to : ahlburutoeh diba separated cia ng certain phase, we are trying to study the three phase Ceiling type airconditioner, wherein hindi kasi gagana yung unit kung hindi proper yung pagkakabit. meaning to say:Line 1 sa Line 1 langLine 2 sa Line 2 angLine 3 sa Line 3 langhindi pwede pag interchange.
to : rdpzychooo nga magulo noh?? pero i like to have idea lang sa phase convertion, pero ang application ko ay 3 phase to single phase tlaga.sorry kung confusingto : ahlburutoeh diba separated cia ng certain phase, we are trying to study the three phase Ceiling type airconditioner, wherein hindi kasi gagana yung unit kung hindi proper yung pagkakabit. meaning to say:Line 1 sa Line 1 langLine 2 sa Line 2 angLine 3 sa Line 3 langhindi pwede pag interchange.to : alyaspagkakaalam ko nga out of phase siya nga with a certain degree.mayroon sigurong detector ang unit sa mga phase ng Voltage.. Tama enlighten naman us sa mga experts jan..hehehe
Hindi ko pa rin magets. Mathematically, you'll definitely get either more or less than 230V output if you use two 230V out of phase lines.Your answer just assumes you'll get 230V 60Hz single phase from using 2 230 live lines which are out of phase w/o any explanation.Ang pagkaka-intindi ko, in order to get lets say a single phase 230V from a three-phase system is by tapping only one line lets say L1, and feeding it to a 1:1 transformer. The output of the transformer is center-tapped and the center tap is earth grounded. This way, you get 2 115V on each line that adds up to a 230V output. I'm not an electrical engineer so I'm not sure of my understanding.
Reading this thread send my head spinning . Before this, connecting a single phase equipment to a three phase mains used to be so simple. Our workplace is serviced by 3 phase power source L1 L2 and L3. If I need to connect my single phase lap top computer to our 3 phase source, all I need to do is connect it to any pair, (i.e. L1-L2, L2-L3, or L3-L1). I need not worry about phasing or other stuff. I become choosy only when the equipment draws a significant amount of power, this is where load balancing, as alhburuto mentioned, becomes important.To sum it up, there is no such thing as power line "3 phase to single phase converter". Any pair (L1, L2, L3) will give you your single phase source.Yes, that's is correct. Pag mali ang kabit mo, reverse ang ikot ng motor compressor mo, di talaga gagana.
Ok I did a bit research on the net to satisfy my curiosity. Anyway there are 2 ways to power 1 phase systems from 3 phase power. One method, single phase to ground, which I generally know is tapping only one line of the 3 phase line and utilizing the neutral or ground.The other method is a phase to phase connection from 2 lines of the 3 phase lines. But generally, the output voltage is 173% of the single phase voltage.This was where I really got confused but technically, you are powering up a single phase device using two phase power. As for the single phase to 3 phase conversion, what I found out is it is mostly done through power conversion using a 3 phase power generator being run on a single phase motor.
yung atang airconditioner mo eh merong polarity protection relay na ginamit. yung design ng ikot ng motor eh di mo pwedeng baligtarin kasi merong chance siguro na me masira sa mechanical or sa flow ng fluid nya sa loob. yung mga ganung protection eh applicable sa mga 3 phase design. ang isang application pa nito eh yung sa mga 3 phase submersible pump. they use polarity protection relay. br
