1.	If suppose OCC is conducted at speed n1, where n1< nrated, OCC will lie ____________(a) Above OCC at nrated(b) On OCC at nrated(c) Below OCC at nrated(d) Can’t comment by only speed informationThis question was posed to me in an interview.This key question is from No Load with On Load Characteristics of DC Generator in portion DC Generator of DC Machines
Answer» RIGHT choice is (c) Below OCC at nrated The BEST I can explain: For a less speed than the rated one, residual voltage appearing at TERMINAL call VOC will also be less than Voc at rated value, it will vary in parallel manner but will never INTERSECT OCC at rated speed.
