Dual Channel AVR The Automatic Voltage Regulator (AVR) Control Panel is designed for use with Low Voltage A.C. Generator. The AVR panel is comprises of voltage control circuits, meterings and protection. The AVR will supply power to the exciter field of A. C. Generator and will maintain generator voltage wihin close limits for any load, from no load to full load. The AVR panel has provision for Two Auto modes. Auto mode has got two AVRs (AVR-1 and AVR-2) AVR selector switch is provided to select AVR-1 or AVR-2 The AVR panel is capable of providing large field forcing voltage to the exciter field to achieve fast voltage recovery under transient conditions. Clsoe voltage regulation of the A. C. Generator is ensured by a high gain amplifier and a Thyristor Convertor. Unbalance load on 3 phase A. C. Generator also produces regulation figures out side limit. The main function of the AVR panel is to regulate the terminal voltage of the generator, safe operation for under speed running, to facilitate parallel operation among generators, to vary terminal voltage by means of V-Trim pot and to read / record various excitation parameters. The input to this system is provided from the generators terminals and the out put of the system is connected to exciter field of the generator. Note: Specifications and the image may vary As per customer requirement. |
