If you have a 200 amp main breaker, it will trip when any one of three phases exceeds 200 amps. This does not give you 600 amps total, only 200 amps total, but on each of three phases. Your three phase machinery and equipment will likely load all phases evenly, and a good electrical design will load your lights and receptacles evenly on all three phases. Doing this reduces the possibility that two phases are loaded at 100 amps, but one is loaded at 205 amps, so the main trips for example.
Assuming single phase voltage 220 Volts AC, the maximum current would be approximately 25 amps.
We often see the peak and trough (maximum positive and maximum negative excursions) of the sine wave considered as points of momentarily constant voltage. Those points are at phase angles of 90 degrees and at 270 degrees.
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
US homes use a 240 volt single phase 'Edison' system. It is a 3-wire (4 with the ground) system. Phase to phase measures 240v, while each phase to neutral measures 120v.
in a circuit of pure Resistance (r), IE. voltage source (12 v DC battery) and pure resistance (a light bulb). the voltage (v) and current (i) will be in phase. by adding capacitors and/or inductors to the circuit V and I will be pulled out of phase.
Not where(?)
Adding a capacitor in parallel with our load(inductive) this would make our voltage and currents in phase n hence a maximum power factor.
The testing phase consumes the maximum effort in waterfall model.
The primary advantage is that, for a given load, a three-phase system requires less copper for tranmission/distribution than an equivalent single-phase system would require. Other advantages include the fact that three-phase machines are smaller than single-phase machines of similar rating.
Homes in Canada use 240/120 volts at 60 cycles per second (60Hz) single phase. It is a split-phase system that delivers 240 volts to large domestic appliances (e.g. washing machines, dryers, air-conditioners, etc.) and 120 volts to lights and general socket outlets used for small appliances (coffee machines, electric shavers, televisions, etc.).
In a normal cell, DNA content is at a maximum in G2 phase.
before two alternators can be connected in parallel, the output voltage of the two machines should be the same, the phase rotation of the machines must be the same, and the output voltages of the two machines must be in phase.
Single phasing preventor is an electronic circuit which prevents the Thee phase operated Electrical machines from single phase cut off, Phase reversal and phase imbalance.

Preparedness
Three phase power is always delivering power on one of the phase continuously. This is very useful to manufacturing industries to operate the machines, which require high power utilization.
