Synchronization of two or three generators

Generally the generators are synchrozised by checking three conditions
1. their terminal voltages must be the same
2.their frequencies must be same
3.their phase sequence must be same
if any one of the conditions are not satisfied and they are connected in parallel then the machines will be burnt with in a fraction of second

Procedures to synchronize generators in parallel?

You adjust the voltage and RPM on the second generator to be slightly higher than the first. How much higher depends on the system and generator design.

While monitoring a synchrometer, you pick a relative phase position (again, depending on design) and close the second generator to the first at the selected moment in phase/time.

You immediately monitor and adjust power and vars to make sure the second generator is not too over or under loaded.

Uses Of Signal and Function Generators


A signal generator generates either audio or RF frequencies (depending on the capabilities and designed purpose of the generator) for testing other electronics equipment. Makes it easier to make tests on a device without having to have it "in circuit". It's a lot easier to test a piece of equipment on a work bench rather than trying to test it in place.

A function generator supplies TTL (transistor to transistor) square wave pulses, sine and sawtooth wave forms for various testing purposes. It's a lot easier to work on something on the work bench and being able to remove a

circuit board and just supply power and a signal saves having to take a whole piece of equipment into the shop. Then again, you also can use an oscilloscope for troubleshooting when you jave a good, known signal to work with. That applies to both types of generators.
