What Is The Departure Of Unmarried Stage Too 3 Stage Generators?

What is the divergence of Single Phase in addition to Three Phase Generators?
Three Phase Generator Produce 3 times the ability charge compared to the Single Phase Generator.
Differences of Single Phase in addition to Three Phase generators.

GENERATOR
Generator or Alternator is a device that tin convert displace unloosen energy into electrical ability alongside the regulation of magnetic induction.

Two types of generators:
  1. Direct electrical flow or DC Generators
  2. Alternating Current or air conditioning Generators
Alternating Current Generator
Alternating Current Generators, commonly referred to equally Alternators, are divided into ii types according to their output voltage (Output Voltage), namely:
  • Single Phase Generators
  • Three Phase Generators

What is the divergence of Single Phase in addition to Three Phase Generators?

Single Phase Generators

Single Phase Generator has ii output cables, namely:
  • Phase Cable
  • Neutral Cable
Single Phase Generator has exclusively 1 Output Phase or several coils that connected inwards serial circuit.

The output voltage produced past times a Single Phase generators is commonly 220 volts (this voltage is measured betwixt Phase in addition to Neutral output cables).

220 Volt voltage inwards a Single Phase generators does non hateful that Neutral has a value of 0 Volts, in addition to Phase has a value of 220 Volts.

Neutral cable inwards a Single Phase generators
The neutral cable inwards Single Phase generator has a potential value (not zero), but the divergence or potential divergence betwixt the stage betoken in addition to the neutral divergence inwards value is 220 Volt.
Voltage is The Difference of Potential
Therefore, commonly ii output cables from Single Phase generator if nosotros attempt alongside Testpen are both lit, but alongside dissimilar voltage values.


Three Phase Generators
Difference of Single Phase in addition to Three Phase Generators
Three Phase Generators has 4 output cables, namely:
  • 1st Phase Cable  (Phase R)
  • 2nd Phase Cable (Phase S)
  • 3rd Phase Cable (Phase T)
  • Neutral Cable
Three Phase Generators has 3 Phase coils which hit Output voltage 380V or 415V, measured betwixt stage to stage alongside dissimilar phases, in addition to output voltage 220 Volts measured betwixt 1 stage alongside Neutral cable.

Three stage at this Alternator is commonly given the symbol Phase R, S, T (L1, L2, L3) in addition to due north for Neutral output cable.

Neutral cable inwards Three stage generators
Neutral generated from this Three Phase Alternator, is obtained from the results of the 3 stage coils connected star (Star).

The divergence inwards voltage values betwixt the 3 phases at the Alternator is caused past times sine waves that overlap or chase each other, in addition to it tin hold out said that the 3 Phase of this Generator convey dissimilar Phase angles of 120 degrees.

So that the divergence of potential that occurs is obtained past times 380V, alongside the divergence inwards stage potential alongside neutral is 220 Volts. The Neutral Point on the 3 stage alternator has a value of 0 volts.


Difference of Single Phase in addition to Three Phase Generators

The next are around of the differences betwixt Single Phase in addition to Three Generators.

1. Potential divergence (voltage) betwixt Phase Cable in addition to Neutral Cable inwards Single Phase Generator in addition to Three Phase Generator both convey a 220 Volt difference.

If Three stage generator, the Neutral cable voltage is 0 Volts obtained from the star connectedness (Star) of the 3 Phase coil, piece inwards the Single Phase Generator the Value of Neutral Voltage is non 0 volts, The value of the Neutral voltage changes according to the alter inwards the Voltage value of the Phase cable, but nonetheless has a divergence of 220 Volts betwixt the ii cables, So that inwards Single Phase tin hold out Phase in addition to Neutral cable has voltage.

2. Single stage Generators has a proficient Power Factor value, Power Factor value inwards Single generators is 1, So that the existent ability magnitude on the generator is equal to the active ability that tin hold out released.

Whereas inwards the Three Phase Generator has Power Factor Value below 1 (one). So that at that spot are 3 types of ability inwards the 3 stage generator, namely:
  • Real Power (KVA)
  • Active Power (KW)
  • Reactive Power (Kvar)
Usually Power Factor inwards Three stage generators has a value of 0.80. So that the ability that tin hold out used is exclusively 80% of the Power Generator.

3. Single Phase generators exclusively has 1 output stage cable, thus that maximum ability usage tin exclusively hold out used for the ability capacity of the generator.

As an example:
If Single stage Generator has grand Watts of ability (1 KW), it is used to provide residential electricity, If 1 trouble solid needs 220 Volt electricity alongside 500 Watts of power, then:
  • Real Power Generator: grand Watts (1 KW)
  • Cosphi: 1
  • Active Power: grand Watt x 1 = grand Watt
  • Load 1 trouble solid = 500 Watts
  • Then: grand watts: 500 Watts = 2 (two) houses.
  • This generator is exclusively able to provide electricity for 2 (two) houses.

Whereas inwards the Three Phase Generator, it has 3 output Phase cables, thus that ability consumption tin hold out used equally much equally 3 times the ability of the Generator.

As an example:
If an air conditioning 3 Phase Generator is written to convey 1250 VA (1.25 KVA), it is used to provide residential electricity, If 1 trouble solid needs 220 Volt electricity alongside 500 Watts of power, then:
  • Real Power: 1250 VA (1.25 KVA)
  • Cosphi: 0.8
  • Active Power: 1250 VA x 0.8 = grand Watt
  • Load 1 trouble solid = 500 Watts
  • So, grand watts: 500 Watts = 2 (two) houses.
Each Phase Generator is capable of supplying 2 (two) housing units, the full trouble solid that tin hold out supplied past times this air conditioning 3 Phase Generator is:

(3 Phase x grand Watt) / 500 watts (one house) = 6 (six) houses.
