PROJECT DESCRIPTION

The project is designed to develop an automatic tripping mechanism for the three phase supply system. The project output resets automatically after a brief interruption in the event temporary fault while it remains in tripped condition in case of permanent fault.

The electrical substation which supply the power to the consumers i.e. industries or domestic can have failures due to some faults which can be temporary or permanent. These faults lead to substantial damage to the power system equipment. In India it is common to observe the failures in supply system due to the faults that occur during the transmission or distribution.

The faults might be LG (Line to Ground), LL (Line to Line), 3L (Three lines) in the supply systems and these faults in three phase supply system can affect the power system. To overcome this problem a system is built, which can sense these faults and automatically disconnects the supply to avoid large scale damage to the control gears in the grid sub-stations.

This system is built using three single phase transformers which are wired in star input and star output, and 3 transformers are connected in delta connections, having input 220 volt and output at 12 volt. This concept low voltage testing of fault conditions is followed as it is not advisable to create on mains line. 555 timers are used for handling short duration and long duration fault conditions.

A set of switches are used to create the LL, LG and 3L fault in low voltage side, for activating the tripping mechanism. Short duration fault returns the supply to the load immediately called as temporary trip while long duration shall result in permanent trip.

The concept in the future can be extended to developing a mechanism to send message to the authorities via SMS by interfacing a GSM modem.

Q & A
Q:  What are the types of faults detect in this system?
A:  Three Line to Ground, three Line-to-Line and line to line are the types of faults detected in this system.
Q:  What is three phase fault analysis?
A:  The possible faults which occur in three phase are 3G, LL, 3L and analysis of these faults is called three phase fault analysis.
Q:  How does the system protect from these faults?
A:  It temporarily switches off the load when fault occurs for a very small time and goes to auto reset when fault is cleared or it permanently switches off the load when fault occurs for a longer duration of time.
Q:  Why 6 lamps are used?
A:  A series of two lamps are used to represent each phase. 2 lamps are connected in series to ensure safety.

We came to know about edgefx is through searching key words fault in three phase in google
By seeing the visibility of kit and credibility of edgefx
Support team helped me to purchase kit online with some additional discounts.
And the kit was delivered in right time with right components and the packing was excellent with beautiful box.
I will refer this site to our friends

I got to know to about edgefx through google. I was searching for electronic project in google then i got edgefx website.
I have decided to buy project from edgefx because there was cash on delivery that is why i purchased project from edgefx. I like most about edgefx kit is kit presentation.
Sales team has helped me in purchasing the project & the kit was delivered in time with right components.

Please make sure provide more and more advanced projects.
And also,I gave reference to my friend he has purchased the project.
