When to Use an Automatic Voltage Controller?
Automatic Voltage Controllers
An Automatic voltage controller (AVC) is an electronic gadget that supplies a steady voltage level to electrical gear on a similar load. The AVC directs voltage varieties to convey consistent, solid force supply. Without an automatic voltage controller, voltage can hang, spike or flood and harm electrical gadgets.
When to Use an Automatic Voltage Controller?
The Automatic voltage controllers work where voltage guideline can't be accomplished by changing the size of the conductor or the source. In electrical gear like alternators, the heap can move out of nowhere. For this situation, the excitation framework should likewise change to give steady voltage under the new burden condition. The automatic voltage controller works in the exciter field and changes the exciter yield voltage, and the field current.
Types of Automatic Voltage Controller:
1.     Balanced Type Automatic Voltage Controller: It helps Voltage is low during daytime and high during night hours. Moreover, on holidays, peak hours, rainy days and when the agricultural and industrial load is switched off, the voltage rises sharply which is more dangerous.
2.     Automatic Voltage Controller with Bypass arrangement:  AVC introduced with a TRF can be circumvented and load associated with mains to work with the maintenance or periodical upkeep of the AVR. By sidestep board we can sidestep the AVR inside no time without influencing the progression of electrical force.
3.     Unbalanced Type Automatic Voltage Controller:  No state power board can guarantee consistent voltage to the machine in light of long and insufficient circulation lines and load burden on dissemination transformers. By and large, Voltage is low during daytime and high during night hours. Also, on vacations, top hours, blustery days and when the farming and modern burden is turned off, the voltage rises forcefully which is more hazardous.
4.     Automatic Voltage Controller with Isolation: In typical condition transformer is working in ordinary tap, during high temperature and high stacking on transformer will cause a voltage drop in load side and a similar proportion of voltage drop addressing in confinement transformer. AVR continually checks the base voltage and information voltage that is giving from detachment transformer. In this condition AVR assume it's part as per the setting esteems.
