AC Generator Voltage Regulators
Because the voltage from an AC generator varies as the output load and power factor change, a voltage regulator circuit is necessary to permit continuity of the desired output voltage.…
Three Phase AC Generators
The principles of a three-phase generator are basically the same as that of a single-phase generator, except that there are three equally-spaced windings and three output voltages that are all…
Types of AC Generators
As previously discussed, there are two types of AC generators: the stationary field, rotating armature; and the rotating field, stationary armature. Small AC generators usually have a stationary field and…
Parallel AC Generators
Paralleling AC Generators Most electrical power grids and distribution systems have more than one AC generator operating at one time. Normally, two or more generators are operated in parallel in…
AC Generator Nameplate Ratings
Typical name plate data for an AC generator (Figure) includes: (1) manufacturer; (2) serial number and type number; (3) speed (rpm), number of poles, frequency of output, number of phases,…
PLC Program to Read Temperature in PLC
This is a PLC Program to read the temperature in PLC. Learn PLC programming using example problems and solutions.
Losses in AC Generator
The load current flows through the armature in all AC generators. Like any coil, the armature has some amount of resistance and inductive reactance. The combination of these make up…
AC Generator Theory
AC generators are widely used to produce AC voltage. To understand how these generators operate, the basic theory of operation must first be understood. Theory of Operation A simple AC…
PLC Program for Control Valve Scaling
PLC Analog Scaling example for the valve. We discuss about PLC Program for Control Valve Scaling using Siemens PLC Programming software.
AC Generator Parts
AC generators are widely used to produce AC voltage. To understand how these generators operate, the function of each component of the generator must first be understood. Field The field…
