Product 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.

Get 100% Assured Successful Results

A simple and effective plan that assures you the best scores, a plan that gives you time to read, learn, practically experience the whole workings of your project and create a successful unit you can proudly showcase. And the best part is this… even if your own project unit malfunctions... you will still have a ready-made project unit for yourself, just in case there is a last minute issue that you or your teammates could not solve. Confused? Well let me explain.

Plan A: Create A Successful Project Model By Yourself

Plan B: Have A Expertly-Made & Quality-Tested Replica Of Your Project For Assured Results

So here’s how it works.

In my engineering days, we used to struggle replicating a PCB model from our text books with real tools. We had a tough time with the circuits and most of the time - they used to fail. So I wanted to solve this problem not just for myself but for all my fellow students like you. Young, energetic and knowledgeable youth who really want to learn but still cannot afford to fail with the project because it matters and the colleges rarely help us out productively.

So I want to give you a beautiful DIY model of the project that also includes:

  1. A Complete set of tools, circuit diagrams, tested PCD, zero board, audiovisuals and everything else you will need to execute your project to perfection.
  2. A ready-made unit of the project itself, so that you can actually see, test and learn in real-time and if by any chance you could not complete the unit by yourself - can submit this unit for an assured first-class score.

Sounds like a dream? Well, yes it is and here’s how you can benefit from this project not just in your final year but also help you with your interviews and in the future too.

"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"

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.

Q:  Can one replace the lamp by an induction motor?

A:  Yes, the lamp can be replaced by an induction motor.

Q:  What would be rating of the motor?

A:  A 3 phase, ¼ HP motor should be used.

Q:  What is the three phase induction motor rating to be used?

A:  Three phase induction motor can be used, but limited up to 1 HP only as it uses a relay of 6A contact rating only. For higher HP just use a contactor of appropriate rating. The 230 AC coil of the contactor is powered in series from one of the contacts of the relay.

Q:  Can we use this project in commercial purposes?

A:  The features desired by real use can be done but cost would be high enough beyond the affordability of an average student expenditure point of view. Therefore the relay used in the project is totally different from the actual relay used in the control room.

Q:  Can we test this project using single phase supply?

A:  Yes. Connect primary of all the transformers of 1 to 6 to single phase supply.

Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?

A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.
