In this assignment‚ a typical power network is constructed and Load Flow Analysis is performed. Short circuit levels and Fault current levels are monitored and compared with those obtained from analytical calculations

provides exponential growth until it reaches to its last limits. When this happens the new paradigm replaces the old one and we call this a paradigm shift. In computation history of exponential growth‚ this has already happened four times. Integrated circuit which we called Moore’s Law is the fifth Paradigm. The first paradigm was Electromagnetic calculators‚ flowed by second Relay-based computers‚ then third Vacuum tubes and fourth Discrete transistors.[4] Every paradigm

The astable multivibrator generates a square wave‚ the period of which is determined by the circuit external to IC 555. The astable multivibrator does not require any external trigger to change the state of the output. Hence the name free running oscillator

an integrated circuit (also known as IC‚ microcircuit‚ microchip‚ silicon chip‚ or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices‚ as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics. A hybrid integrated circuit is a miniaturized electronic circuit constructed of individual

Wire Ampacity and Size 1. Maximum loading for any branch circuit is 80% of rating of circuit for ampacity of wire for any load. NEC 220-2‚ use NEC 310-16 for ampacity. This applies to not more than 3 phase conductors in 1 conduit. Warning Voltage Drop NEC 310-16 wire ampacity tables do not take into account voltage drop‚ only thermal limit. Overhead triplex‚ use 310-16 for wire ampacity. Rule of Thumb If circuit is loaded up to ampacity and distance to load is around 100 feet
