In this digital age, a stable power supply is an essential need to running a business without any hindrances. Voltage spikes, blackouts, faults in distribution system, etc. are some of the causes of power disturbances. With most new systems becoming intolerant to power disruptions, any such disturbance can lead to huge losses. The AC Automatic Voltage Regulator (AVR) is a device designed to regulate voltage automatically– that is, to take a fluctuating voltage level and turn it into a constant voltage level. There are many types of automatic voltage regulators.

One of the types used for household applications is a Constant-Voltage transformer which is further broadly categorized into two most common types, which are:

I. Relay type (within 4 percent tolerance of acceptable input voltage range)

II. Servo type (accurate to 0.5 percent tolerance of acceptable input voltage range)

The structure of such a transformer can be of two types (most commonly):


  • Butler winding E-type Ferrite core
  • Toroidal Grain Oriented Silicon Steel

Efficiency at full load is typically in the range of 89% to 93%. However, at low loads, efficiency can drop below 60%. Therefore the winding material of a transformer is crucial, the three materials used for winding (readily available) are:

  • Copper
  • Copper coated black Iron wire
  • Aluminum

Power quality problems are widely prevalent with the increasing level for automation in industry as well as commercial buildings. The basic power quality problems are harmonic distortion, transients and noise, ground faults and voltage fluctuations. Harmonics is an important power quality factor.
