Squirrel Cage Induction Motor Animation
Stator view Three-phase sinusoidal balanced excitation in 3 stator phases produces a sinusoidally distributed field rotating at the excitation frequency ωs. This field can be viewed as being created by…
Difference Between Squirrel Cage and Slip Ring Motors
A wound-rotor motor (Slip Ring Motor) is a type of induction motor where the rotor windings are connected through slip rings to external resistances. Adjusting the resistance allows control of…
What is a Transformer Tap Changer
A tap changer is a device fitted to power transformers for regulation of the output voltage to required levels. This is normally achieved by changing the ratios of the transformers…
Types of Generators
Essentially, there are two basic types of generators: • DC generators • AC generators: Asynchronous (Induction) generators and Synchronous generators INDUCTION GENERATORS The induction generator is nothing more than an…
Instrumentation Cable trays Installation in vertical orientation
The article describes a improvement for better life and easy maintenance for instrumentation cable trays for industry. The practices if applied can be a better choice over a traditional approach…
Redundant Power Supply for Critical Field Panels
The Critical applications where availability of continuous power supply is required can be met with hot swappable/redundant 24 vdc power supply. This is useful for increasing the availability of system…
Worldwide Voltage & Frequency Values
The voltage and frequency of alternating current (AC) electricity used in homes varies from country to country throughout the world. Typically either 110-volt AC (110V) or 220-volt AC (220V) are…
