What is an Overcurrent Relay?

An. overcurrent. relay is an electrical protection device designed to cut off the. power supply. to a circuit, appliance, or machine in the event of an overload or failure. These devices typically consist of a manual. circuit breaker.

What is different between overcurrent relay and over load relay?
This a quote from Wikipedia: http://en.wikipediawiki/Relay. You have to scroll way down the page to see: Overcurrent relay. An Overcurrent Relay is a type of protective relay which operates when t ....etc

Abstract

This Project is about designing the controls of an Overcurrent relay using microcontroller. Relay is an electrical switch. Generally it operates on electromagnetic principle for switching action. Over current (OC) relay is a type of relay which performs its switching action based on an input curr ....etc

Solar energy is becoming increasingly attractive as we struggle with global climate change. However, while solar energy is free, non-polluting, and inexhaustible, solar panels are fixed. As such, they can not take advantage of maximum sunlight as weather conditions and seasons change. A solar panel receives most of the sunlight when it is perpendicular to the sun's rays, but the direction of sunlight changes regularly with changing seasons and time. Currently, most solar panels are fixed, ie the solar array has a fix ....etc

In an over current relay, there would be essentially a current coil. When normal current flows through this coil, the magnetic effect generated by the coil is not sufficient to move the moving element of the relay, as in this condition the restraining force is greater than deflecting force. But when the current through the coil increased, the magnetic effect increases, and after certain level of current, the deflecting force generated by the magnetic effect of the coil, crosses the restraining force, as a result, the moving element starts movin ....etc

c program for automatic car parking indicator using microcontroller 8051

This system will indicate empty and filled car parking slots at the entry. Now a days Car parking at shopping malls and markets is becoming a big issue and is causing to traffic jam. To avoid this problem we are designing this system to indicate empty slots and filled slots, so that a car driving person can directly take his car to that particular empty slot. we will indicate the slot state by LEDs and also in LCD screen. we will use IR sensors to sense the presence of c ....etc
