3 phase motor start delta connection explanation in hindi urdu duration. Ilinesquareroot3iphase which means that whatever supply current we have we need a wire cross section for 1 squareroot3 times line current only.
Wiring Diagram Star Delta 3 Phase
Delta connection for 3 phase motor. Therefore it needs a low number of turns hence saving in copper. In star connection the phase voltage is low as 13 of the line voltage. Take close notice of the polarity for each winding in the figure below. For three phase motors connection type is either star y or delta ac motor winding continuity test using a multimeter check the continuity of motor winding from phase to phase u to v v to w w to u each phase to phase must have a continuity if winding is ok. Line and phase currents are related to each other as. Delta connection in a 3 phase system in delta δ or mesh connection the finished terminal of one winding is connected to start terminal of the other phase and so on which gives a closed circuitthe three line conductors are run from the three junctions of the mesh called line conductors.
Delta or mesh connection δ system is also known as three phase three wire system 3 phase 3 wire and it is the most preferred system for ac power transmission while for distribution star connection is generally used. This video is 3 phase motor connection proper star and delta connection full step by step a to z crimping tools amazon httpsamznto2akjmjo youtube playlist video. In delta connection motor receives highest power output. For a given motor the fundamental difference between the star and delta connections is that the rated voltage for the star connection is 1731 x the rated voltage for the delta connection. That way a motor can be designed to run at either of two voltages 240 v delta or 415 v star for example. Another configuration is known as the delta for its geometric resemblance to the greek letter of the same name δ.
In delta connection the phase voltage is equal to the line voltage hence it needs more number of turns which increase the total cost. In delta connection phase sides are connected in a cyclical arrangement in order to make a closed loop as shown in figure 1. Star delta motor connection part 1 hindi urdu duration. If any particular phase fails the continuity test your motor is probably burnt. Whereas in delta connection line and phase voltage are. Electrical urdu tutorials 44553 views.
Three phase three wire δ connection has no common.
