The automatic voltage regulators reduce the overvoltages which occur because of the sudden loss of load on the system. This delivers electrical current to the field terminal of the alternator, causing it to switch on and deliver a charge to the battery. In DC supply system the voltage can be controlled by using over compound generators in case of feeders of equal length, but in the case of feeders of different lengths the voltage at the end of each feeder is kept constant using feeder booster. Your article is very helpful regarding automatic voltage regulator. The error signal is then used to adjust the field current by increasing or decreasing the current flow to an exciter stator, which in turn will lead to a lower or higher voltage at the main stator terminals. https://" : " http://");document.write(unescape("%3Cspan id='cnzz_stat_icon_1261919589'%3E%3C/span%3E%3Cscript src='" + cnzz_protocol + "s4.cnzz.com/z_stat.php%3Fid%3D1261919589%26show%3Dpic' type='text/javascript'%3E%3C/script%3E")); Voltage regulator (referred to as AVR) is designed for, After the total load of the system is measured by the electric load detector, a signal is sent to the generator computer, and then the generator voltage, Working Principle and Performance Characteristics of High Voltage Generator Set, What Industry Needs a Standby Diesel Generator Set.
