Load monitor and Breaker with Digital Display using Microcontroller

In recent days the application of micro controllers are increasing in electrical equipment protecting devices. Electrical systems are allowed to operate without any proper control system, so keeping this in mind we implemented a “Load monitor and Breaker with Digital Display using Microcontroller “  to protect the electrical systems from over currents.

The basic requirements of the protecting device are to monitor the changes in the current, voltage, frequency of the power system. For that we make use of micro controller in sensing the varying conditions and a protective relay is operated for protecting the network from un wanted over currents.

Project description:

The over current protection system uses an PIC micro controller, whenever the current in the main lines crosses a particular value the micro controller causes the circuit breaker to trip the circuit.

So firstly we need to monitor the load current so for that we use a current transformer whose primary is connected to the load terminals and its output terminals are converted into dc by using an rectifier and filter and it is converted in to digital pulses by the A/D converter, and then this digitalized pulses is fed to the micro controller, if this signal crosses the normal value it trips the circuit by passing signals to the relay circuit.

MicroController Based ECE Project Report on Smart Junction with Circuit Diagram

Introduction to MicroController Based ECE Project on Smart Junction:

With the economic growth of the global transportation acts as an instrumental and it happened since the start of the early civilization that is known to man. The major impact on the economy of the country happened due to the management of traffic. The discovery of Information and Communications Technology or ICT led to an increased production management and it happened in the era of the Industrial Revolution. This also results in enhancement of various new improvements that is introduction of cheap vehicles and construction of roads.

Over the last few years the enhancement in the population of the urban civilization and the ownership of the vehicle has also lead to an increase in the congestion of traffic on roads in the cities all across the globe especially in those areas that are populated densely, eg: India. Therefore it leads to the integration of the ICT with the infrastructure of transportation and vehicles that acts as a background for the Intelligent Transportation Systems. This system is here to deal with the congestion of traffic problem throughout the world and it will also make the system more efficient.

Artificial Intelligence is used by ITS for the automation purpose. ITS is also included in the technologies of vehicle detection as well as used for actuated control of signal of vehicles. The term actuated control means the signal dependencies on the split phase, duration time and phase sequence on the actuations of the vehicles that are registered at the detectors as other sensors meant for traffic as well as their response variance according to the present traffic demand.

Moreover, it is a kind of traffic responsive control system where the received signal inputs reflect the conditions of the present traffic conditions. It also uses this data to create the timing plan for crossing. This can create optimally as well as automatically. The vehicle detectors are the source for the receiving of these signals that are located at the crossings. It modifies the time plan from its default settings accordingly.
