This invention relates in general to electrical circuits and relays therefor, and has more particular reference to detecting means for use in connection with signalling circuits and the like as employed in railway practice. In the case of signalling circuits and the like, it is desirable to......
The circuit uses an LDR (Light Dependent Resistor) as a light sensor, which, in simple terms, is a resistor whose value increases in darkness and decreases in the presence of light. Then it uses one transistor to detect the light, and another to drive the relay. When light falls on the...
Noun1.electrical relay- electrical device such that current flowing through it in one circuit can switch on and off a current in a second circuit relay circuit,electric circuit,electrical circuit- an electrical device that provides a path for electrical current to flow ...
An electrical circuit, controlled by an electromagnetic relay, comprising an electromagnetic relay having relay contacts for controlling current flow to a load in use, and a relay winding which, when energized, causes closure of said relay contacts. First manually operable switch means is provided fo...
Protective Relay Circuit The protective relay is used to detect abnormal conditions within the electrical circuits by measuring the different electrical quantities constantly under normal as well as fault conditions. The electrical quantities which may vary in fault conditions are; current, voltage, phase...
