Reactive Power and Power Factor



Ptotal
Qtotal (5)
For example:
1. P1 = -80 Watts P2 = 127 Watts
| Ptotal | = 47.0 Watts
| Qtotal | = 358.5 VARS
| θ | = tan –1
                                    | 47 |
| 358.5 | = 82.53o
      2. P1 = 127 Watts P2 = -80 Watts
| Ptotal | = 47.0 Watts
| Qtotal | = 207.0 VARS
| θ | = tan –1

| 47 |
| 207 | = 77.21o

“Pattern”- making, allowances and its types

“Pattern”- making, allowances and its types: Pattern: A pattern may be defined as a model of desired casting which when moulded in sand forms an impression called mould. The mould when filled with the molten metal forms casting after solidification of the poured metal. The quality and accuracy of casting depends upon the pattern making. The pattern may be made of wood, metal(cast iron, brass, aluminium and alloy steel.), plaster, plastics and wax. Pattern Allowances: A pattern is always made larger than the required size of the casting considering the various allowances. These are the allowances which are usually provided in a pattern. 1: shrinkage or contraction allowance: The various metals used for casting contract after solidification in the mould. Since the contraction is different for different materials, therefore it will also differ with the form or type of metal. 2: Draft allowance It is a taper which is given to all the vertical walls of the pattern for eas

IBOC Technology

             FM In-Band On-Channel (IBOC) Digital Radio Abstract The In-Band On-Channel (IBOC) solution to replace stereo quality FM transmission with CD quality sound using the same FM channel has had further advances in the USA. The National Radio Systems Committee (NRSC) has evaluated the ubiquity Digital Corporations FM IBOC System to determine the compatibility of IBOC operation with analog reception of existing FM stations. This paper outlines the basic technical fundamentals of IBOC, the current status of the technology and the possible impact of IBOC on the Australian broadcasting environment. What is IBOC IBOC (In-Band On-Channel)1 digital radio technology, also referred to internationally as Digital System C, facilitates the introduction of Digital Sound Broadcasting (DSB) by allowing existing FM stations to broadcast the same programming in analog and digital without the need for new spectrum allocations for the digital signal. IBOC is capable of transmitting au

K-Map (Karnaugh Map) In many digital circuits and practical problems we need to find expression with minimum variables. We can minimize Boolean expressions of 3, 4 variables very easily using K-map without using any Boolean algebra theorems. K-map can take two forms Sum of Product (SOP) and Product of Sum (POS) according to the need of problem. K-map is table like representation but it gives more information than TRUTH TABLE. We fill grid of K-map with 0’s and 1’s then solve it by making groups. Steps to solve expression using K-map- Select K-map according to the number of variables. Identify minterms or maxterms as given in problem. For SOP put 1’s in blocks of K-map respective to the minterms (0’s elsewhere). For POS put 0’s in blocks of K-map respective to the maxterms(1’s elsewhere). Make rectangular groups containing total terms in power of two like 2,4,8 ..(except 1) and try to cover as many elements as you can in one group. From the groups made in step 5 find the p
