Static Excitation Panels as per client requirements GENERAL DESCRIPTION
- The Voltage Control Unit(AVR) is a solid state, encapsulated, state of the art design with latest technology.
- The AVR is supplying power to the exciter field of A.C. generator and will maintain generator voltage within close limits from no load to full load, with a frequency change of not more than +- 4%.
- Upon application or rejection of rated load, the generator voltage recovers to nominal value within 0.5 sec. However, the transient performance is mainly dependent upon the exciter & a.c. generator design aspects.
- Under some circumstances the a.c. generator wave shape changes considerably from no-load to rated load due to the typw of load, hence the r.m.s average or the peak voltage does not stay in proportion. For more than 10% harmonic distortion, the voltage regulation may be outside the limit specified.
- Unbalanced load on 3 phase a.c. generators also produces regulation figures outside the limit.
- AVR has been tested at factory and set to standard voltage, frequency and stability prior t the despatch.
- AVR has been incorporated with special filters to perform satisfactorily or no linear loads.
