PROJECT DESCRIPTION

The project is designed to check the sequence of the 3 phase supply. It is very important to know the phase sequence particularly for 3 phase motors. For example, if the 3 phase motor is used for pumping action, any phase reversal accidentally resulting in wrong sequence could force the motor run in the wrong direction. This could result in dry run of the motor to develop permanent fault.

In this project direct 3-phase AC supply 50Hz is fed through voltage drop arrangement duly stabilized by zennor diodes to a logic circuit comprising of NAND gates and OR gates to detect the proper sequence of RYB by series of pulses of fixed duration.

In the event of changing the sequence from RYB to say YBR, the combination of NAND and OR gates develops an output with a missing pulse during the fixed time duration. This pulse is used in triggering an input signal to a 8051 series microcontroller through a timer to drive LEDs placed in a circle. In proper sequence the LEDs run  clockwise having received no triggering.  

While the sequence is not there the triggering is  done which is indicated by LEDs running clockwise for some time and then anti clockwise for the next and so it continues. DC requirement of the circuit is powered from a step down transformer along with a bridge rectifier ,regulators and filter capacitor.

Further this project can be enhanced by providing a relay to circuit to cutoff the supply to the load.

Q & A
Q:  What is phase sequence checker?
A:  It checks the order of phase R-Y-B
Q:  Why it is needed?
A:  It is needed to run motor in desired direction
Q:  Where is it applicable?
A:  It is applicable in industries for ensuring right direction of induction motor rotation.
Q:  What happens when any phase is out of sequence?
A:  It will cause the induction motor to rotate in reverse direction, and incase it connected to a pump, this will lead to reverse pumping.

I got to know about edgefx through google. I was searching my project title in google then i got to know about edgefx..
I have decided to buy project from edgefx because i found my project which is similar to edgefx project that is why i have purchased project from edgefx. I like the kit presentation.
the kit was delivered in time with right components.
i have a called to a person the number which is given in the website.
i want to give reference to my juniors.

I searched for the words like Phase Sequence Checker for Three Phase Supply and find in Edgefx in Google.
I found this project Title so decided to buy that project from Edgefx.
I purchase through online

I come to know about Edgefx through Internet.
I decided to buy a project from Edgefx because by seeing the website it is really attractive and requirement of my project is available here.
I purchased through online.
