Working of Static Relay The primary of C.T. is connected to transmission line and secondary is connected to some filter circuit. This filtered signal is given to rectifier where it is converted from AC into DC (Electronics equipments works on DC supply) The DC output is given to level detec...
The general kind of a relay makes use of electromagnet so as to perform opening and closing of contacts, whereas in the other types of approaches like in the solid-state type of relays they use semiconductor properties for controlling purposes without depending on the movable components. Relays t...
Arelaythat is used to execute safety functions within a machine or industry is known as a safety relay. This relay will work in the occurrence of a hazard and it reduces the risk to an acceptable range. Once an error occurs, then this relay will initiate a reliable & secure response, an...

Working Principle of Over Current Relay The core component of anovercurrent relayis a current coil. Under normal conditions, the coil’s magnetic effect is too weak to overcome the restraining force and move the relay’s element. However, if the current increases sufficiently, its magnetic effect...
The Layer 2 and Layer 3 hardware entries in the forwarding chip determine whether a switch can implement high-speed forwarding; however, the hardware entries in the forwarding chip are created based on the software entries maintained in the CPU. Therefore, the CPU is the core of a switch. CP...
The above image is a simplified solid state relay circuit. It consists of an input and output circuit. The input side is connected to the output circuit through an optocoupler, thus giving isolation between the input and output sides. When the optocoupler is activated by applying a voltage in...
