there will be a negligible resistance between the "right" ends, and only between the "right" ends.

When the continuity test done, i give them load to prove the continuity test  achieved. 240v supply connection applied (life,neutral and ground). i use test pen to complete the task. once i touch at the end poit of test pen the light is on which means the connection is good at no leakage voltage.

Software Development : Program the PIC

For software development i used MikroC, MikroElektronika C compiler for microchip PIC microcontrollers version : 8.0.0.0.

 

 I use basic C language for my project programming for PIC Microcontroller. after completed all of the program without any error( save file as .c), then compile all and proceed to burn HEX file to my PIC16F877A

1.  Import the HEX file
2. Reading the device and memory.

1.  verifying the device and memory
2. program was successful write into microcontroller.

The PIC Burner that i used to burn HEX file.
