Lost in Translation - Power Requirements

AI Thread Summary
The discussion addresses the electrical requirements for a water system being imported from Hong Kong, which operates on single phase 240V at 50Hz. The user seeks clarification on whether a standard U.S. power supply of 230V at 60Hz will be compatible and if a portable generator can support this setup. It is noted that while U.S. generators typically output 120V, some can provide 240V, but the frequency difference may cause issues with motors in the system, potentially leading to overheating. Custom wiring may be necessary to accommodate the 230V requirement. Understanding these power specifications is crucial for the successful operation of the imported equipment.

Hello!

This is my first post but I have been a lurker for a long time!

I am starting my own business in the U.S. and have run into a bit of lost in translation when it comes to the electrical requirements needed. I am importing a water system from Hong Kong that is based on:

Single phase / 240V - 50Hz

They know I am from the U.S, and they asked me to confirm that the following power supply is correct:

Main incoming Single Phase / 230V - 60Hz

Is this a standard power supply that will work with a portable generator? Will I need to have a custom generator built? Let me know if there are any questions and I will try my best to answer them.

Thanks in advance for the help!

The US power should be close enough to work OK.
 
A portable generator in the US would normally generate 120 volts, not 230 volts.
Some do provide 240 volt outputs though.

For example see this one:
http://www.frys.com/product/5234037...vA28cOhXA__.node3?site=sr:SEARCH:MAIN_RSLT_PG
27.5 amps at 120 volts.

US houses have 230 volts center tapped supplied. Outlets give the center tap and one side of the input. So, you get 115 volts or so.

There is 230 volts available and you can get special wiring done to provide 230 volts for the water heater.
 
The 50 hertz may be a problem is you have a motor in the water system.
The motor will operate faster on 60 hertz and ? may overheat.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
