Why three phase meter is better than single phase meter?
A three-phase meter can be used for single phase while the reverse is not the case.
What is the use of CT METER?
is 3 phase Meter electicity to for the measurement of elektricity 3 phase.
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.
Reverse running of three phase meter?
The reverse running of a three phase meter is possible when one of the meter's two potential coils fails. This is a problem found typically on a Delta service. A three phase meter in this condition is damaged and will report lower energy use than actual.
What will happen if we use current transformer of different rating for each phase in three phase supply?
A current transformer has to have the same ratio as the meter that it drives. Full scale deflection on the meter is 5 amps which equals the maximum allowed current on the phase that it is reading. A different ratio on the CT to meter would show an erroneous reading on the meter depending on the ratio of the connected CT. To keep costs down the meter is common to all three phases and is read by connecting the meter to the phase CT through a three position switch.
How many feeder you can use for chiller?
One feeder will do the job. The definition of a feeder in the electrical trade is a set of conductors that supply a source to a load. The sizing of the feeders will depend on what the load current is. The wire count of the feeder will be dependant upon whether the load is single phase or three phase.

Can you use single phase kwh meter for three phase load?
No, a single phase kWh meter is designed to measure the energy consumption of single phase loads only. To measure the energy consumption of a three phase load, you would need a three phase kWh meter specifically designed for that purpose. Using a single phase meter for a three phase load would not provide accurate energy consumption readings.

What is the Phase to phase clearance for 33KV sub station?
1.2 meter
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.
Two phase supply to transformer in panels taking out single phase supply?
Your question is rather confusing, as you do not specify what you mean by 'panels'. Your reference to a 'two-phase' supply is also confusing because two-phase supplies are an archaic precursor to 'three-phase' supplies, and it's unlikely you'll come across any two-phase supplies anywhere these days!
How is a IDMT relay used to give protection against a phase to earth fault a phase to phase fault on a feeder?
As with any IDMT relay the higher the fault current the quicker the trip time.
Reverse running of three phase meter?
The reverse running of a three phase meter is possible when one of the meter's two potential coils fails. This is a problem found typically on a Delta service. A three phase meter in this condition is damaged and will report lower energy use than actual.
Can two or more 3 phase motors be fed from same feeder?
yes they must be protected individually
What is the head stud tension for a 1985 g200 Isuzu?
Head stud tension on Isuzu G200 Phase 1. 29ft/lbs or 39 newton meter Phase 2. 54ft/lbs or 73 newton meter Phase 3. 72ft/lbs or 98 newton meter
