Thanks Reply khairul Basar 02/18/2015 at 1:18 pm Please help me, I need a ATS wiring diagram by using timers and relay (three phase system) Thanks. 6) after specific time Timer Contact change it will give supply to DELTA contactor. star delta formation is correct and while tripping the currents taken minimum 715A in STAR and then shifted to delta it was tripping with overload.can u suggest me about star timing with formula and if it have to be run in closed transition please send me the power and control diagram with resistor calculation formula. Reply lemau says: 21/06/2012 at 10:01 PM you are welcome Very Happy Reply . The line current increases three times its value in star connection.During transition period of switchover the motor must be free running with little deceleration.

The motor might indeed rotate in the opposite direction but if the wires are not connected in the correct sequence as I stated above, then you most probably would have the gotten motors Phase Sequence wrong, which would result in the development of very high current peaks in the Open Transient Phase when the Star-Delta starter is switching between the Star and Delta modes. Only lasting a few milliseconds it causes voltage surges and spikes. Working Principle of Star-Delta Starter This is the reduced voltage starting method. The motor has a spinning rotor and behaves like a generator.Delta State: The Main and the Delta contactors are closed.

[I assumed the R connected to U1 correctly, and U2 then connects through the Delta Contactor KM2 to the B phase.] (reply) kalyanvvvvAug 09, 2013we are unable to download in pdf . This is known as transient current. Reply norman peoples 02/20/2015 at 11:33 am I once worked on a Large Burnt out 3 Phase Motor which was used for pumping sugar from the delivery Road Tanker Lorry into a Sugar Storage Tower Silo.
