A new chapter 5 has been added to report KD 200 in which the measurements of the VIRYA-4.2 generator are given. In chapter 5 the estimated characteristics are given for 26 V star. The characteristics for 26 V star are derived from the measured characteristics for 30 V star. Use of this generator for 26 V star might be useful for situations where power is needed already at a very low rotational speed.
