The true or real power is directly shown in a wattmeter. In three-phase systems, power can be measured using several methods. For temporary measurements, a single wattmeter can be used. However, for permanent measurements, a three-phase wattmeter having two elements is used which indicates both balanced and unbalanced loads. In this video, Ankit Goyal (Co-Founder at Kreatryx and AIR 1 in GATE 2014) explains how to measure three phase power using two wattmeter method. Also, GATE 2017 problem on the same has been solved.
/ syam kumar2.reasion due to low voltage in houses is, in our streetpoles we have generally 3 phase wires and 1 neutralwire.every house connected to 1 phase and neutral wire.ifmore number of houses connected by same phase then thoseare effected from this low voltage problem.so some houseswill have power and some houses effected from this lowvoltage. So if we connect equal distribution to all phasesthis effect is reduced. This connection will given by ourlinemen.3.flow of charge is currentand potential difference between any two points in aconductor is called voltage.voltage and current are combinational. Will a bulb glow if we connect it between the phase andearth instead of earthed neutral?How do you know when the battery is fully charged?,Can Anyone Answer anyone of these?Q1) why direct SOLUTION of Load Flow Studies in Not Possile?Q2)Why majority of Buses in power system are load busesQ3)Why one of the buses in Power system is taken as reference bus (slack or swing) Bus?Q4)Bus Admittance Matrix is a sparce (means it contains some zero elements ) matrix, give reasonwhat is power factor?how the 3phase induction motor is running in 2phase supplywith help of capacitor?Which. Type of motor used in.
Fan,What is inverse definite minimum time lag relay? Where is ituse?,what factors to needed while selecting a MCB and MCCBWhat is different between MCB & MCC & isolator switch,When a fourth resistor is connected in series with threeresistors, the total resistance,if 6 earth pit value is 1.5 ohm then what should be the number of earth pit to make the value.8 ohmmy question is Megger of cable insulation or swgr boardmeggerring some values in one day 50mohms,some other daychecking different values(20Mohms).this tell that some person tell that that values ok.how to identify the megger value is correct.pls tell me the answer. ::,.:: Banking Finance, Business Administration, Funding, Hotel Management, Human Resources, IT Management, Industrial Management, Infrastructure Management, Marketing Sales, Operations Management, Personnel Management, Supply Chain Management.:: Aeronautical, Automobile, Bio, Chemical, Civil, Electrical, Electronics Communications, Industrial, Instrumentation, Marine, Mechanical, Mechatronics, Metallurgy, Power Plant.:: USA Visa, UK Visa, Australia Visa, Canada Visa, Germany Visa, New Zealand Visa.
