Electrical Engineers Interview Guide. What is an Address in Communication Systems? It should be called as designator for the location of data in a storage device; allows the retrieval of data by reading the contents of a specific location. Also, the identity of a peripheral device. These (normally unique) allow individual devices on a single communications line to recognize and respond to messages directed at them. What do you mean by ARP? APR stands for address resolution protocol. A transmission control protocol/internet protocol (TCP/IP) process that maps an ID address to an Ethernet address; required by TCP/IP for use with Ethernet.
What is the role of ARQ in data transmission? Automatic request for transmission. What is ASCII standard ? American Standard Code for Information Interchange. What do you mean by asynchronous Communications? What is bandwidth in communication? The range of frequencies available, expressed as the difference between the highest and lowest frequencies, in hertz (cycles per second, abbreviated Hz).

ICE Society :: Instrumentation and Control Society. Circuit Breakers : Theory Page 1. All electric circuits needs a switching device and also a protective device. Switchgear is the general term covering a wide range of equipment connected with switching and protection.
A circuit breaker is a switching and circuit interrupting device. A circuit breaker serves two purposes: (i) Switching on and off during normal operation for maintenance etc. (ii) Switching during abnormal conditions- short circuits, earthing etc. to protect the associated equipment. In short, a circuit breaker is a sort of automatic switch which can interrupt the fault currents.
(i) Arc extinction system (ii) Relay for operation Arc Extinction : Whenever a circuit carrying current is interrupted by a circuit breaker an arc is inevitably formed between the contacts which prolongs the current interrupting process for a duration ranging from 10 to 100 or more milliseconds. The ionization process is accompanied by the emission of light and heat. Methods of arc extinction : Two methods commonly used are: 1. 2. 3. 4. Untitled. As cited on fromdev.com, here are eight most popular PHP IDEs - 1. Codelobster PHP Edition – The CodeLobster PHP maintains Windows platform. The Plug-ins are not free but the registration is absolutely free.

How AM and FM Works. Building a wireless energy transfer circuit step-by-step. Five Lightweight Linux Distros For Your Old PC. Puppy Linux This is the smallest Linux distro at just 132MB download. The distro loads itself entirely into RAM on bootup, so is incredibly quick and responsive. However, if one wishes to use a modern browser, one would need 256MB. This is a truly portable distro, allowing the user to save documents to the same USB drive it boots from. Peppermint OS Two The OS is based on Lubuntu, which in turn was based on Ubuntu. Macpup 528 This is a great choice for those who think that the Puppy Linux is too retro-ugly. Crunchbang Linux 10 Based on the Debian project, this distro uses the Openbox window manager.

A bachelor’s degree in electronics, electrical or computer science and, of course, a good understanding of the topic is all it takes to launch your career in FPGA Jalaja Ramanunni The job situation in field-programmable gate arrays (FPGAs) has seen an uptrend in the last few years due to increase in their use in different areas.
FPGAs were first introduced into the market about 25 years ago and back then, it was a very simple technology. “Earlier, people could easily create any logic on FPGAs, but now these are more technical in nature,” says Sanjay Churiwala, director, ADVS, Xilinx India. “FPGAs today come with high-speed interfaces and serial communication protocols. Today, design development at the block level is mostly independent of target implementation. “We expect India to grow as a market for engineers equipped with FPGA skillset.

The wireless security hub by Maven Systems is a security solution for homes and small offices that can detect and report fire, gas leakage or intrusion.
The alerts are almost real-time (within minutes of the detection), and the information reaches the owner, neighbours and security guards in the housing colony or workplace almost instantaneously. FlashbackSuhas Jain, project manager, Maven Systems, says, “Safety and security is a must-have in today’s world.
However, most of today’s systems require advanced planning to install such systems. This means existing houses need chiseling of walls for laying additional cables. Owners are looking for a solution which doesn’t require any new wiring, yet takes maximum advantage of their telecom and Internet connectivity.” System componentsThe wireless security hub houses a host of components to communicate intrusions and other security parameters to the respective devices: RF adaptor.

Temperature is the most often measured environmental quantity and many biological, chemical, physical, mechanical and electronic systems are affected by temperature. Some processes work well only within a narrow range of temperatures. So proper care must be taken to monitor and protect the system.
When temperature limits are exceeded, electronic components and ciruits may be damaged by exposure to high temperatures. Temperature sensing helps to enhance circuit stability. By sensing the temperature inside the equipment, high temperature levels can be detected and actions can be taken to reduce system temperature, or even shut the system down to avert disasters. Several temperature sensing techniques are used currently. ThermocouplesA thermocouple consists of two dissimilar metals joined together at one end, to produce a small unique voltage at a given temperature. Thermocouples are available in different combinations of metals or calibrations. The first is operating temperature range. Robotics.

Basic selection of MV public distribution networks. Voltages induced by MV networks in telecommunication cabled network circuits Medium voltage – MV – public distribution networks are constructed on the basis of two fundamental parameters which influence the majority of their components as well as their operation. These parameters are the neutral management mode and the operating voltage. Selection of these parameters has a very high impact on the whole network, and it is very difficult, if not impossible or economically unrealistic, to alter them subsequently.
It is therefore essential to fully understand the influence of these decisions on other network parameters such as the protection system, safety, fault management, etc. This document details the limits imposed by these decisions and considers the various existing solutions, pointing out their advantages and disadvantages.

Basics of Circuit Breakers. Basics of Circuit Breakers - SIEMENS Need for Circuit Protection / Current and Temperature Current flow in a conductor always generates heat. The greater the current flow, the hotter the conductor. Excess heat is damaging to electrical components and conductor insulation. For that reason, conductors have a rated continuous current carrying capacity or ampacity. Overcurrent protection devices, such as circuit breakers, are used to protect conductors from excessive current flow.
These protective devices are designed to keep the flow of current in a circuit at a safe level to prevent the circuit conductors from overheating. Excessive current is referred to as overcurrent. Overloads An overload occurs when too many devices are operated on a single circuit, or a piece of electrical equipment is made to work harder than it is designed for. For example, a motor rated for 1 0 amps may draw 20, 30, or more amps in an overload condition. Because the motor is drawing more current, it heats up. Production Systems and Control. IEEE.

Understanding Vector Group of Transformer (part 1) Understanding Vector Group of Transformer Introduction Three phase transformer consists of three sets of primary windings, one for each phase, and three sets of secondary windings wound on the same iron core. Separate single-phase transformers can be used and externally interconnected to yield the same results as a 3-phase unit. The primary windings are connected in one of several ways. The two most common configurations are the delta, in which the polarity end of one winding is connected to the non-polarity end of the next, and the star, in which all three non-polarities (or polarity) ends are connected together.
The secondary windings are connected similarly. This means that a 3-phase transformer can have its primary and secondary windings connected the same (delta-delta or star-star), or differently (delta-star or star-delta). Basic Idea of Winding An ac voltage applied to a coil will induce a voltage in a second coil where the two are linked by a magnetic path. Polarity Example – Dyn11.
