Edit: ok I see where I went wrong now. hmmmmm!

Hang on! I have a three phase heater 380v. In star connection, the line voltage is √3 times of phase voltage. Heater(s) 1 Phase Power Source Single Phase 120 VAC heater circuit where line voltage and current do not exceed thermostat rating. I wire it into Star connection and apply ~3, 400V in order to have 230V phase voltage and the line current is around 18A. Leverage Watlow's growing toolkit of calculators, equations, reference data and more to help design your thermal system. what i mean to say is that in star, by applying 3 phases, the star configuration gives you a neutral at the star point without the need for a neutral from the supply That wasnt my question; Fig.3: Phasor Diagram showing phase and line voltages.

I have a 12kW heater which has 3x 4kW 230V elements. 415 line voltage is 240 phase voltage in star. User manuals, specification sheets, CAD drawings and more. man At the moment I wire it in Star and I get 18A line current and 12kW at 400V, which is normal.If your going to end up with the same wattage and current, why change it? The term Y-Y applies since both the source and the load are Y-connected. This is the best way to learn. Ohm's Law Calculator 3-Phase Delta / Wye Calculator. Now they are wired in a star configuration. The connection depends on the rated voltage of the heater elements. It is shown as expression below isn't that the same as a motor wired in Y ?? I am with the man from niceic 16A & 2.5mm2

The fact that the three elements across three phases are connected in star forms a neutral point. each line current is lagging (30°+Ф) from the corresponding line voltage.It is seen from fig (3a) that each line is in series with individual phase winding, therefore, the value of line current is same as in Phase windings to which the line is connected.

Connect each component’s one terminal to another as shown in the above figure. I have a 12kW heater which has 3x 4kW 230V elements.Approx 12KW per element @ 30A each phase , thats nearly 36KW total power. Star Connection: In a star connection, phase voltage V ph = V L / (3) 1/2.Since the induced emf in the primary winding of an alternator is directly proportional to the number of turns, a star connected alternator will require less number of turns than …

In a three phase AC circuit, the total True or Active power is the sum of the three phase power. Originally the heater was connected in star configuration with P=6kw and In=9.11A. All about Electrical & Electronics Engineering & Technology. P=square root 3(1.732)*VL* Star Connection in a 3 Phase System In the Star Connection, the similar ends (either start or finish) of the three windings are connected to a common point called star or neutral point.The three-line conductors run from the remaining three free terminals called line conductors.

Star Connection Line and Phase Currents.

There are 6 x 2kw heating elements and i am stuggling to understand the operation. If the heater is made for 230 V phase-to-neutral three phase star connection and you supply it with 230 V with all three heater elements connected, you should be fine. .. but with no neutral at the star point. 2. Although the resistance of each element maybe be slightly different ( as are the windings on a three phase motor ) they will balance near enough. You need 9 kVA to supply it. Line voltage is the voltage between two phases in three phase circuit and phase voltage is the voltage between one phase to the neutral line. For a better experience, please enable JavaScript in your browser before proceeding.Welcome to ElectriciansForums.net - The American Electrical Advice ForumThere is a 12KW heater installed being controlled by a three phase thyristor control. Alan you are spoiling my wickedness Please consider supporting us by disabling your ad blocker. Therefore, it needs a low number of turns, hence saving in copper. We depends on ad revenue to keep creating quality content for you to learn and enjoy for free.Star Connection (Y): Three Phase Power, Voltage & Current Valuesthe starting ends or finishing ends (similar ends) of three coils are connected together to form the neutral point. Hi Guys I have a question. 3 phase immersion heater ke connection|YK Electrical - YouTube If your going to end up with the same wattage and current, why change it?

OrStar Connection is also called Three Phase 4 wires (3-Phase, 4-Wires) system.If a balance symmetrical load is connected across three phase voltage system in parallel, then the three currents will flow in neutral wire which quantities would be same, but they would be differ by 120° (out of phase), hence the vector sum of these three currents = 0. i.e.Star Connection (Y) Three Phase Power, Voltage & Current ValuesVoltage, Current and Power Values in Star Connection (Y)Now we will find the values of Line current, Line Voltage, Phase Current, Phase Voltages and Power in three phase Star AC system.Line Voltages and Phase Voltages in Star ConnectionLine Voltages and Phase Voltages in Star ConnectionLine voltages are 30° leading from the corresponding phase voltagesThe angle Ф between line currents and respective line voltages are (30°+Ф), i.e.
