Isolation Transformer – Working Principle, Benefits & Applications

In order to understand the isolation transformer, let us first understand isolation necessity which is protection from circuits, equipment, and people from shocks and short circuits. Isolation Transformers in India are widely used in various parts of the industry but what needs to be understood here that this can be easily explained or its working can be explained with few examples from plumbing.

Basics

Have you ever noticed a situation, where hot water is coming out of cold water faucets? It is the same situation here that needs to be prevented through isolation transformers. So, the fault here is the common point, where unwanted crossover happened that needs to be curbed using isolation transformers.

Working Principle

  • Isolation or galvanic isolation, simply means no direct conduction exists for the current to flow or no physical connection for the current to flow. Devices that help in achieving isolation can be electromagnetic, capacitive, or optical devices.
  • Unwanted currents are isolated both physically and electrically from the circuitry. Separated circuits get required signals and power transferred across them.
  • To protect against electric shock between the ground and energized conductors, isolation transformers with a ratio of 1:1 between the primary and secondary windings are used.

Benefits

  • Safety from Faulty equipment.
  • Safe and accurate measurements.
  • Ground loops avoided.
  • One part of an electrical system can be physical separated from another.

Applications

  • Used in pulse circuits.
  • Used in medical equipment to get electrical isolation.
  • Used devices that are not at ground potential to provide the power supply.
  • To provide safety in electronics testing and servicing.
  • Used to reduce electrical noise.

If looking for the top-quality servo voltage stabilizer or isolation transformers, Aditya Powers & Controls is the right option to consider. They are known for their supreme quality, high efficiency, less power consumption, and durability of the products.

Difference Between Voltage Stabilizer and Transformer

The stability of voltage and smooth power flow define safety and performance in contemporary electrical systems. Transformers and voltage stabilizers are both rather critical, even if their uses are different. That's why many depend on the best voltage stabilizer company in India to get voltage stabilizer. Though, many prefer to get transformers for guarding machines from fluctuating voltage levels. But, what are the difference between these two? Let's know! What Is the Main Difference Between a Voltage Stabilizer and a Transformer? The following are the main differences between voltage stabilizers and transformers: Purpose A transformer adjusts voltage levels to meet power transmission requirements by either increasing (step-up) or decreasing (step-down). A voltage stabilizer, on the other hand, keeps the output voltage constant even when the input fluctuates. Functionality Transformers use electromagnetic induction to move electrical energy between circuits. Stabilizers auto...
