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. 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? Communications in which characters can be transmitted at an arbitrary, unsynchronized time, and where the time intervals between transmitted characters may be of varying lengths.Communication is controlled by start and stop bits at the beginning and end of each character. What is bandwidth in communication? What does band pass filter do?
Energy Business Review Chapter 13: Power Purchase Agreement | Windustry A power purchase agreement (PPA) is a contract to buy the electricity generated by a power plant. These agreements are a critical part of planning a successful wind project because they secure a long-term stream of revenue for the project through the sale of the electricity generated by the project. Securing a good PPA is often one of the most challenging elements of wind project development. This section covers the basics of a power purchase agreement and things to consider as you negotiate with a power purchaser. A Power Purchase Agreement (“PPA”) is a long-term agreement between the seller of wind energy and the purchaser. Back to Top Length of the Agreement PPAs are long-term agreements. The PPA may also provide the purchaser an opportunity to extend the PPA to include a renewal term beyond the initial stated term of 15 to 25 years, such as an additional 5 years. Commissioning Process These conditions for commercial operation may require the seller to demonstrate to the purchaser that:

What is Coal? | Types of Coal | World Coal Association Coal formation began during the Carboniferous Period - known as the first coal age - which spanned 360 million to 290 million years ago. Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store solar energy through a process known as photosynthesis. When plants die, this energy is usually released as the plants decay. Coal formation began during the Carboniferous Period - known as the first coal age - which spanned 360 million to 290 million years ago. Coalification The quality of each coal deposit is determined by: varying types of vegetation from which the coal originateddepths of burialtemperatures and pressures at those depthslength of time the coal has been forming in the deposit Types of Coal Different types of coal also have different uses, as shown in the diagram above.
Electrical engineering interview questions and answers 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.
