Well, as far as I know, there is no 'gas' A/C. The A/C will be electric, regardless of the type of heat used. Whether electric heat or gas heat would be more economical is really dependent on your electric and gas utility rates and the efficiency of the appliances involved.
noise filters are used in electronics and electric curcuts to reduce the the noise level which the electric switching generats sometimes the are single phase and there are three phase also the most used noise filters are ssr emc filters
Yes, there is a difference between single phase and three phase circuits.
No...that's too much voltage, and 277v is normally three-phase power.
Three phase or two phase? Three phase requires three large wires for the current needed
short circuite means phase to phase,three phase short, phase to earth, three phase to earth, this is all short circuite
Three phase is used mostly with electric motors! Greater power with less current and more economical also. Motor runs cooler and starts quickly with improved starting torque.
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.
No, you cannot get a three phase supply directly from a single phase supply. Nowadays electronic inverter units can be bought that will do the job. For very low power loads the cost of such invertors is quite reasonable but for high power loads they are very expensive. For high-power industrial uses the most economical solution is to have a 3-phase service installed by the local electric power utility company.
Two-phase supplies, in which the phase voltages are displaced from each other by 90 degrees, are less economical than three-phase systems.
It is probably a three phase 50 Hz motor.
yes but voltage will be out a little.This ok for something like a heater which wont care.But for an electric motor starting and overheating maybe a problem.In the US this would be 220v single phase and 208 volts 3 phase.
This inverter is the cheapest and always available from famous vendors like ROCKWELL ,ABB, SIEMENS ,SCHNEIDER ELECTRIC....etc .
All high-voltage distribution systems are three-phase. Single-phase 'spurs' off the main line, supplying, for example, farm houses, are simply two lines of a three-phase system.
For a given load, a three-phase system uses less volume of copper (therefore is more economical) than a corresponding single-phase system, while supplying approximately-constant power. From the users' point of view, three-phase motors are self-starting and more compact than the equivalent single-phase motor.
Read the label. A gas heater will have three plumbing pipes connected.One is a gas supply. An electric heater will only have two plumbing pipes but it will have an electical conduit or electrical wire feed line.
A.C. is generated, transmitted, and distributed as three phase.
