WWW.SHRPISHRO.COM AVR's are normally used in the Diesel Generators.They are used to control the output voltage depending upon load connected , such that, the load will not cause any voltage fluctuation and damage to the DG. Automatic Voltage Regulator.It is important part in Synchronous Generators, it controls the output voltage of the generator by controlling its excitation current. Thus it can control the output Reactive Power of the Generator. AVR increase or decrease excitation voltage for linear voltage.Frequency depends on primover speed. It is a device used to maintain a constant voltage at the alternators terminals. It functions by maintaining the excitation required to maintain the terminal voltage of the alternator with change in the load. بردهای دیپ سی. کومپ. داتکم. امکو .جی ای سی . همتک .ولتاژ رگلاتور .محرک سوخت deep sea electronics plc+ comap electronics plc +hamtakelectronics plc+ datakom electronics plc emko electronics plc +gac governors+avr automatic voltage regulator +actuator .external.intergal+pick up+kuze mwm plc 403c,40315g,404c,1103g-1104 ,1106c,1004tag,1006tag,2006t,2506 ,3012tag,3008tag.4006tag,4008t,40012tag,4016tag- kolbenschmit, donladson, cat,fram, perkins, volvo,cummins mann , fleetguard , hengst , wix , baldwin
