Metal Oxide Varistor (MOV)

john March 24, 2011 23 Comments
Metal Oxide Varistor (MOV) Basics of Varistor A varistor/voltage dependent resistor (VDR) is a component which has a voltage – current characteristics that is very much similar to that of a diode. This component is used to protect electrical devices from high transient voltages. They are planted in the devices in such a manner that it will short itself when a high current is produced due to the high voltage. Thus the current dependent components in the device will...

Working of  SWR Meters This article focuses on the concept of Standing Wave Ratio, its measurement using SWR meters, directional swr meter, Voltage Standing wave ratio (vswr), Swr bridge circuit, applications and problems with an SWR meter. SWR Meter IMAGE SOURCE SWR meters are used to measure and denote the standing wave ratio in a communication line. That is, the meter will denote the exact mismatch between the transmission line and the load, thus helping to know the degree...

What is a Smart Antenna? Smart Antennas, also known as multiple antennas, adaptive array antennas, and so on is used to increase the efficiency in digital wireless communication systems. It works by taking the advantage of the diversity effect at the transceiver of the wireless system that is the source and the destination. The term diversity effect refers to the transmission and reception of multiple radio frequencies that are used to decrease the error during data communication and also...

Photonic Integrated Circuit Technology Photonic Integrated Circuit (also known as PIC), is a complex integrated circuit which incorporates a lot of optical devices to form a single photonic circuit. The main difference between a PIC and an Electronic IC is that PIC is analogous to an Electronic Integrated Circuit.  Many optical devices like optical amplifiers, multiplexers, de-multiplexers, optical lasers, attenuators and also detectors are integrated on to a Photonic Integrated Circuit. For a large-scale operation of such a device...

We have always thought of aeroplanes as the fastest mode of transportation. As it travels thousands of miles in an hour we do not mind the flight delays and also the risk in flying. There is no other alternative to planes that can travel such a great distance in minimum amount of time. Buses, cars, boats and even conventional trains seem to be too slow in comparison to planes. Now a new transportation mode has occurred that can clearly...
