What is the difference between single phase and three phase voltage measurement?
Phasing, or the number of phases in an electrical system has nothing to do with the voltage. A single phase and three phase supply could have a voltage supply of any given voltage from virtually 0 to infinity. Most single phase power supplies in the US are 120/208-240 volt. Three phase power supplies are typically 120/208 to 277/480 volt.
What are advantages in THREE phase UPS over SINGLE phase UPS?
You need to match the UPS to the service. If it is three phase you need a three phase UPS, and vice versa for single phase. It isn't a case of being better, it is a situation where you need to match your application.
Which rectifier type welding machine is better single phase or three phase as far as safety is concerned?
One is just as safe as the other. The deciding factor here is what supply voltage do you have at your establishment to operate the welder a single phase or three phase service.
What are the three types of phase on its final phase?
single phase, double phase & three phase
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
Can you use single phase kwh meter for three phase load?
No. For three phase, you need a minimum of a two element meter.

How do you connect two single phase watt-hour meters to measure three phase lines?
Two single phase meters are not needed. A three phase meter is manufactured and is used when installing a three phase electrical distribution.
How would a three phase meter reading compare to three single phase meters connected to the same service?
The reading on the 3-ph meter would equal the sum of the three separate readings on the single-phase meters. The neutral sides of the single phase meters do not need to be connected to the neutral wire as long as they are connected together.
How does a 3 phase meter handle using on 220 volt single phase and does the meter measure the wattage usage accurately?
A 3-phase meter measures the sum of the power in the three phases, so if power is drawn on one phase only it will still be correctly measured.
What are advantages in THREE phase UPS over SINGLE phase UPS?
You need to match the UPS to the service. If it is three phase you need a three phase UPS, and vice versa for single phase. It isn't a case of being better, it is a situation where you need to match your application.
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole

What are the three types of phase on its final phase?
single phase, double phase & three phase
What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
