Y wye and delta with a 3 phase supply you have two ways of connecting a traditional 2 wire load such as a light bulb or a server.

3 phase wye heater wiring. In both y and delta systems you can also connect it between any two phases x y y z or z x. In a y system you can connect it between any phase x y or z and neutral n. Three phase equations heater wiring diagrams open delta wye three phase heating circuits are most efﬁ cient when operated under balanced conditions. The wye configuration wiring diagram would look like.

Three phase supplies have properties that make them very desirable in electric power distribution systems. Three hot wires and one ground wire. How much will the power increase if the heater is wired in delta at 400v if it doesn t burn. Wye y connection also known as y connection is a three phase circuit in which all the three loads are connected at a single neutral point.

480v is the voltage between the 3 phases line to line. One neutral wire and one ground wire make for a total of five wires in 3 phase wye systems. V p phase voltage v l line voltage i p phase current i l line current r r1 r2 r3 resistance of each branch w wattage w delta 3 w wye w odelta w delta w owye w wye. If it is necessary to operate an unbalanced load the equations below can be used to calculate the circuit values for open three phase delta or wye circuits.

Unlike delta connection wye connected systems carry a fourth neutral conductor often grounded but sometimes left floating ungrounded wye system. The resistance of each winding card inside the heater is equal giving us a balanced load. The phase currents tend to cancel out one another summing to zero in the case of a linear balanced load. Ohm s law calculator 3 phase delta wye calculator.

Power transfer into a linear balanced load is constant which helps to. The terms used in the equations. User manuals specification sheets cad drawings and more. I wire it into star connection and apply 3 400v in order to have 230v phase voltage and the line current is around 18a.

Delta systems have four wires total. 1 3 of 3 000w is 1 000w. Therefore each phase will handle 1 3 of the load. The delta configuration has the three phases connected like a triangle.

For both wye and delta balanced loads wye and delta equivalent. I have a 12kw heater which has 3x 4kw 230v elements.
